    SC-528's Official Coast Guard History

S., escorting four trawlers. On August 5, 1942, she departed Sydney for Greenland escorting 3 vessels with 4 other escorts arriving on the 10th. On the 11th she proceeded to Bluie West Seven and assumed guardship duties off entrance to Kungnat Bay. On August 27th she proceeded to Holstenborg to inspect Portuguese fishing vessels en route to Helfiske Bay, returning to BW No. 8 on the 31st. During September 1942 she was engaged in local escort duty between Greenland stations. She reassumed guardship duties at the junction of Brede and Skov Fjords on October 9, 1942, but was forced to return to BW No. 1 because of heavy waters and ice. On the 21st she want to the assistance of the disabled freighter MARGARET LYKES and escorted her to Marrak Point where she assumed guardship duties, departing for BW No. 1 on the 22nd. During November and December, 1942, the SC-528 was on guardship at the entrance to Arsuk Fjord, being relieved periodically, when she usually escorted incoming vessels to BW No. 7.

Standing out of Boston on that day the FALCON [ASR-2] collided with the SC-527 on the 15th. The USS PINTO [AT-90] in convoy lost her tow and the SC-528 screened her until it was recovered, mooring at Argentia with
    SC-707 to rendezvous with two other escorts to accompany three vessels to Argentia where she remained until the 31st. After further local escort duty at Argentia the SC-528 stood out on the 5th with three other escorts arriving at St. John's on the 6th and from there escorting convoy SG-29 with 6 other escorts to Kungnat Bay, mooring at BW No. 7 on the 21st. The SC-528 continued on patrol and local escort duty in Greenland waters until the end of 1943.

    The SC-528 remained on patrol duty in Greenland waters until July 25, 1944. During that period she broke ice in the fjords and relieved the SC-527 and
    SC-688 on sound and radar watches on anti-submarine patrol at the entrance of Arsuk Fjord. January 11, 1944 her propeller was damaged by ice varying in thickness to 2 feet in South Entrance, Force Bay and Kungnat Bay. During February 1944 she was engaged in transportation duty between Navy 26 and BW No. 7. On July 25, 1944, she sailed for Argentia in company with COMANCHE [WPG-76], SC-527, and SC-704 and proceeded on to Boston with the latter two and USS KAWEAH [AO-15] where on August 6, 1944, she detached from Task Group 24.8 and was assigned to Commander, Service Force, U.
