The sinking of the RMS Titanic occurred on the night of 14 April through to the morning of 15 April 1912 in the north Atlantic Ocean, four days into her maiden voyage from Southampton to New York City. The largest passenger liner in service at the time, Titanic had an estimated 2,224 people on board when she struck an iceberg at 23:40 (ship's time) on Sunday, 14 April 1912. She sank two hours and forty minutes later at 02:20 (05:18 GMT) on Monday, 15 April, resulting in the deaths of more than 1,500 people, making it one of the deadliest peacetime maritime disasters in history.

Titanic had received several warnings of sea ice during 14 April but was travelling near her maximum speed when she sighted the iceberg. Unable to turn quickly enough, the ship suffered a glancing blow that buckled her starboard (right) side and opened five of her sixteen compartments to the sea. Titanic had been designed to stay afloat with four flooded compartments but not five, and the crew soon realised that the ship was going to sink. They used rocket flares and radio (wireless) messages to attract help as the passengers were put into lifeboats. However, there were far too few lifeboats available (although the ship carried more than she was required to have under the maritime regulations of the day) and many were not filled to their capacity due to a poorly managed evacuation.

The ship broke up as she sank with over a thousand passengers and crew members still aboard. Almost all those who jumped or fell into the water died from hypothermia within minutes. RMS Carpathia arrived on the scene about an hour and a half after the sinking and had rescued the last of the survivors in the lifeboats by 09:15 on 15 April, little more than 24 hours after Titanic's crew had received their first warnings of drifting ice. The disaster caused widespread public outrage over the lack of lifeboats, lax shipping regulations, and the unequal treatment of the different passenger classes aboard the ship. Inquiries set up in the wake of the disaster recommended sweeping changes to maritime regulations. This led in 1914 to the establishment of the International Convention for the Safety of Life at Sea (SOLAS), which still governs maritime safety today.

Background

At the time of her entry into service on 2 April 1912, RMS Titanic was the largest ship in the world: she and her slightly smaller sister Olympic had almost half again as much gross register tonnage as Cunard's Lusitania and Mauretania, the previous record holders, and were about 100 feet (30 m) longer. Titanic could carry 3,547 people in speed and comfort, and was built on a hitherto unprecedented scale. Her reciprocating engines were the largest that had ever been built, standing 40 feet (12 m) high and with cylinders 9 feet (2.7 m) in diameter, and she could generate more steam than any previous ship, requiring the burning of 600 long tons (610 t) of coal per day.

Her passenger accommodation was said to be "of unrivalled extent and magnificence". First Class accommodation included the most expensive seagoing real estate ever, with promenade suites costing $4,350 ($103,485 at 2012 prices) for a one-way passage. Even Third Class was unusually comfortable by contemporary standards and was supplied with plentiful quantities of good food, providing its passengers with better conditions than many of them had experienced at home.

Titanic's maiden voyage began shortly after noon on 10 April 1912 when she left Southampton on the first leg of her journey to New York. A few hours later she reached Cherbourg in France, a journey of 80 nautical miles (92 mi/148 km), where she took on passengers. Her next port of call was Queenstown (now Cobh) in Ireland, which she reached around midday on 11 April. She left in the afternoon after taking on more passengers and stores.

By the time she departed westwards across the Atlantic she was carrying 892 crew members and 1,320 passengers. This was only about half of her full passenger capacity of 2,435, as it was the low season and shipping from the UK had been disrupted by a coal miners' strike. Her passengers were a cross-section of Edwardian society, from millionaires such as John Jacob Astor and Benjamin Guggenheim, to poor emigrants from countries as disparate as Armenia, Ireland, Italy, Sweden, Syria and Russia seeking a new life in America.

Route of Titanic's maiden voyage from Southampton to New York

The ship was commanded by 62-year-old Captain Edward John Smith, the most senior of the White Star Line's captains. He had four decades of seafaring experience and had previously served as captain of Titanic's sister ship, RMS Olympic, from which he was transferred to command Titanic. The vast majority of the crew who served under him were not trained sailors, but were either engineers, firemen, or stokers, responsible for looking after the engines; or stewards and galley staff, responsible for the passengers. The 6 watch officers and 39 able-bodied seamen constituted only around 5 per cent of the crew, and most of these had been taken on at Southampton so had not had time to familiarise themselves with the ship.

The ice conditions were attributed to a mild winter that caused large numbers of icebergs to break away from the west coast of Greenland. In addition, it is now known that in January 1912, the Moon came closer to the Earth than at any time in the previous 1,400 years, at the same time as the Earth made its closest annual approach to the Sun. This caused exceptionally high tides that may have resulted in a larger number of icebergs than usual reaching the shipping lanes a few months later. The weather improved significantly during the course of the day, from brisk winds and moderate seas in the morning to a crystal-clear calm by evening, as the ship entered an arctic high pressure system. There was no moon on the clear night.

Just before the centennial of the sinking, an amateur historian published a book of research concluding that the weather conditions also favoured the creation of a mirage effect over the calm sea known as the Fata Morgana optical phenomenon, and that this facilitated the tragedy. It allegedly would have limited the ability of the ship's lookouts to see an approaching iceberg, and the ability of observers on the nearby ship, the SS Californian, which could see the Titanic in the critical hours, to recognise the distress the Titanic was in due to the collision. The scientific world has not weighed in on this new theory.

14 April 1912

Iceberg warnings (09:00–23:39)

This iceberg is thought to be the one that Titanic hit, for it was reported to be streaked with red paint from a ship's hull along its waterline on one side.

During 14 April 1912, Titanic's radio operators received six messages from other ships warning of drifting ice, which passengers on Titanic had begun to notice during the afternoon. The ice conditions in the North Atlantic were the worst for any April in the previous 50 years (which was the reason why the lookouts were unaware that they were about to steam into a line of drifting ice several miles wide and many miles long). Not all of these messages were relayed by the radio operators.

The first warning came at 09:00 from RMS Caronia reporting "bergs, growlers and field ice". Captain Smith acknowledged receipt of the message. At 13:42, RMS Baltic relayed a report from the Greek ship Athenia that she had been "passing icebergs and large quantities of field ice". This too was acknowledged by Smith, who showed the report to J. Bruce Ismay, the chairman of the White Star Line, aboard Titanic for her maiden voyage. Smith ordered a new course to be set farther south.

At 13:45, the German ship SS Amerika, which was a short distance to the south, reported she had "passed two large icebergs". This message never reached Captain Smith or the other officers on Titanic's bridge. The reason is unclear, but it may have been forgotten because the radio operators had to fix faulty equipment.

SS Californian reported "three large bergs" at 19:30, and at 21:40, the steamer Mesaba reported: "Saw much heavy pack ice and great number large icebergs. Also field ice." This message, too, never left the Titanic's radio room. The radio operator, Jack Phillips, may have failed to grasp its significance because he was preoccupied with transmitting messages for passengers via the relay station at Cape Race, Newfoundland; the radio set had broken down the day before, resulting in a backlog of messages that the two operators were trying to clear. A final warning was received at 22:30 from operator Cyril Evans of the Californian, which had halted for the night in an ice field some miles away, but Phillips cut it off and signalled back: "Shut up! Shut up! I'm working Cape Race."

