On 8 June, "Swenning" rescued eight members of the RAF whose Halifax bomber had been ditched in the ocean. The task group arrived at Bermuda on 30 June and departed the next day for Norfolk where it was dissolved. The escorts continued to New York, and "Swenning" was given an overhaul. She returned to Norfolk on 22 July to rejoin the "Bogue" group (TG 22.3) which sortied three days later. After a short training period at Bermuda, the group began offensive patrols in the North Atlantic, mainly off the Grand Banks area of Newfoundland. On 19 August, "Bogue" aircraft attacked a surfaced submarine. Damage was not ascertained as the submarine submerged. The following day another was attacked on the surface. It also submerged; but, approximately two and one-half hours later, it surfaced; the crew abandoned it; and the submarine sank shortly thereafter. The ships replenished at Argentia on 24 August and resumed operations until 24 September when the group was dissolved at New York. After a yard period and refresher training in the New London, Connecticut, area, "Swenning" sailed to Norfolk.
