In Kumasi, a recruiting branch office was established by Jacob Huydecoper, a Dutch government official from Elmina of mixed Dutch-African descent. Kwaku Dua also sent two princes, Kwasi Boachi and Kwame Poku Boachi, to Verveer in the Netherlands for training. Their subsequent careers are described by Arthur Japin in his novel "The Two Hearts of Kwasi Boachi" (1997). Because the British had abolished slavery, a somewhat cautious approach to recruitment was taken. The Ashanti king offered slaves and prisoners of war from the surrounding regions, for Dutch colonial service. However they nominally put themselves forward as voluntary recruits. As Dutch military service personnel they were entitled to receive pay. However British objections in 1842 led to discontinuation of this relatively successful recruitment. In 1855 enrollment resumed due to the positive experiences of West African soldiers in the Dutch East Indies. This renewed recruitment was now on a strictly voluntary basis. A total of several thousand African soldiers "with a Dutch name", were shipped to the Dutch East Indies. The Treaty of Sumatra in 1871 gave the Netherlands possessions on the Gold Coast to the British. This terminated the recruitment of Africans for the Royal Netherlands East Indies Army. On April 20, 1872 the last ship with African recruits left for Java. There were however two further attempts to recruit black volunteers for the Colonial Army. Between 1876 and 1879 thirty American black recruits were hired for the KNIL. In 1890 there was an attempt to obtain recruits from Liberia. A total of 189 Liberians went to Java, but this group became almost entirely dissatisfied with failed promises and returned to Liberia in 1892. Even without the recruitment of African soldiers, the KNIL still had soldiers of African origin in its army long after the 1890s. These African and Indo-African soldiers were the offspring of the Africans that the Dutch shipped from the Dutch Gold Coast between 1830 and 1872.
