The Four Chaplains, also sometimes referred to as the "Immortal Chaplains," were four United States Army chaplains who gave their lives to save other civilian and military personnel during the sinking of the troop ship USAT Dorchester on February 3, 1943, during World War II. They helped other soldiers board lifeboats and gave up their own life jackets when the supply ran out. The chaplains joined arms, said prayers, and sang hymns as they went down with the ship.
