The map is courtesy of Graham DonaldsonBali Island was originally not a target in the Netherlands East Indies Campaign, but as the airfields on Borneo (Bandjermasin) were inoperative due to heavy rains and considering the fact that Bali Island didn't have that kind of rainfall, it was soon decided by the Imperial Japanese Army to occupy the island. They decided to send the Kanemura Detachment, one infantry battalion of 48th Japanese Infantry Division (Major-General Yuitsu Tsuchihashi) under command of Major Matabei Kanemura in order to capture Bali Island. The island had no regular KNIL troops. There was only a Native Auxiliary Corps Prajoda (Korps Prajoda) consisting of about 600 native soldiers and several Dutch KNIL officers under command of KNIL Lieutenant Colonel W.P. Roodenburg. Their main mission was to defend and/or to destroy Den Passar airfield in case of enemy attack. On 19 February 1942 the Japanese forces landed near the town of Senoer, Bali Island, advancing in the darkness of night and squall. They made a surprise attack on the Dutch barracks and occupied them with a little resistance. The airfield was also easily occupied. The Native Auxiliary Corps Prajoda immediately fell apart. Meeting no resistance, the Japanese secured the Den Passar airfield by 10:30 p.m. on the 19th February. Surprisingly the airfield had not been blown up. The order of the Dutch commander, Lieutenant Colonel W.P. Roodenburg, not to delay demolition was misread by the engineers on the airfield, who thought he wanted the operation delayed, so the airfield fell into Japanese hands completely intact. Early in the next day the men and planes of the Tainan Air Group arrived on the island.
Note Major-General G.A. Ilgen not only commanded the 3rd KNIL Division/III Military District, but was officially also the commander of the Native Auxiliary Corps Prajoda on Bali Island. The assistant commander (the one who did all the work) was KNIL Lieutenant Colonel W.P. Roodenburg, who was the senior officer on Bali Island when the Japanese invaded the island, February 1942.