Although the crew were aware of ice in the vicinity, the ship's speed was not reduced, and she continued to steam at 22 knots (41 km/h; 25 mph), only 2 knots (3.7 km/h; 2.3 mph) short of her maximum speed of 24 knots (44 km/h; 28 mph). Titanic's high speed in waters where ice had been reported was later criticised as reckless, but it reflected standard maritime practice at the time. According to Fifth Officer Harold Lowe, the custom was "to go ahead and depend upon the lookouts in the crow's nest and the watch on the bridge to pick up the ice in time to avoid hitting it."

The North Atlantic liners prioritised time-keeping above all other considerations, sticking rigidly to a schedule that would guarantee their arrival at an advertised time. They were constantly driven at close to their full speed, treating hazard warnings as advisories rather than calls to action. It was widely believed that ice posed little risk; close calls were not uncommon, and even head-on collisions had not been disastrous. In 1907 SS Kronprinz Wilhelm, a German liner, had rammed an iceberg and suffered a crushed bow, but was still able to complete her voyage. That same year, Titanic's future captain, Edward Smith, declared in an interview that he could not "imagine any condition which would cause a ship to founder. Modern shipbuilding has gone beyond that."

"Iceberg, right ahead!" (23:39)

Meeting with the iceberg

Further information: David Blair (mariner) and the missing binoculars

As Titanic approached her fatal crash, most passengers had gone to bed and command of the bridge had passed from Second Officer Charles Lightoller to First Officer William Murdoch. Lookouts Frederick Fleet and Reginald Lee were occupying the crow's nest 29 metres (95 ft) above the deck. The air temperature had dropped to near freezing and the ocean was completely calm. Colonel Archibald Gracie, one of the survivors of the disaster, later wrote that "the sea was like glass, so smooth that the stars were clearly reflected." It is now known that such exceptionally calm water is a sign of nearby pack ice.

Although the air was clear, there was no moon, and with the sea so calm, there was nothing to give away the position of the nearby icebergs; had the sea been rougher, waves breaking against the icebergs would have made them more visible. Because of a mix-up at Southampton the lookouts had no binoculars; but considering the state of optical technology of the time, binoculars would not have helped in a darkness which was total except for starlight and the ship's own lights. Even transparent objects such as lenses do not transmit 100 percent of all incident light; and the manufactured lenses of the time lacked modern coatings which enhance the gathering of light. Moreover, in extreme dimness, stray light, such as that from all the light bulbs turned on on the ship, actually impedes the unaided human eye from discerning distant objects. The lookouts were nonetheless well aware of the ice hazard, as Lightoller had ordered them and other crew members to "keep a sharp look-out for ice, particularly small ice and growlers".

At 23:39, Fleet spotted an iceberg in Titanic's path. He rang the lookout bell three times and telephoned the bridge to inform Sixth Officer James Moody, who asked: "What do you see?" Fleet replied: "Iceberg right ahead." After thanking Fleet, Moody relayed the message to Murdoch, who ordered Quartermaster Robert Hitchens to change the ship's course. Murdoch is generally believed to have given the order "Hard a'starboard" which would result in the ship's tiller being moved all the way to starboard (the right side of the ship) in an attempt turn the ship to port (left). He also rang "Full Astern" on the ship's telegraphs.

According to Fourth Officer Joseph Boxhall, Murdoch told Captain Smith that he was attempting to "hard-a-port around [the iceberg]", suggesting that he was attempting a "port around" manoeuvre – to first swing the bow around the obstacle, then swing the stern so that both ends of the ship would avoid a collision. There was a delay before either order went into effect; the steam-powered steering mechanism took up to 30 seconds to turn the ship's tiller, and the complex task of setting the engines into reverse would also have taken some time to accomplish. Because the centre turbine could not be reversed, it and the centre propeller, positioned directly forward of the ship's rudder, were simply stopped. This greatly reduced the rudder's effectiveness, thus handicapping the turning ability of the ship. Had Murdoch simply turned the ship while maintaining her forward speed, Titanic might have missed the iceberg with feet to spare.

In the event, Titanic's heading changed just in time to avoid a head-on collision, but the change in direction caused the ship to strike the iceberg with a glancing blow. An underwater spur of ice scraped along the starboard side of the ship for about seven seconds; chunks of ice dislodged from upper parts of the berg fell onto her forward decks. A few minutes later, all of Titanic's engines were stopped, leaving the ship facing north and drifting in the Labrador Current.

Effects of the collision

The iceberg buckled the plates, popping rivets and damaging a sequence of compartments. Contrary to widespread assumption, the iceberg did not slice the hull.

The impact with the iceberg was long thought to have produced a huge tear in Titanic's hull, "not less than 300 feet (91 m) in length, 10 feet (3.0 m) above the level of the keel", as one writer later put it. However, ultrasound surveys of the wreck have found that the damage consisted of six narrow openings in an area of the hull covering only about 12 to 13 square feet (1.1 to 1.2 m²) in total. According to Paul K. Matthias, who made the measurements, the damage consisted of a "series of deformations in the starboard side that start and stop along the hull ... about 10 feet [3.0 m] above the bottom of the ship."

The gaps, the longest of which measures about 39 feet (12 m) long, appear to have followed the line of the hull plates. This suggests that the iron rivets along the plate seams snapped off or popped open to create narrow gaps through which water flooded. An engineer from Titanic's builders, Harland and Wolff, suggested this scenario at a British inquiry following the disaster but his view was discounted. Titanic's discoverer Robert Ballard has commented that the assumption that the ship had suffered a massive breach was "a byproduct of the mystique of the Titanic. No one could believe that the great ship was sunk by a little sliver." Faults in the ship's hull may have been a contributing factor. Recovered pieces of Titanic's hull plates appear to have shattered on impact with the iceberg, without bending.

The plates in the central 60% of the hull were held together with triple rows of mild steel rivets, but the plates in the bow and stern were held together with double rows of wrought iron rivets which were – according to material scientists Foecke and McCarty – near their stress limits even before the collision. These 'Best' or No.3 iron rivets had a high level of slag inclusions, making them more brittle than the more usual 'Best-Best' No.4 iron rivets, and more prone to snapping when put under stress. But Tom McCluskie, a retired archivist of Harland & Wolff, pointed out that Olympic, Titanic's sister ship, was riveted with the same iron and served without incident for 25 years, surviving several major collisions, including being rammed by a British cruiser. The Olympic even rammed and sank the U boat U103 with her bow. Thereby, the stem was twisted and hull plates on the starboard side were buckled without impairing the integrity of the hull.

Above the waterline, there was little evidence of the collision. The stewards in the First Class Dining Room noticed a shudder, which they thought might have been caused by the ship shedding a propeller blade. Many of the passengers felt a bump or shudder but did not know what it was. Those on the lowest decks, nearest the site of the collision, felt it much more directly. Engine Oiler Walter Hurst recalled being "awakened by a grinding crash along the starboard side. No one was very much alarmed but knew we had struck something". Fireman George Kemish heard a "heavy thud and grinding tearing sound" from the starboard hull.

The ship began to flood immediately, with water pouring in at an estimated rate of 7 long tons (7.1 t) a second. Second Engineer J. H. Hesketh and Leading Stoker Frederick Barrett were hit by a jet of icy water in No. 6 boiler room and escaped just before the room's watertight door closed. This was an extremely dangerous situation for the engineering staff; the boilers were still full of hot high-pressure steam and there was a substantial risk that they would explode if they came into contact with the cold seawater flooding into the boiler rooms. The stokers and firemen were ordered to draw down the fires and vent the boilers, sending great quantities of steam up the funnel venting pipes. They were waist-deep in freezing water by the time they finished their work.

