Pontianak is the capital of the Indonesia province of West Kalimantan. It is a medium-size industrial city located at , on the island of Borneo. It occupies an area of 107.82 km² in the delta of the Kapuas River, at approximately 1143 km, the longest river in Indonesia. It is located precisely on the equator.
During the Japanese occupation of 1942 to 1945, more than 21,000 people in Pontianak (including women and children) were kidnapped, tortured and massacred by Japanese troops. Japanese intelligence had become concerned ethnic Chinese were planning to start a rebellion, and were worried that people in the city had received guns and ammunition from the Chinese government.
After the end of war, the Japanese officers in Pontianak were arrested by allied troops and brought in front of an international military tribune. During the trial, it was revealed that the plan to start the rebellion did not exist and instead was only an imaginary plan created by Japanese officers who wanted to get promoted. The massacre occurred from April 23, 1943 to June 28, 1944 and most of the victims were buried in several giant wells in Mandor (88 km from Pontianak). Allied forces occupying the area after the war found several thousand bones, and more than 60 years after the massacre, several secret graves of the victims were found in Mandor and the surrounding areas.
A monument called Makam Juang Mandor was created to commemorate this tragic event.
