During the Japanese invasion of Malaya in World War II, on 23 January 1942, after The Battle of Muar, a number of
Allied soldiers were killed by Japanese troops in what became known as the Parit Sulong Massacre. In this engagement, which commenced on January 14 with an Allied ambush of Japanese troops, the Allied troops managed to inflict heavy losses on the advancing Imperial Guard Division of the Japanese army. However, Allied positions were poorly defended, and could not be held. Attempts to hold the position near Parit Sulong bridge resulted in the deaths of two commanding officers and much of the 45 Division, which would cease to exist after its decimation by the Japanese. When the then-commanding officer, Lieutenant Colonel Charles Anderson, retreated after failing to receive both requested aerial support of bombings and morphine, fell back, the advancing Japanese slaughtered the wounded that had been left behind. Estimates of the number of killed range from 150 to 300. These were wounded soldiers, unable to retreat in the face of the advancing Japanese. This was only one of a number of atrocities carried out by the Japanese as they advanced through Malaya towards Singapore.
Allied records demonstrate that it was not merely Allied soldiers who suffered at the hands of the Japanese, and likely far more Chinese residents were killed outside of combat than Allied soldiers at this stage of the war, particularly if we take into account sook ching in Singapore. For example, about 200 Chinese are recorded being killed in one location alone. At least 280 Chinese are recorded killed. Locations of atrocities are provided below.by
