Battle of Java (1942)
The Battle of Java (Invasion of Java, Operation J) was a battle of the Pacific theatre of World War II. It occurred on the island of Java, between 28 February and 12 March 1942.
It involved forces from the Empire of Japan, which invaded on 28 February 1942, and Allied personnel. Allied commanders signed a formal surrender at Japanese headquarters at Bandung on 12 March.
Japan demanded the delivery of raw materials, most importantly OIL from Sumatra. The Dutch administration complied; yet in March 1942 the Japanese invaded, occupying most of the archipelago (southern New Guinea escaped Japanese occupation). The Dutch residents, in total 170,000, were INTERNED, a Japanese military administration established; the Japanese partitioned the archipelago in three zones, Sumatra, the Central and the Eastern Islands; many Indonesians found employment in the new administration. Dutch was replaced, as language of administration, education and jurisdiction, by Bahasa Indonesia and Japanese.
