limited numbers for service in the East Indies (see Belanda Hitam). The ratio of foreign and indigenous troops to those of Dutch origin was reported to be 60% to 40%. After the Aceh War, the enlistment of non-Dutch European troops ceased and the KNIL came to consist of Dutch regulars recruited in the Netherlands itself, Indonesians, Indos (Eurasians), and Dutch colonists living in the East Indies and undertaking their military service. In 1884 personnel strength was numbered at 13,492 European, 14,982 Indonesian, 96 African (though some sources put the number of Africans much higher ) and at least 1,666 Eurasian recruits. The officer corps was wholly European and was probably close to 1,300. There were also about 1,300 horses. Recruitment was carried out in the Netherlands and Indonesia, with over 1,000 Dutch subjects and 500 foreigners enlisting annually. The foreign troops consisted of Flemish, German, Swiss, and French volunteers. Walloons, Arabs, and nationals of both the United Kingdom and United States were forbidden from serving. Other foreigners who could not prove fluency in either Dutch or German were also not accepted for service. It was against the law to send Dutch conscripts from the Netherlands to the East Indies but Dutch volunteers continued to enlist for colonial service in the KNIL. In 1890 a Corps Colonial Reserve (Koloniale Reserve) was established in the Netherlands itself to recruit and train these volunteers and to re-integrate them into Dutch society upon the conclusion of their overseas service. On the eve of the Japanese invasion in December 1941, Dutch regular troops in the East Indies consisted of about 1,000 officers and 34,000 men, of whom 28,000 were indigenous. The largest proportion of these "native troops" had always consisted of Javanese and Sundanese soldiers. During the Japanese occupation, most of the Dutch and Ambonese personnel were interned in POW camps. During the Indonesian National Revolution, the KNIL's officers were still largely Dutch and Eurasians although most of its troops were recruited from predominantly Indonesian Christian ethnicities, particularly Batak, Moluccas, Timor and Manado. Although there were smaller numbers of Javanese, Sundanese, Sumatran and other Muslim troops in Dutch service, these received comparatively lower rates of pay than their Christian counterparts, leading to resentment and distrust. The Dutch sought to take advantage of these ethnic tensions by claiming that the Ambonese would lose their special privileges and pensions under a Javanese-dominated government. As noted above, these