Annotated diagram of RMS Titanic showing the arrangement of the bulkheads. The areas of damage are shown in green. The compartments in the engineering area at the bottom of the ship are noted in blue. The scale's smallest unit is 10 feet (3.0 m) and its total length is 400 feet (120 m).

Titanic's lower decks were divided into sixteen compartments. Each was separated from its neighbour by a bulkhead running the width of the ship; there were fifteen bulkheads in all. Every bulkhead extended at least to the underside of E Deck, nominally one deck above the waterline, or about 11 feet (3.4 m). The two nearest the bow and the six nearest the stern went one deck further up.

Each bulkhead could be sealed by watertight doors. The engine rooms and boiler rooms on the Tank Top deck had vertically closing doors that could be controlled remotely from the bridge, lowered automatically by a float if water was present, or closed manually by the crew. These took about 30 seconds to close; warning bells and alternate escape routes were provided so that the crew would not be trapped by the doors. Above the Tank Top level, on the Orlop Deck, F Deck and E Deck, the doors closed horizontally and were manually operated. They could be closed at the door itself or from the deck above.

Although the watertight bulkheads extended well above the water line, they were not sealed at the top. If too many compartments were flooded, the ship's bow would settle deeper in the water, and water would spill from one compartment to the next in sequence, rather like water spilling across the top of an ice cube tray. This was what happened to Titanic, which had suffered damage to the forepeak tank, the three forward holds and No. 6 boiler room, a total of five compartments. Titanic was only designed to float with any two compartments flooded, but it could remain afloat with certain combinations of three or even four compartments (the first four) open to the ocean. With five compartments, however, the tops of the bulkheads would be submerged and the ship would continue to flood.

Captain Smith felt the collision in his cabin and came immediately to the bridge. Informed of the situation, he summoned Thomas Andrews, Titanic's builder, who was among a party of engineers from Harland and Wolff observing the ship's first passenger voyage. The ship was listing five degrees to starboard and was two degrees down by the head within only a few minutes of the collision. Smith and Andrews went below and found that the forward cargo holds, the mailroom and the squash court were flooded, while No. 6 boiler room was already filled to a depth of 14 feet (4.3 m). Water was spilling over into No. 5 boiler room, and crewmen there were battling to pump it out.

Within only 45 minutes of the collision, at least 13,500 long tons (13,700 t) of water had entered the ship. This was far too much for Titanic's ballast and bilge pumps to handle; the total pumping capacity of all the pumps combined was only 1,700 long tons (1,700 t) per hour. Seawater was pouring into Titanic 15 times faster than it could be pumped out. Andrews informed the captain that the ship was doomed and that she could remain afloat for no longer than about two hours.

From the time of the collision to the moment of her sinking, at least 35,000 long tons (36,000 t) of water flooded into Titanic, causing her displacement to nearly double from 43,300 long tons (44,000 t) to over 83,000 long tons (84,000 t). The flooding did not proceed at a constant pace, nor was it distributed evenly throughout the ship, due to the configuration of the flooded compartments. Her initial list to starboard was caused by asymmetrical flooding of the starboard side as water poured down a passageway at the bottom of the ship. When the passageway was fully flooded, the list corrected itself but the ship later began to list to port by up to 10° as that side also flooded asymmetrically.

Titanic's down angle altered fairly rapidly from 0° to about 4.5° during the first hour after the collision, but the rate at which the ship went down slowed greatly for the second hour, worsening only to about 5°. This gave many of those aboard a false sense of hope that the ship might stay afloat long enough for them to be rescued. By 1:30, however, the sinking rate of the front section increased until Titanic reached a down angle of about 10°.

15 April 1912

Preparing to evacuate (00:05–00:45)

Edward J. Smith, captain of Titanic, in 1911

At 00:05 on 15 April, Captain Smith ordered the ship's lifeboats to be uncovered and the passengers to be mustered. He also ordered the radio operators to begin sending distress calls, which wrongly placed the ship on the west side of the ice belt and directed rescuers to a position that turned out to be inaccurate by about 13.5 nautical miles (15.5 mi / 25 km). Below decks, water was pouring into the lowest levels of the ship. As the mail room flooded, the mail sorters made an ultimately futile attempt to save the 400,000 items of mail being carried aboard Titanic. Elsewhere, air could be heard being forced out by inrushing water. Above them, stewards went from door to door, rousing sleeping passengers and crew – Titanic did not have a public address system – and told them to go to the Boat Deck.

The thoroughness of the muster was heavily dependent on the class of the passengers; the first-class stewards were in charge of only a few cabins, while those responsible for the second- and third-class passengers had to manage large numbers of people. The first-class stewards provided hands-on assistance, helping their charges to get dressed and bringing them out onto the deck. With far more people to deal with, the second- and third-class stewards mostly confined their efforts to throwing open doors and telling passengers to put on lifebelts and come up top. In third class, passengers were largely left to their own devices after being informed of the need to come on deck.

Many passengers and crew were reluctant to comply, either refusing to believe that there was a problem or preferring the warmth of the ship's interior to the bitterly cold night air. The passengers were not told that the ship was sinking, though a few noticed that she was listing. Around 00:15, the stewards began ordering the passengers to put on their lifebelts, though again, many passengers treated the order as a joke. Some set about playing an impromptu game of football (soccer) with the ice chunks that were now strewn across the foredeck.

It was difficult to hear anything over the noise of high-pressure steam being vented from the boilers. Lawrence Beesley described the sound as "a harsh, deafening boom that made conversation difficult; if one imagines 20 locomotives blowing off steam in a low key it would give some idea of the unpleasant sound that met us as we climbed out on the top deck." The noise was so great that the crew had to rely on hand signals to communicate on the deck.

Captain Smith was faced with the fact that there were too few lifeboats to save everyone onboard. Titanic had a total of 20 lifeboats, comprising 16 wooden boats on davits, 8 on either side of the ship, and 4 collapsible boats with wooden bottoms and canvas sides. The collapsibles were stored upside down with the sides folded in, and would have to be erected and moved to the davits for launching. Two were stored under the wooden boats and the other two were lashed atop the officers' quarters. The position of the latter would make them extremely difficult to launch, as they weighed several tons each and had to be manhandled down to the boat deck.

On average, the lifeboats could take up to 68 people each, and collectively they could accommodate 1,178 – barely half the number of people on board and only a third of the number the ship was licensed to carry. The shortage of lifeboats was not because of a lack of space – Titanic had been designed to accommodate up to 68 lifeboats – nor was it because of cost, as the price of an extra 32 lifeboats would only have been some $16,000, a tiny fraction of the $7.5 million that the company had spent on Titanic. The White Star Line had, rather, wished to have a wide promenade deck with uninterrupted views of the sea, which would have been obstructed by a continuous row of lifeboats.

