USS Forsyth

After shakedown training in the Caribbean, Forsyth steamed north to Naval Station Argentia, Newfoundland, the base for her future operations as a weather ship. She departed Argentia on 2 April 1945 on her first weather patrol, reporting meteorological data, and maintaining readiness to aid any ship or aircraft in distress.

On 12 May 1945, Forsyth was called off her weather reporting station to search through haze and fog for the German submarine U-234, which wanted to surrender in the immediate aftermath of the surrender of Germany at the end of World War II in Europe. On 15 May 1945, Forsyth joined destroyer escort USS Sutton (DE-771) in accepting the surrender of U-234 in the Atlantic Ocean at 46°39′00″N 045°39′00″W. U-234 was carrying a German technical mission to Tokyo, Japan, which was still at war with the Allies, where the Germans expected to help the Japanese. Two Japanese officer passengers on board U-234 had previously committed suicide rather than surrender. Later on the day of the capture of U-234, Forsyth's medical officer, joined by the doctor from U-234, operated on board Forsyth on one of Sutton's men who had been wounded accidentally while collecting small arms on board the submarine. Forsyth carried the injured sailor into Argentia, arriving there on 18 May 1945. Despite the prompt treatment of the wound, internal hemorrhaging proved too severe, and the injured sailor died on 25 May 1945.

Forsyth continued her weather reporting duty in the North Atlantic Ocean for five more months. She then steamed south to Recife, Brazil, where she moored on 1 December 1945. Until 1 March 1946, she operated out of Recife on weather station duty.

On 8 March 1946, Forsyth departed Recife for Trinidad. At midnight on 14 March 1946, while at sea, she was decommissioned as a ship of the U.S. Navy
