As part of this undertaking anti-submarine trawlers operated from the Hvalfjörður in south-western Iceland and Arkhangyel’sk in the USSR to act as rescue ships: four trawlers from Hvalfjördur were on patrol between 29 October and 14 November, and three trawlers from Arkhangyel’sk were on patrol between 1 and 6 November. Between 30 October and 17 November the trawlers were supplemented by two submarines from patrols off the coast of German-occupied Norway.