The company never envisaged that all of the crew and passengers would have to be evacuated at once, as Titanic was considered almost unsinkable. The lifeboats were instead intended to be used in the event of an emergency to transfer passengers off the ship and onto a nearby vessel providing assistance. It was commonplace for liners to have far fewer lifeboats than needed to accommodate all their passengers and crew, and Titanic had more lifeboats than the outdated British regulations required. Out of 39 British liners of the time of over 10,000 long tons (10,000 t), 33 had too few lifeboat places to accommodate everyone on board.

Smith was an experienced sailor who had served for 40 years at sea, with 27 years in command. He would certainly have known that even if the boats were fully occupied, a thousand people would remain on the ship as she went down. As the enormity of what was about to happen sank in, he appears to have become paralysed by indecision. He did not issue a general call for evacuation, failed to order his officers to load the lifeboats, did not adequately organise the crew, withheld crucial information from his officers and crewmen, and gave sometimes ambiguous and impractical orders. Even some of his bridge officers were unaware for some time after the collision that the ship was sinking; Fourth Officer Joseph Boxhall did not find out until 01:15, barely an hour before the ship went down, while Quartermaster George Rowe was so unaware of the emergency that after the evacuation had started, he phoned the bridge from his watch station to ask why he had just seen a lifeboat go past. Smith did not advise his officers that the ship did not have enough lifeboats to save everyone. He did not supervise the loading of the lifeboats and seemingly made no effort to find out if his orders were being followed.

The crew was likewise unprepared for the emergency, as lifeboat training had been minimal. Only one lifeboat drill had been carried out while the ship was docked. It was a cursory effort, consisting of two boats being lowered, each manned by one officer and four men who merely rowed around the dock for a few minutes before returning to the ship. The boats were supposed to be stocked with emergency supplies but Titanic's passengers later found that they had only been partially provisioned. No lifeboat or fire drills had been carried out since Titanic left Southampton. A lifeboat drill had been scheduled for the morning before the ship sank, but was cancelled for unknown reasons by Captain Smith.

Lists had been posted on the ship allocating crew members to particular lifeboat stations, but few appeared to have read them or to have known what they were supposed to do. Most of the crew were, in any case, not seamen, and even some of those had no prior experience of rowing a boat. They were now faced with the complex task of coordinating the lowering of 20 boats carrying a possible total of 1,100 people 70 feet (21 m) down the sides of the ship. Thomas E. Bonsall, a historian of the disaster, has commented that the evacuation was so badly organised that "even if they had the number [of] lifeboats they needed, it is impossible to see how they could have launched them" given the lack of time and poor leadership.

By about 00:20, 40 minutes after the collision, the loading of the lifeboats was under way, though it was perhaps symptomatic of Captain Smith's apparent indecisiveness that it was at the suggestion of Second Officer Lightoller. As the latter recalled afterwards, "I yelled at the top of my voice, 'Hadn't we better get the women and children into the boats, sir?' He heard me and nodded reply." Smith ordered Lightoller to put the "women and children in and lower away". Lightoller took charge of the boats on the port side and Murdoch took those on the starboard side. The two officers interpreted the evacuation order differently; Murdoch took it to mean women and children first while Lightoller thought it meant women and children only. Lightoller lowered lifeboats with empty seats if there were no women and children waiting to board, while Murdoch allowed a limited number of men to board if all the nearby women and children had embarked. Neither officer knew how many people could safely be carried in the boats as they were lowered and erred on the side of caution by not filling them. They could have been lowered quite safely with their full complement of 68 people. Had this been done, an extra 500 people could have been saved; instead, hundreds of people, predominantly men, were left on board as lifeboats were launched with many seats empty.

Few passengers at first were willing to board the lifeboats and the officers in charge of the evacuation found it hard to persuade them. The millionaire John Jacob Astor declared: "We are safer here than in that little boat." Some passengers refused flatly to embark. J. Bruce Ismay, realising the need for urgency, roamed the starboard deck and urged passengers and crew to evacuate. A trickle of women, couples and single men were persuaded to board starboard lifeboat No. 7, which became the first lifeboat to be lowered.

Departure of the lifeboats (00:45–02:05)

"The Sad Parting", illustration of 1912

At 00:45 lifeboat No. 7 was rowed away from Titanic with 28 passengers on board (despite a capacity of 65). Lifeboat No. 6, on the port side, was the next to be lowered at 00:55. It also had 28 people on board, among them the "unsinkable" Margaret "Molly" Brown. Lightoller realised there was only one seaman on board and called for volunteers. Major Arthur Godfrey Peuchen of the Royal Canadian Yacht Club stepped forward and climbed down a rope into the lifeboat; he was the only male passenger whom Lightoller allowed to board during the port side evacuation. Peuchen's role highlighted a key problem during the evacuation: there were hardly any seamen to man the boats. Some had been sent below to open gangway doors to allow more passengers to be evacuated, but they never returned. They were presumably trapped and drowned by the rising water below decks.

Other crewmen fought for their lives as water continued to pour into the ship. The engineers and firemen worked to vent steam from the boilers to prevent them from exploding on contact with the cold water. They set up extra pumps in the forward compartments in a futile bid to stem the torrent, and kept the electrical generators running to maintain lights and power throughout the ship. Steward F. Dent Ray narrowly avoided being swept away when a wooden wall between his quarters and the third-class accommodation on E deck collapsed, leaving him waist-deep in water. Two engineers died in boiler room No. 5 when, at around 00:45, the bunker door separating it from the flooded No. 6 boiler room collapsed and they were swept away by "a wave of green foam".

In boiler room No. 4, at around 01:20, water began flooding in from below, possibly indicating that the bottom of the ship had also been holed by the iceberg. The flow of water soon overwhelmed the pumps and forced the firemen to evacuate the forward boiler rooms. Further aft, Chief Engineer William Bell, his engineering colleagues, and a handful of volunteer firemen and greasers stayed behind in the unflooded No. 1, 2 and 3 boiler and engine rooms. They continued working on the electrical generators in order to keep the ship's lights on and to power the radio so that distress signals could be sent. They apparently remained at their posts until the very end, ensuring that Titanic remained lit until the final minutes of the sinking. None of the ship's engineers survived. Titanic's five postal clerks were last seen struggling to save the mail bags they had rescued from the flooded mail room. They were caught by the rising water somewhere on D deck.

Many of the third-class passengers were also confronted with the sight of water pouring into their quarters on E, F and G decks. Carl Jansson, one of the relatively small number of third-class survivors, later recalled:

Then I run down to my cabin to bring my other clothes, watch and bag but only had time to take the watch and coat when water with enormous force came into the cabin and I had to rush up to the deck again where I found my friends standing with lifebelts on and with terror painted on their faces. What should I do now, with no lifebelt and no shoes and no cap?

The lifeboats were lowered every few minutes on each side, but most of the boats were greatly under-filled. No. 5 left with 41 aboard, No. 3 had 32 aboard, No. 8 left with 39 and No. 1 left with just 12 out of a capacity of 40. The evacuation did not go smoothly and passengers suffered accidents and injuries as it progressed. One woman fell between lifeboat No. 10 and the side of the ship but someone caught her by the ankle and hauled her back onto the promenade deck, where she made a second successful attempt at boarding. First-class passenger Annie Stengel broke several ribs when an overweight German-American doctor and his brother jumped into No. 5, squashing her and knocking her unconscious. The lifeboats' descent was likewise risky. No. 6 was nearly flooded during the descent by water discharging out of the ship's side, but successfully made it away from the ship. No. 3 came close to disaster when, for a time, one of the davits jammed, threatening to pitch the passengers out of the lifeboat and into the sea.

