On January 23, 1942, the Parit Sulong Massacre 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. The Allies 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. Approximately 150 Australians and Indians were too badly injured to move, and their only option was surrender. Some accounts estimate that as many as 300 Allied troops were taken prisoner at Parit Sulong.
The wounded prisoners of war were kicked and beaten with rifle butts by the Imperial Guards. At least some were tied up with wire in the middle of the road, machine-gunned, had petrol poured over them, were set alight and (in the words of Russell Braddon) were "after their incineration — [were] 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, causing the rest to fall into the Simpang Kiri river and drown.
