 According to Mary F. Somers Heidhues, during May and June 1945, some Japanese were killed in a rebellion by the Dayaks in Sanggau.According to Jamie S. Davidson, this rebellion, during which many Dayaks and Japanese were killed, occurred from April through August 1945, and was called the "Majang Desa War".The Pontianak Incidents, or Affairs, are divided into two Pontianak incidents by scholars, variously categorised according to mass killings and arrests, which occurred in several stages on different dates.