By 01:20, the seriousness of the situation was now apparent to the passengers above decks, who began saying their goodbyes, with husbands escorting their wives and children to the lifeboats. Distress rockets were fired every few minutes to attract the attention of any ships nearby and the radio operators repeatedly sent the distress signal CQD. Radio operator Harold Bride suggested to his colleague Jack Phillips that he should use the new SOS signal, as it "may be your last chance to send it". The two radio operators contacted other ships to ask for assistance. Several responded, of which RMS Carpathia was the closest, at 58 miles (93 km) away. She was a much slower vessel than Titanic and, even driven at her maximum speed of 17 kn (20 mph; 31 km/h), would have taken four hours to reach the sinking ship.

Much nearer was the SS Californian, which had warned Titanic of ice a few hours earlier. Apprehensive at his ship being caught in a large field of drift ice, the Californian's captain, Stanley Lord, had decided at about 22:00 to halt for the night and wait for daylight to find a way through the ice field. At 23:30, only 10 minutes before Titanic hit the iceberg, Californian's sole radio operator, Cyril Evans, shut his set down for the night and went to bed. On the bridge her Third Officer, Charles Groves, saw a large vessel to starboard around 10 mi (16 km) to 12 mi (19 km) away. It made a sudden turn to port and stopped. If the radio operator of the Californian had stayed at his post a mere fifteen minutes longer, hundreds of lives would have been saved. A little over an hour later, Second Officer Herbert Stone saw five white rockets exploding above the stopped ship. Unsure what the rockets meant, he called Captain Lord, who was resting in the chartroom, and reported the sighting. Lord did not act on the report, but Stone was perturbed: "A ship is not going to fire rockets at sea for nothing," he told a colleague.

Distress signal sent at about 01:40 by Titanic's radio operator, Jack Phillips, to the Russian ship SS Birma. This was one of Titanic's last intelligible radio messages.

By this time it was clear to those on Titanic that the ship was indeed sinking and there would not be enough lifeboat places for everyone. Some still clung to the hope that the worst would not happen: Lucien Smith told his wife, "It is only a matter of form to have women and children first. The ship is thoroughly equipped and everyone on her will be saved." Charlotte Colyer's husband Harvey called to his wife as she was put in a lifeboat, "Go, Lottie! For God's sake, be brave and go! I'll get a seat in another boat!"

Other couples refused to be separated. Ida Straus, the wife of Macy's department store co-owner Isidor Straus, told her husband: "We have been living together for many years. Where you go, I go." They sat down in a pair of deck chairs and waited for the end. The industrialist Benjamin Guggenheim changed out of his life vest and sweater into top hat and evening dress, and declared his wish to go down with the ship like a gentleman.

At this point, the vast majority of those who had boarded lifeboats were first- and second-class passengers. Few third-class (steerage) passengers had made it up onto the deck, and most were still lost in the maze of corridors or trapped behind barriers and partitions that segregated the accommodation for the steerage passengers from the first- and second-class areas. This segregation was not simply for social reasons, but was a requirement of United States immigration laws, which mandated that third-class passengers be segregated to control immigration and prevent the spread of infectious diseases. First- and second-class passengers on transatlantic liners disembarked at the main piers in Manhattan, but steerage passengers had to go through health checks and processing at Ellis Island. In at least some places, Titanic's crew appear to have actively hindered the steerage passengers' escape. Some of the barriers were locked and guarded by crew members, apparently to prevent the steerage passengers rushing the lifeboats. Irish survivor Margaret Murphy wrote in May 1912:

Before all the steerage passengers had even a chance of their lives, the Titanic's sailors fastened the doors and companionways leading up from the third-class section ... A crowd of men was trying to get up to a higher deck and were fighting the sailors; all striking and scuffling and swearing. Women and some children were there praying and crying. Then the sailors fastened down the hatchways leading to the third-class section. They said they wanted to keep the air down there so the vessel could stay up longer. It meant all hope was gone for those still down there.

A long and winding route had to be taken to reach topside; the steerage-class accommodation, located on decks C through G, was at the extreme ends of the decks, and so was furthest away from the lifeboats. By contrast, the first-class accommodation was located on the upper decks and so was nearest. Proximity to the lifeboats thus became a key factor in determining who got in them. To add to the difficulty, many of the steerage passengers did not understand English. It was perhaps no coincidence that English-speaking Irish immigrants were disproportionately represented among the steerage passengers who survived. Many of those who did survive owed their lives to third-class steward John Edward Hart, who organised three trips into the ship's interior to escort groups of third-class passengers up to the boat deck. Others made their way through open barriers or climbed emergency ladders.

Some, perhaps overwhelmed by it all, made no attempt to escape and stayed in their cabins or congregated in prayer in the third-class dining room. Leading Fireman Charles Hendrickson saw crowds of third-class passengers below decks with their trunks and possessions, as if waiting for someone to direct them. Psychologist Wynn Craig Wade attributes this to "stoic passivity" produced by generations of being told what to do by social superiors. August Wennerström, one of the relatively few male steerage passengers to survive, commented later that many of his companions had made no effort to save themselves. He wrote:

Hundreds were in a circle [in the third-class dining saloon] with a preacher in the middle, praying, crying, asking God and Mary to help them. They lay there and yelled, never lifting a hand to help themselves. They had lost their own will power and expected God to do all the work for them.

Launching of the last lifeboats

Lifeboat No. 15 was nearly lowered onto another lifeboat that drifted beneath it (depicted by Charles Dixon).

By 01:30, Titanic's downward angle in the water was increasing and the ship was now listing slightly more to port, but not more than 5 degrees. The deteriorating situation was reflected in the messages sent from the ship, which carried a tone of increasing desperation: "We are putting the women off in the boats" at 01:25, "Engine room getting flooded" at 01:35, and at 01:45, "Engine room full up to boilers." This was Titanic's last intelligible signal, sent as the ship's electrical system began to fail; subsequent messages were jumbled and broken. The two radio operators nonetheless continued sending out distress messages almost to the very end.

The remaining boats were filled much closer to capacity and in an increasing rush. No. 11 was filled with five people more than its rated capacity. As it was lowered, it was nearly flooded by water being pumped out of the ship, but made it safely to the sea. No. 13 narrowly avoided the same problem but those aboard were unable to release the ropes from which the boat had been lowered. It drifted astern, directly under No. 15 as it was being lowered. The ropes were cut in time and both boats made it away safely.

The first signs of panic were seen when a group of passengers attempted to rush port-side lifeboat No. 14 as it was being lowered with 40 people aboard. Fifth Officer Lowe fired three warning shots in the air to restrain the crowd, without causing injuries. No. 16 was lowered five minutes later. Among those aboard was stewardess Violet Jessop, who was to repeat the experience four years later when she survived the sinking of one of Titanic's sister ships, Britannic, in the First World War. Collapsible boat C was launched at 01:40 from a now largely deserted area of the deck, as most of those on deck had moved to the stern of the ship. It was aboard this boat that J. Bruce Ismay, Titanic's most controversial survivor, made his escape from the ship, an act later condemned as cowardice.

