The KNIL and its Ambonese auxiliaries have been accused of committing war crimes during this "police action". Dutch efforts to re-establish their colony failed and Netherlands recognition of Indonesian sovereignty came on 27 December 1949. On 26 January 1950, elements of the KNIL were involved in an abortive coup in Bandung planned by Raymond Westerling and Sultan Hamid II. The coup failed and only accelerated the dissolution of the federal Republic of the United States of Indonesia. The KNIL was disbanded by 26 July 1950 with its indigenous personnel being given the option of demobilising or joining the newly formed Indonesian military. However, efforts to integrate former KNIL units were impeded by mutual distrust between the predominantly Ambonese KNIL troops and the Javanese-dominated Republican military, leading to clashes at Makassar in April and the attempted secession of an independent Republic of South Maluku (RMS) in July. These revolts were suppressed by November 1950 and approximately 12,500 Ambonese KNIL personnel and their families opted for temporary resettlement in the Netherlands. Following this, the KNIL ceased to exist but its traditions are maintained by the Regiment Van Heutsz of the modern Royal Netherlands Army. At the time of disbandment the KNIL numbered 65,000, of whom 26,000 were incorporated into the new Indonesian Army. The remainder were either demobilised or transferred to the Royal Netherlands Army. Recruiting During its formation, it was stated that the KNIL would include both European and indigenous soldiers. In the beginning the KNIL was equally divided, which meant that half the army consisted of European soldiers, while the other half was made up of indigenous soldiers. However, starting from the late 1830s the ratio between European soldiers and indigenous soldiers went from 1:1 to 1:3. The reason for this was that there were not enough European volunteers to keep up with the recruitment of indigenous soldiers. Besides European volunteers and indigenous recruits the KNIL also recruited foreign mercenaries of several nationalities during the 19th century. During the protracted Aceh War the numbers of European troops were kept to 12,000 but continued Achenese resistance necessitated the deployment of up to 23,000 indigenous soldiers (mainly from Java, Ambon, and Manado). Even slaves of the Ashanti (Ivory Coast and Ghana) were recruited in
