Internees: prisoners of war; men Number of internees: 90 (approximately) Information: From the end of 1942, the male population of the Kai Islands between the ages of 15 and 45 years old were pressed into work on various military projects. Because the native population was too small to complete these projects, Indonesian - mainly Moluccan - prisoners of war in camps in Java were pressed into service as heihos and put onto transports. Some of these prisoners of war were put to work for a period of three months at a Japanese base in Watidal, which was regularly a target of Allied bombers.