At 01:45, lifeboat No. 2 was lowered. While it was still at deck level, Lightoller had found the boat occupied by a number of men who, he wrote later, "weren't British, nor of the English-speaking race ... [but of] the broad category known to sailors as 'dagoes'." After he evicted them by threatening them with his revolver, he was unable to find enough women and children to fill the boat and lowered it with only 25 people on board out of a possible capacity of 40. John Jacob Astor saw his wife off to safety in No. 4 boat at 01:55 but was refused entry by Lightoller, even though 20 of the 60 seats aboard were unoccupied.

The last boat to be launched was collapsible D, which left at 02:05 with 44 people aboard. The sea had reached the boat deck and the forecastle was deep underwater. Captain Smith carried out a final tour of the deck, telling the radio operators and other crew members: "Now it's every man for himself."

As passengers and crew headed to the stern, where Father Thomas Byles was giving absolutions and hearing confessions, Titanic's band continued to play outside the gymnasium. Part of the enduring folklore of the Titanic sinking is that the band played the hymn "Nearer, My God, to Thee" as the ship sank, but this appears to be dubious. The claim surfaced among the earliest reports of the sinking, and the hymn became so closely associated with the Titanic disaster that its opening bars were carved on the grave monument of Titanic's bandmaster, Wallace Hartley, one of those who perished. Violet Jessop said in her 1934 account of the disaster that she had heard the hymn being played. In contrast, Archibald Gracie emphatically denied it in his own account, written soon after the sinking, and Radio Operator Harold Bride said that he had heard "Autumn", by which he may have meant Archibald Joyce's then-popular waltz "Songe d'Automne" (Autumn Dream). George Orrell, the bandmaster of the rescue ship, Carpathia, who spoke with survivors, related: "The ship's band in any emergency is expected to play to calm the passengers. After Titanic struck the iceberg the band began to play bright music, dance music, comic songs – anything that would prevent the passengers from becoming panic-stricken ... various awe-stricken passengers began to think of the death that faced them and asked the bandmaster to play hymns. The one which appealed to all was 'Nearer My God to Thee'." According to Gracie, who was near the band until that section of deck went under, the tunes played by the band were "cheerful" but that he didn't recognise any of them, claiming that if they had played ‘Nearer, My God, to Thee’ as claimed in the newspaper "I assuredly should have noticed it and regarded it as a tactless warning of immediate death to us all and one likely to create panic."

Bride heard the band as he left the radio cabin, which was by now awash, in the company of the other radio operator, Jack Phillips. He had just had a fight with a man who Bride thought was "a stoker, or someone from below decks", who had attempted to steal Phillips' lifebelt. Bride wrote later: "I did my duty. I hope I finished [the man]. I don't know. We left him on the cabin floor of the radio room, and he was not moving." The two radio operators went in opposite directions, Phillips aft and Bride forward towards collapsible lifeboat B.

Archibald Gracie was also heading aft, but as he made his way towards the stern he found his path blocked by "a mass of humanity several lines deep, covering the boat deck, facing us" – hundreds of steerage passengers, who had finally made it to the deck just as the last lifeboats departed. He gave up on the idea of going aft and jumped into the water to get away from the crowd. Others made no attempt to escape. The ship's designer, Thomas Andrews, was last seen in the first-class smoking room, without a lifebelt, staring at the painting above the fireplace. Captain Smith's fate is unclear, but he was reportedly seen on the bridge as the ship went down.

Last minutes of sinking (02:15–02:20)

"Nearer, My God, To Thee" – cartoon of 1912

At about 02:15, Titanic's angle in the water began to increase rapidly as water poured into previously unflooded parts of the ship through deck hatches. Her suddenly increasing angle caused what one survivor called a "giant wave" to wash along the ship from the forward end of the boat deck, sweeping many people into the sea. Chief Officer Henry Wilde, First Officer Murdoch, Second Officer Charles Lightoller and Colonel Archibald Gracie were swept away along with collapsible lifeboat B, which floated away upside-down with Harold Bride trapped underneath it. Bride, Gracie and Lightoller made it onto the boat, but Murdoch and Wilde perished in the water.

Lightoller opted to abandon his post to escape the growing crowds, and dived into the water. He was sucked into the mouth of a ventilation shaft but was blown clear by "a terrific blast of hot air" and emerged next to the capsized lifeboat. The forward funnel collapsed under its own weight, crushing several people as it fell into the water and only narrowly missing the lifeboat. It closely missed Lightoller and created a wave that washed the boat 50 yards (46 m) clear of the sinking ship. Those still on Titanic felt her structure shuddering as it underwent immense stresses. As first-class passenger Jack Thayer described it:

Occasionally there had been a muffled thud or deadened explosion within the ship. Now, without warning she seemed to start forward, moving forward and into the water at an angle of about fifteen degrees. This movement with the water rushing up toward us was accompanied by a rumbling roar, mixed with more muffled explosions. It was like standing under a steel railway bridge while an express train passes overhead mingled with the noise of a pressed steel factory and wholesale breakage of china.

Eyewitnesses saw Titanic's stern lifting high into the air as the ship tilted down in the water. It was said to have reached an angle of 30–45 degrees, "revolving apparently around a centre of gravity just astern of midships," as Lawrence Beesley later put it. Many survivors described a great noise, which some attributed to the boilers exploding. Beesley described it as "partly a groan, partly a rattle, and partly a smash, and it was not a sudden roar as an explosion would be: it went on successively for some seconds, possibly fifteen to twenty". He attributed it to "the engines and machinery coming loose from their bolts and bearings, and falling through the compartments, smashing everything in their way".

After another minute, the lights flickered once and then permanently went out, plunging Titanic into darkness. Jack Thayer recalled seeing "groups of the fifteen hundred people still aboard, clinging in clusters or bunches, like swarming bees; only to fall in masses, pairs or singly as the great afterpart of the ship, two hundred fifty feet of it, rose into the sky." The stern began to settle back before rising again to a nearly vertical 90 degree angle, where it remained for a few moments. Thayer reported that it rotated on the surface, "gradually [turning] her deck away from us, as though to hide from our sight the awful spectacle ... Then, with the deadened noise of the bursting of her last few gallant bulkheads, she slid quietly away from us into the sea."

"Sinking of the Titanic" by Henry Reuterdahl

Titanic was subjected to extreme opposing forces – water in the bow pulling her down and air in the stern forcing her to the surface – which were concentrated at one of the weakest points in the structure, the area of the engine room hatch. Shortly after the lights went out, the ship broke in two from side to side across No. 1 boiler room, just forward of the third funnel. The submerged bow may have remained attached to the stern by the keel for a short time, pulling the stern to a high angle before separating and leaving the stern to float for a few minutes longer. The forward part of the stern would have flooded very rapidly, causing it to tilt until it reached its final near-vertical position.

Titanic's surviving officers and a number of prominent survivors later testified that the ship had sunk in one piece, a belief that was mistakenly affirmed by the British and American inquiries into the disaster. Archibald Gracie stated that "Titanic's decks were intact at the time she sank, and when I sank with her, there was over seven-sixteenths of the ship already under water, and there was no indication then of any impending break of the deck or ship". However, many other survivors' accounts clearly indicated that the ship had broken in two as it was sinking. As the engines are now known to have stayed in place along with most of the boilers, the "great noise" heard by witnesses and the momentary settling of the stern were evidently caused by the break-up of the ship rather than the loosening of her fittings or boiler explosions.

