U-654 under Ludwig Forster led the next patrol to the area, entering just south of Bermuda and taking the conventional route from Lorient to Panama via the Windward Passage. On the 10th of August the sub rounded the southern end of the Turks & Caicos Islands and the following day passed the northwest coast of Haiti to port and entered the Windward Passage southbound.
There were no Allied ships sunk on this patrol, which began on the 11th of July 1942 and was the 8th by U-654. While en route away from Europe the boat was vectored to convoy OS 34 along with other boats, but only U-564 succeeded in sinking ships before the subs were chased away by escorting aircraft.
U-654 was refueled west of the Azores by U-463 in late July. There would be no return voyage as the sub was sunk off Panama north of Colon on 22nd August by depth charges from a US B 18 bomber piloted by Lt. P. A. Koenig. All 44 hands were lost (Wynn, Vol. 1, p.111).
Oberleutnant zur See Ludwig Forster was a member of the Crew of 1936 who earned the Iron Cross Second Class in September 1939. Hit total tally was three ships sunk for 17,755 GRT and one warship sunk for 900 tons. He effected four war patrols in command of U-654 over 162 days in the First Flotilla out of Brest. He was 26 years of age when killed of Panama.
