That encounter took place roughly four days out, at about 11:30 p.m. on April 14. Titanic was equipped with a Marconi wireless, and there had been sporadic reports of ice from other ships, but she was sailing on calm seas under a moonless, clear sky. A lookout saw the iceberg dead ahead coming out of a slight haze, rang the warning bell and telephoned the bridge. The engines were quickly reversed and the ship was turned sharply, and instead of making direct impact the berg seemed to graze along the side of the ship, sprinkling ice fragments on the forward deck. Sensing no collision, the lookouts were relieved. They had no idea that the iceberg’s jagged underwater spur had slashed a 300-foot gash well below the ship’s waterline, and that Titanic was doomed. By the time the captain toured the damaged area with Harland and Wolff’s Thomas Andrews, five compartments were already filling with seawater, and the bow of the ship was alarmingly down. Andrews did a quick calculation and estimated that Titanic might remain afloat for an hour and a half, perhaps slightly more. At that point the captain, who had already instructed his wireless operator to call for help, ordered the lifeboats to be loaded.
A little more than an hour after contact with the iceberg, a largely disorganized and haphazard evacuation process began with the lowering of the first lifeboat. The craft was designed to hold 65 people; it left with only 28 aboard. Amid the confusion and chaos during the precious hours before Titanic plunged into the sea, nearly every boat would be launched woefully under-filled, some with only a handful of passengers. In compliance with the law of the sea, women and children boarded the boats first; only when there were no women or children nearby were men permitted to board. Yet many of the victims were in fact women and children, the result of disorderly procedures that failed to get them to the boats in the first place.
Exceeding Andrews’ prediction, Titanic stubbornly managed to stay afloat for close to three hours. Those hours witnessed acts of craven cowardice and extraordinary bravery. Hundreds of human dramas unfolded between the order to load the lifeboats and the ship’s final plunge: Men saw off wives and children, families were separated in the confusion and selfless individuals gave up their spots to remain with loved ones or allow a more vulnerable passenger to escape.

Only two of the 18 launched lifeboats rescued people after the ship sank. Lifeboat 4 was close by and picked up five people, two of whom later died. Close to an hour later, lifeboat 14 went back and rescued four people, one of whom died afterward. Other people managed to climb onto the lifeboats that floated off the deck. There were some arguments in some of the other lifeboats about going back, but many survivors were afraid of being swamped by people trying to climb into the lifeboat or being pulled down by the suction from the sinking Titanic, though it turned out that there had been very little suction.
As the ship fell into the depths, the two sections behaved very differently. The streamlined bow planed off approximately 2,000 feet below the surface and slowed somewhat, landing relatively gently. The stern plunged violently to the ocean floor, the hull being torn apart along the way from massive implosions cause by compression of the air still trapped inside. The stern smashed into the bottom at considerable speed, grinding the hull deep into the silt.
After steaming at 17.5 knots for just under four hours, RMS Carpathia arrived in the area and at 4:10 began rescuing survivors. By 8:30 she picked up the last lifeboat (only 706 people survived the sinking) and left the area at 8:50 bound for New York.