After they went under, the bow and stern took only a few minutes to sink 3,795 metres (12,451 ft), spilling a trail of heavy machinery, tons of coal and great quantities of debris from Titanic's interior. The two parts of the ship landed about 600 metres (2,000 ft) apart on a gently undulating area of the seabed. The streamlined bow section continued to descend at about the angle it had taken on the surface, striking the seabed prow-first at a shallow angle at an estimated speed of 25–30 mph (40–48 km/h). Its momentum caused it to dig a deep gouge into the seabed and buried the section up to 20 metres (66 ft) deep in sediment before it came to an abrupt halt. The sudden deceleration caused the bow's structure to buckle downwards by several degrees just forward of the bridge. The decks at the rear end of the bow section, which had already been weakened during the break-up, collapsed one atop another.

The stern section seems to have descended almost vertically, probably rotating as it fell. Pockets of air still trapped in the hull imploded as it descended, tearing open the structure and ripping off the poop deck. The section landed with such force that it buried itself about 15 metres (49 ft) deep at the rudder. The decks pancaked down on top of each other and the hull plating splayed out to the sides. Debris continued to rain down across the seabed for several hours after the sinking.

Passengers and crew in the water (02:20–04:10)

Colonel Archibald Gracie, one of the survivors who made it to collapsible lifeboat B. He never recovered from his ordeal and died eight months after the sinking.

In the immediate aftermath of the sinking, hundreds of passengers and crew were left dying in the icy sea, surrounded by debris from the ship. An unknown number of people had gone down with the ship, trapped below decks or sucked down and drowned as the ship sank. Titanic's disintegration during her descent to the seabed caused buoyant chunks of debris – timber beams, wooden doors, furniture, panelling and chunks of cork from the bulkheads – to rocket to the surface. They injured and possibly killed some of the swimmers; others used the debris to try to keep themselves afloat.

The water was lethally cold, with a temperature of 28 °F (−2 °C). Second Officer Lightoller described the feeling of "a thousand knives" being driven into his body as he entered the sea. Some of those in the water would have died almost immediately from heart attacks caused by the sudden stress on their cardiovascular systems. Others progressed through the classic symptoms of hypothermia: extreme shivering at first, followed by a slowing and weakening pulse as body temperature dropped, before finally losing consciousness and dying.

Those in the lifeboats were horrified to hear the sound of what Lawrence Beesley called "every possible emotion of human fear, despair, agony, fierce resentment and blind anger mingled – I am certain of those – with notes of infinite surprise, as though each one were saying, 'How is it possible that this awful thing is happening to me? That I should be caught in this death trap?'" Jack Thayer compared it to the sound of "locusts on a summer night", while George Rheims, who jumped moments before Titanic sank, described it as "a dismal moaning sound which I won't ever forget; it came from those poor people who were floating around, calling for help. It was horrifying, mysterious, supernatural."

The noise of the people in the water screaming, yelling, and crying was a tremendous shock to the occupants of the lifeboats, many of whom had up to that moment believed that everyone had escaped before the ship sank. As Beesley later wrote, the cries "came as a thunderbolt, unexpected, inconceivable, incredible. No one in any of the boats standing off a few hundred yards away can have escaped the paralysing shock of knowing that so short a distance away a tragedy, unbelievable in its magnitude, was being enacted, which we, helpless, could in no way avert or diminish."

Only a few of those in the water survived. Among them were Archibald Gracie, Jack Thayer and Charles Lightoller, who made it to the capsized collapsible boat B. About 35 men climbed aboard the upturned hull and clung on precariously, trying to keep their balance and avoid being tipped off by the mass of swimmers around them. They paddled slowly away, ignoring the pleas of dozens of swimmers to be allowed on board. Collapsible boat A was upright but partly flooded, as its sides had not been properly raised, and its 30 or more occupants had to sit for hours in a foot of freezing water.

Farther out, the other eighteen lifeboats – most of which had empty seats – drifted as the occupants debated what, if anything, they should do to rescue the swimmers. No. 4 boat seems to have been closest to the site of the sinking at around 50 metres away; this enabled three people to swim over and be picked up before the ship sank. Five more were pulled from the water after the sinking, though two later died. In all of the other boats, the occupants eventually decided against returning, probably out of fear that they would be capsized in the attempt. Some put their objections more bluntly; Quartermaster Hitchens, commanding lifeboat No. 6, told the women aboard his boat that there was no point returning as there were "only a lot of stiffs there."

After about twenty minutes, the cries began to fade as the swimmers lapsed into unconsciousness and death. Fifth Officer Lowe, in charge of No. 14 lifeboat, "waited until the yells and shrieks had subsided for the people to thin out" before mounting the night's sole attempt to rescue those in the water. He gathered together five of the lifeboats and transferred the occupants between them to free up space in No. 14. Lowe then took a crew of seven crewmen and one male passenger who volunteered to help, and then rowed back to the site of the sinking. The whole operation took about three-quarters of an hour. By the time No. 14 headed back to the site of the sinking, almost all of those in the water were already dead and only a few voices could still be heard.

Lucy, Lady Duff-Gordon, recalled after the disaster that "the very last cry was that of a man who had been calling loudly: 'My God! My God!' He cried monotonously, in a dull, hopeless way. For an entire hour there had been an awful chorus of shrieks, gradually dying into a hopeless moan, until this last cry that I speak of. Then all was silent." Lowe and his crew found four men still alive, one of whom died shortly afterwards. Otherwise all they could see were "hundreds of bodies and lifebelts"; the dead "seemed as if they had perished with the cold as their limbs were all cramped up."

In the other boats, there was nothing the survivors could do but await the arrival of rescue ships. The air was bitterly cold and several of the boats had taken on water. The survivors could not find any food or drinkable water in the boats, and most had no lights. The situation was particularly bad aboard collapsible B, which was only kept afloat by a diminishing air pocket in the upturned hull. As dawn approached, the wind rose and the sea became increasingly choppy, forcing those on the collapsible boat to stand up to balance it. Some, exhausted by the ordeal, fell off into the sea and were drowned. It became steadily harder for the rest to keep their balance on the hull, with waves washing across it. Archibald Gracie later wrote of how he and the other survivors sitting on the upturned hull were struck by "the utter helplessness of our position."

Rescue and departure (04:10–09:15)

Collapsible lifeboat D photographed from the deck of Carpathia on the morning of 15 April 1912.

Titanic's survivors were finally rescued around 04:00 on 15 April by the RMS Carpathia, which had steamed through the night at high speed and at considerable risk, as the ship had to dodge numerous icebergs en route. Carpathia's lights were first spotted around 03:30, which greatly cheered the survivors, though it took several more hours for everyone to be brought aboard. The men on collapsible B finally managed to board two other lifeboats, but one survivor died just before the transfer was made. Collapsible A was also in trouble and was now nearly awash; more than half of those aboard had died overnight. The remainder were transferred into another lifeboat, leaving behind three bodies in the boat, which was left to drift away. It was recovered a month later by the White Star liner Oceanic, with the bodies still aboard.

Those on Carpathia were startled by the scene that greeted them as the sun came up: "fields of ice on which, like points on the landscape, rested innumerable pyramids of ice." Captain Arthur Rostron of Carpathia saw ice all around, including 20 large bergs measuring up to 200 feet (61 m) high and numerous smaller bergs, as well as ice floes and debris from Titanic. It appeared to Carpathia's passengers that their ship was in the middle of a vast white plain of ice, studded with icebergs appearing like hills in the distance.

