Operation Tiderace

Battle context

Operation Tiderace was the British plan to retake Singapore following Japan's surrender in 1945, executed as part of the broader Allied effort to reassert control over Southeast Asia at the close of World War II. Led by Lord Louis Mountbatten as Supreme Allied Commander of South East Asia Command, the operation was coordinated alongside Operation Zipper, the concurrent liberation of Malaya. The near-total casualty figure recorded for the Japanese force of 77,000—with 76,700 accounted for—reflects the scale of the surrender and disarmament process rather than conventional combat. Tiderace marked the formal restoration of British authority over Singapore, a territory whose fall in 1942 had represented one of the most significant defeats in British imperial history.
