Operation Zipper was a British plan to capture either at Port Swettenham or Port Dickson, Malaya as staging areas   for the recapture of Singapore. However, due to the end of the war in the Pacific, it was never fully executed. Some of the proposed landings on Penang went ahead as planned to probe Japanese intentions, encountering no resistance.

British Forces were lead by the battleship HMS Nelson and RFA support was provided by RFA’s Dewdale (1), Easedale and Ennerdale (1)
