On departure the convoy was escorted by the light cruiser HMS Birmingham (Capt. H.W. Williams, RN) (actually joined on the 16th), sloops HMS Pelican (Cdr. J.S.

In the afternoon of 19 November, HMS Birmingham fuelled HMS Spey as the frigate had two out of four fuel tanks contaminated with seawater drastically effecting her range. With this underway refuelling she was able to continue on to Algiers.

During the morning of 20 November, the frigate HMS Rother also received some fuel from HMS Birmingham.

On passing the Straits of Gibraltar, HMS Birmingham parted company with the convoy and entered Gibraltar harbour. The AA cruiser HMS Colombo (Capt. D.H.

They were escorted by the destroyer escorts USS Frederick C. Davis (Lt.Cdr. O.W. Goepner, USNR), USS Herbert C. Jones (T/Lt.Cdr. A.W. Gardes, Jr., USN) and the minesweepers USS Pioneer (Lt. L.E. Rogers, Jr., USNR) and USS Portent (Lt. H.C. Plummer, USNR).
