During World War II, Operation Zipper was a British plan to capture either Port Swettenham or Port Dickson, Malaya as staging areas for the recapture of Singapore in Operation Mailfist. 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. The planned deception for this attack was called Operation Slippery, whilst a small Special Operations Executive team led by Tun Ibrahim Ismail which landed in October 1944 managed to convince the Japanese that the landings were to be on the Isthmus of Kra, 650 miles (1,050 km) to the north.
