USS Forsyth was a United States Navy in commission from 1945 to 1946, which saw service in the final months of World War II and the first months of the postwar period. After her Navy career concluded, she was in commission in the United States Coast Guard as the cutterUSCGC Forsyth from March to August 1946. In 1947 she was sold to the Government of the Netherlands, for which she served as the civilian weather shipSS Cumulus from 1947 to 1963.
After shakedown training in the Caribbean, Forsyth steamed north to Naval Station Argentia, Newfoundland, the base for her future operations as a weathership. 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 GermansubmarineU-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 in accepting the surrender of U-234 in the Atlantic Ocean at. 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, Forsyths medical officer, joined by the doctor from U-234, operated on board Forsyth on one of Suttons 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.
Postwar
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
U.S. Coast Guard service
Immediately upon decommissioning at sea, Forsyth was commissioned into the United States Coast Guard as the cutter USCGC Forsyth. She steamed from Trinidad to Boston, Massachusetts, arriving there on 23 March 1945, and made one more North Atlantic patrol on ocean weather station duty. She then proceeded to New Orleans, Louisiana, where the Coast Guard decommissioned her on 2 August 1946 and transferred her back to the U.S. Navy.
Disposal
The U.S. Navy transferred Forsyth to the Maritime Commission for disposal. The Maritime Commission sold her to the Netherlands in 1947.
