On 11 September, "Algonquin" formed part of the screening force for another strike against German shipping off Norway. Upon returning from this mission, the destroyer escorted convoys to Murmansk and back. Only two ships were torpedoed, both on the trip back to the United Kingdom. "Algonquin" escorted a British force from 14–15 October sent to perform air-mining and attacks on Axis shipping routes along the coast of Norway near Frohavet. From 26–28 October, "Algonquin" is among the escort for the aircraft carrier during attacks on Norway as part of Operation Athletic.
