[3] Group B-6 had sailed without the destroyers Fame and Viscount which had been damaged in the battle for eastbound convoy SC 104.

The United States Coast Guard cutters Bibb, Duane, and Ingham accompanied the convoy from the Western Approaches with ships that detached for Iceland on 15 November.

[4] As western Atlantic coastal convoys brought an end to the second happy time, Admiral Karl Dönitz, the Befehlshaber der U-Boote (BdU) or commander in chief of U-Boats, shifted focus to the mid-Atlantic to avoid aircraft patrols.

[7] When initial attempts to summon additional U-boats to the convoy were unsuccessful, U-521 was granted permission to attack, and missed with a salvo of six torpedoes.

[7] The U-boats had broken off the engagement by the time the four surviving corvettes were reinforced by the destroyers HMS Firedrake and USS Badger, and the Western Local Escort Force assumed responsibility for the convoy on 20 November.
