The chapel honors four chaplins that perished with the U.S.A.T. Dorchester, which went down in the North Atlantic under submarine attack in 1943. Of the 902 passengers on board the ship, only 230 survived. It was the largest loss of life on a troop carrier during WWII. The Four Chaplains, of varying faiths, gave away their own life jackets, and then linked arms and sang and prayed for all those aboard while the ship sank into the icy waters.
