On 23 January 1942, the Parit Sulong Massacre in Johor, Malaya (now Malaysia) was committed against Allied soldiers by members of the Imperial Guards Division of the Imperial Japanese Army. A few days earlier, the Allied troops had ambushed the Japanese near Gemas and blown up a bridge there.
During the Battle of Muar, members of both the Australian 8th Division and the 45th Indian Infantry Brigade were making a fighting withdrawal, when they became surrounded near the bridge at Parit Sulong. They fought the larger Japanese forces for two days, until they ran low on ammunition and food. Able-bodied soldiers were ordered to disperse into the jungle, the only way they could return to Allied lines. About 150 Australians and Indians were too seriously injured to move, and their only option was to surrender. Some accounts estimate that as many as 300 Allied troops were taken prisoner at Parit Sulong.
The Imperial Guards kicked and beat the wounded prisoners of war with their rifle butts. At least some of them were tied up with wire in the middle of the road and machine-gunned. The Japanese then poured petrol over the bodies, set them alight, and (in the words of Russell Braddon) "after their incineration...systematically run over, back and forwards, by Japanese driven trucks." Anecdotal accounts by local people also reported POWs being tied together with wire and forced to stand on a bridge, before a Japanese soldier shot one of them, causing the rest to fall into the Simpang Kiri river and drown.
Lt Ben Hackney of the Australian 2/29th Battalion feigned death and managed to escape. He crawled through the countryside for six weeks with two broken legs, before he was recaptured. Hackney survived internment in Japanese POW camps, and was part of the labour force on the notorious Burma Railway. He and two other survivors gave evidence regarding the massacre to Allied war crimes investigators.
