Singapore. Churchill gives General Wavell “discretion to cease resistance”, which Wavell passes on to Malaya commander General Percival. At 9.30 AM, Percival meets with senior military and civilian leaders. Low on ammunition, with dead and wounded piling up and no fresh water supply, they agree that further resistance is futile. Percival dispatches a delegation at 11.30 AM with a white flag and a Union Jack, following Japanese instructions, but they are sent back by the Japanese who want Percival to surrender in person. At 5.15 PM, Percival returns with the white flag and Union Jack to meet General Yamashita in the Ford Motor Factory at Bukit Timah. After 50 minutes of one-sided negotiations, Percival agrees to an 8.30 PM ceasefire and surrender. Japanese have 5092 casualties (1714 killed) but capture 500 mortars, artillery, anti-tank and anti-aircraft guns. 65,000 Indian, 35,000 British, 15,000 Australian and 15,000 Malay troops go into captivity, where many will die. Numerous Allied troops escape overnight on small boats including Australian General Gordon Bennett who will be reprimanded for not seeking permission from Percival, his superior officer. To impose order on the island, Japanese will slaughter 5000 Chinese civilians as an example.
