USAT Dorchester

USAT Dorchester was a United States Army Transport, sunk when part of a naval convoy during World War II. In February 1943, Convoy SG-19 left St. John's, Newfoundland, bound for the Army Command Base at Narsarsuaq in southern Greenland. SG-19 consisted of six ships: Dorchester, two merchant ships leased by the United States from the Norwegian government-in-exile, D/S (Diesel Ship) Lutz, and D/S Biscaya. They were escorted by three small United States Coast Guard cutters: Comanche (WPG-76), Escanaba (WPG-77) (both 165 feet), and Tampa (WPG-48) (240 feet). On the night of 3 February 1943, the ship was torpedoed by U-223. The damage was severe, and Dorchester sunk in under 15 minutes, taking about 600 men with her out of a total crew of 902.

Dorchester is best remembered today for the story of the Four Chaplains who went down with her.
