It was the evening of Feb. 2, 1943, and the U.S.A.T. Dorchester was crowded to capacity, carrying 902 service men, merchant seamen and civilian workers.

Once a luxury coastal liner, the 5,649-ton vessel had been converted into an Army transport ship. The Dorchester, one of three ships in the SG-19 convoy, was moving steadily across the icy waters from Newfoundland toward an American base in Greenland. SG-19 was escorted by Coast Guard Cutters Tampa, Escanaba and Comanche.

Hans J. Danielsen, the ship's captain, was concerned and cautious. Earlier the Tampa had detected a submarine with its sonar. Danielsen knew he was in dangerous waters even before he got the alarming information. German U-boats were constantly prowling these vital sea lanes, and several ships had already been blasted and sunk.

The Dorchester was now only 150 miles from its destination, but the captain ordered the men to sleep in their clothing and keep life jackets on. Many soldiers sleeping deep in the ship's hold disregarded the order because of the engine's heat. Others ignored it because the life jackets were uncomfortable.

On Feb. 3, at 12:55 a.m., a periscope broke the chilly Atlantic waters. Through the cross hairs, an officer aboard the German submarine U-223 spotted the Dorchester.
The U-223 approached the convoy on the surface, and after identifying and targeting the ship, he gave orders to fire the torpedoes, a fan of three were fired. The one that hit was decisive--and deadly--striking the starboard side, amid ship, far below the water line.

Danielsen, alerted that the Dorchester was taking water rapidly and sinking, gave the order to abandon ship. In less than 20 minutes, the Dorchester would slip beneath the Atlantic's icy waters.
