Malayan Campaign - Retreat To Singapore

Retreat To Singapore

On 31 January, the last organised Allied forces left Malaya, and Allied engineers blew a 70 ft (21 m)-wide hole in the causeway that linked Johore and Singapore; a few stragglers would wade across over the next few days. Japanese raiders and infiltrators, often disguised as Singaporean civilians, began to cross the Straits of Johor in inflatable boats soon afterwards.

In less than two months, the Battle for Malaya had ended in comprehensive defeat for the Commonwealth forces and their retreat from the Malay Peninsula to the fortress of Singapore. Nearly 50,000 Commonwealth troops had been captured or killed during the battle. The Japanese Army invaded the island of Singapore on 7 February and completed their conquest of the island on 15 February, capturing 80,000 more prisoners out of the 85,000 allied defenders.

By the end of January, Patrick Heenan—British Indian Army captain convicted of treason, after spying for Japan—had been court-martialled and sentenced to death. On 13 February, five days after the invasion of Singapore Island, and with Japanese forces approaching the city centre, Heenan was taken by military police to the waterside and was hastily executed. His body was thrown into the sea.
