USAT Dorchester

:"See USS Dorchester for commissioned United States Navy warships of this name."USAT "Dorchester" was a United States Army Transport ship that was sunk when it was 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 (SS "Lutz" and SS "Biscaya") that were leased by the United States from the Norwegian government-in-exile, and their escorts, the small United States Coast Guard cutters "Comanche", "Escanaba" (both 165 feet), and "Tampa" (240 feet).

On the night of 3 February 1943, "Dorchester" was torpedoed by German U-boat "U-223". The damage was severe, boiler power was lost, there was inadequate steam to sound the full 6-whistle signal to abandon ship, and "Dorchester" sank by the bow in about 20 minutes. Loss of power prevented sending a radio distress signal, and no rockets or flares were launched to alert the escorts. A severe list prevented launch of some port side lifeboats, and some lifeboats capsized through overcrowding. Survivors in the water were so stiff from cold they could not even grasp the cargo nets on rescue vessels. The crew of the "Escanaba" employed a new "retriever" rescue technique whereby swimmers clad in wet suits swam to victims in the water and secured a line to them so they could be hauled onto the ship. By this method, "Escanaba" saved 133 men (one died later) and "Comanche" saved 97 men of the 904 aboard Dorcester.

Life jackets offered little protection from hypothermia which killed most men in the water. Water temperature was convert|34|°F|°C and air temperature was convert|36|°F|°C. When additional rescue ships arrived on 4 February "...hundreds of dead bodies were seen floating on the water, kept up by their life jackets."

"Dorchester" is best remembered today for the story of the Four Chaplains who went down with her. In 1948 the US Postal Service issued a stamp to commemorate the sinking.
