The "Titanic" sank early on April 15, 1912, at around 2:20 a.m., after striking an iceberg at around 11:40 p.m. Brown helped others board the lifeboats but was finally persuaded to leave the ship in Lifeboat No. 6. Brown was later called "The Unsinkable Molly Brown" by authors because she helped in the ship's evacuation, taking an oar herself in her lifeboat and urging that the lifeboat go back and save more people. Her urgings were met with opposition from Quartermaster Robert Hichens, the crewman in charge of Lifeboat 6. Hichens was fearful that if they went back, the lifeboat would either be pulled down due to suction or the people in the water would swamp the boat in an effort to get in. After several attempts to urge Hichens to turn back, Brown threatened to throw the crewman overboard. Sources vary as to whether the boat went back and if they found anyone alive. Brown's efforts sealed her place in history, regardless.
