Operation Sunfish was a military operation by Allied troops in April 1945. It involved the battleships HMS Queen Elizabeth and French battleship Richelieu. Their aircraft carried out a photo reconnaissance sweep of the area around Port Swettenham, 200 miles north of Singapore, on 14–16 April, before concluding the raid with an attack on Emmahaven (northern Sumatra) and Padang.^[1] It had its origins in the proposed Operation Sounder.^[2]