As the lifeboats were brought alongside Carpathia, the survivors came aboard the ship by various means. Some were strong enough to climb up rope ladders; others were hoisted up in slings, and the children were hoisted in mail sacks. The last lifeboat to reach the ship was Lightoller's boat No. 12, with 74 people aboard a boat designed to carry 65. They were all on Carpathia by 09:00. There were some scenes of joy as families and friends were reunited, but in most cases hopes died as loved ones failed to reappear.

At 09:15, two more ships appeared on the scene – Mount Temple and Californian, which had finally learned of the disaster when her radio operator returned to duty – but by then there were no more survivors to be rescued. Carpathia had been bound for Fiume, Austria-Hungary, (now Rijeka, Croatia) but as she had neither the stores nor the medical facilities to cater for the survivors, Rostron ordered that a course be calculated to return the ship to New York, where the survivors could be properly looked after. Carpathia departed the area, leaving the other ships to carry out a final, fruitless, two-hour search.

Aftermath

According to an eyewitness report, there "were many pathetic scenes" when Titanic's survivors disembarked at New York.

Carpathia arrived at Pier 34 in New York on the evening of 18 April after a difficult voyage through pack ice, fog, thunderstorms and rough seas. Some 40,000 people stood on the waterfront, alerted to the disaster by a stream of radio messages from Carpathia and other ships. Due to communications difficulties, it was only after Carpathia docked – a full three days after Titanic's sinking – that the full scope of the disaster became public knowledge. The heaviest loss was in Southampton, home to most of the crew; 699 members of the crew gave Southampton addresses, and 549 Southampton residents, almost all crew, were lost in the disaster.

Even before Carpathia arrived in New York, efforts were getting underway to retrieve the dead. Four ships chartered by the White Star Line succeeded in retrieving 328 bodies; 119 were buried at sea, while the remaining 209 were brought ashore to the Canadian port of Halifax, Nova Scotia, where 150 of them were buried. Memorials were raised in various places – New York, Washington, Southampton, Liverpool, Belfast and Lichfield, among others – and ceremonies were held on both sides of the Atlantic to commemorate the dead and raise funds to aid the survivors. The bodies of most of Titanic's victims were never recovered, and the only evidence of their deaths was found 73 years later among the debris on the seabed: pairs of shoes lying side by side, where bodies had once lain before eventually decomposing in the sea waters.

The prevailing public reaction to the disaster was one of shock and outrage, directed against a number of issues and people: why were there so few lifeboats? Why had Ismay saved his own life when so many others died? Why did Titanic proceed into the icefield at full speed? The outrage was driven not least by the survivors themselves; even while they were aboard Carpathia on their way to New York, Beesley and other survivors determined to "awaken public opinion to safeguard ocean travel in the future" and wrote a public letter to The Times urging changes to maritime safety.

In places closely associated with Titanic, there was a deep sense of grief. Crowds of weeping women, the wives, sisters and mothers of crew members, gathered outside the White Star Line's offices in Southampton to find out what had happened to their loved ones – most of whom had perished. Churches in Belfast were packed and shipyard workers wept in the streets after the news was announced. The ship had been a symbol of Belfast's industrial achievements and there was not only a sense of grief but also of guilt, as those who had built Titanic came to feel that they had in some way been responsible for her loss.

"Time to get busy" by "Fisher", 1912. Public outrage at the disaster led politicians to impose new regulations on the shipping industry.

In the aftermath of the sinking, public inquiries were set up in Britain and the United States. The US inquiry began on 19 April under the chairmanship of Senator William Alden Smith, while the British inquiry commenced in London under Lord Mersey on 2 May 1912. They reached broadly similar conclusions: the regulations on the number of lifeboats that ships had to carry were out of date and inadequate; Captain Smith had failed to take proper heed of ice warnings; the lifeboats had not been properly filled or crewed; and the collision was the direct result of steaming into a danger area at too high a speed. Captain Lord of the Californian was strongly criticised by both inquiries for failing to render assistance to Titanic.

The disaster led to major changes in maritime regulations to implement new safety measures, such as ensuring that more lifeboats were provided, that lifeboat drills were properly carried out and that radio equipment on passenger ships was manned around the clock. An International Ice Patrol was set up to monitor the presence of icebergs in the North Atlantic, and maritime safety regulations were harmonised internationally through the International Convention for the Safety of Life at Sea; both measures are still in force today.

Titanic's sinking became a cultural phenomenon, commemorated by numerous artists, film-makers, writers, composers, musicians and dancers from the time immediately after the sinking to the present day. On 1 September 1985 a joint US-French expedition led by Robert Ballard found the wreck of Titanic, and the ship's rediscovery led to an explosion of interest in Titanic's story. In 1997, James Cameron's eponymous film became the first movie ever to take $1 billion at the box office, and the film's soundtrack became the best selling soundtrack recording of all time. Numerous expeditions have been launched to film the wreck and, controversially, to salvage objects from the debris field.

Although many artefacts have been recovered and conserved, the wreck itself is steadily decaying, as iron-eating bacteria consume the hull at an estimated rate of 100 kilograms (220 lb) a day. In time, Titanic's structure will collapse into a pile of iron and steel fragments. Eventually she will be reduced to a patch of rust on the seabed, with the remaining scraps of the ship's hull mingled with her more durable fittings.

Casualties and survivors

Further information: Passengers of the RMS Titanic and Crew of the RMS Titanic

The number of casualties of the sinking is unclear, due to a number of factors, including confusion over the passenger list, which included some names of people who cancelled their trip at the last minute, and the fact that several passengers travelled under aliases for various reasons and were double-counted on the casualty lists. The death toll has been put at between 1,490 and 1,635 people. The figures below are from the British Board of Trade report on the disaster.

Passengers	Category	Number aboard	Number saved	Number lost	Percentage saved	Percentage lost
Children	First Class	6	5	1	83.4%	16.6%
Children	Second Class	24	24	0	100%	0%
Children	Third Class	79	27	52	34%	66%
Women	First Class	144	140	4	97%	3%
Women	Second Class	93	80	13	86%	14%
Women	Third Class	165	76	89	46%	54%
Women	Crew	23	20	3	87%	13%
Men	First Class	175	57	118	33%	67%
Men	Second Class	168	14	154	8%	92%
Men	Third Class	462	75	387	16%	84%
Men	Crew	885	192	693	22%	78%
Total		2224	710	1514	32%	68%

Less than a third of those aboard Titanic survived the disaster. Some survivors died shortly afterwards; injuries and the effects of exposure caused the deaths of several of those brought aboard Carpathia. Of the groups shown in the table, 49% of the children, 26% of the female passengers, 82% of the male passengers and 78% of the crew died. The figures show stark differences in the survival rates of the different classes aboard Titanic. Although only 3 percent of first-class women were lost, 54% of those in third class died. Similarly, five of six first-class and all second-class children survived, but 52 of the 79 in third class perished. The only first-class child to perish was Loraine Allison, aged 2. Proportionately, the heaviest losses were suffered by the second-class men, of whom 92% died. Additionally, among the pets brought aboard, three survived the sinking.
