Therese andThetford Mines and Joliette were sent to patrol in the Shetland-Faroes narrows, off Hebrides, in the Irish Sea west of Ireland and in St. George's Channel.

[8] On 7 March 1945, La Hulloise took part alongside Strathadam and Thetford Mines, in the sinking of U-1302 in St George's Channel.

In August, La Hulloise and Crescent returned to Europe on a training cruise, with the frigate joining Magnificent in November when the aircraft carrier sailed to Norfolk, Virginia to embark Sea Furies.
