Passage: She was occupied on Arctic convoys until hitting a mine off Iceland on 3 March 1942 and was under repair until July. After more Arctic convoys, Sheffield joined the forces supporting the Allied landings in North Africa (Operation Torch) in November. In December 1942, Sheffield and Jamaica formed "Force R", under the command of Rear-Admiral Robert Burnett (in Sheffield), which provided cover for Convoy JW 51B. The convoy was attacked by a strong German surface force. In the ensuing action (Battle of the Barents Sea), the Germans withdrew and Sheffield sank the German destroyer Friedrich Eckoldt, while also damaging the cruiser Admiral Hipper, Eckoldt mistaking Sheffield for Hipper. During this engagement, the destroyer Achates and the minesweeper Bramble were sunk by gunfire of the two German vessels.

Question: When was Sheffield occupied?
