Operation Portcullis (1–5 December 1942) was the dispatch of Convoy MW 14 to Malta from Port Said. The convoy followed the success of Operation Stoneage (16–20 November) which had raised the Siege of Malta. Four merchant ships were escorted to Malta by seven destroyers of the 12th Destroyer Flotilla, supported by three cruisers of the 15th Cruiser Squadron and three destroyers from Alexandria.
