In February of 1943, the U.S. Army transport shipped Dorchester was packed with about 900 soldiers, sailors and civilian workers, sailing in a convoy from Newfoundland to an American base in Greenland.
At 12:55 a.m., a German U-boat put a torpedo into her side. The ship went down in 27 minutes, in freezing water, in the dark.
Four Army chaplains were aboard. They'd become friends at chaplains' school at Harvard the year before: George Fox, a Methodist minister; Alexander Goode, a rabbi; Clark Poling, a Reformed Church pastor; and John Washington, a Catholic priest. They calmed the men, handed out life jackets from the lockers, and when the jackets ran out, they took off their own and gave them to four young men.
Survivors in the water saw them on the tilting deck with their arms linked, praying together. Of roughly 900 aboard, about 230 survived.
I've always thought this should be taught in every school in America. Four men from four faiths, arms linked. Truman later dedicated a chapel in their honor, and today the Chapel of the Four Chaplains stands at the old Navy Yard in Philadelphia.
