The following is part 3 of a condensed version (with footnotes omitted) of “African and Japanese Mercenaries in Southern China and Southeast Asia, c. 1550-1650” by Richard Bradshaw, in Kokujin Kenkyu 76 (April 2007), published by the Japan Black Studies Association.
The Dutch also employed both African and Japanese mercenaries who often fought together. In 1608, Japanese mercenaries helped the Dutch East India Company fight the Portuguese in the Spice Islands. In 1613 the Netherlands East India Company ships leaving Hirado transported Japanese adventurers to Java. Hendrik Broewer, chief of the Hirado factory, recorded that 68 Japanese left Hirado in February 1613 but that there was not enough room on the ship for the 300 Japanese requested by Dutch Governor General Both. Of the 68 Japanese sent, 9 were carpenters, 3 smiths, and 2 or 3 plasterers, but 51 were sailors and soldiers. In 1615, the Dutch signed a contract to obtain 59 Japanese, of whom 7 were carpenters and 2 were grooms, but 50 were sailors and soldiers.
After laying the foundation for the city of Batavia in 1619, Governor General Coen repeatedly asked the chief of the factory at Hirado to send as many Japanese as possible. By January 1620, 71 Japanese soldiers had arrived and Gov.-Gen. Coen took took 87 Japanese soldiers with him when he attacked the Bandanese in 1621. By this time the total number of Japanese residents at Batavia – including women, children and slaves – was certainly over 100, but many Japanese mercenaries were soon sent to Amboina and other places so that by 1622 the number of Japanese mercenaries in Batavia decreased to 30 while their numbers elsewhere in the Dutch East Indies were growing. Additional Japanese and African residents of Batavia arrived when the Dutch captured Portuguese ships. In 1637, 13 Japanese prisoners from a Portuguese junk captured off the island of Bintan arrived at Batavia, for example, where they obviously encountered Africans.
One Japanese mercenary, Anthony Japon, appears in records as a mardijker or soldier. In 1652 he was a sergeant of the black citizens (swarte borgerije). He is listed as an ensign by 1653 and as a lieutenant by 1655, but he was also a slave trader and a money-lending. Another resident, Michiel Itchiemon of Osaka, was Captain of the Japanese residents in 1626 and his son, Domingo Itchiemon, was a mardjiker soldier.
In 1622 Japanese and African mercenaries fought together and against each other when the Dutch attacked Macao. In 1621 the Dutch learned that the Ming rulers of China had asked the Portuguese of Macao to provide them with 100 mercenaries and cannon to fight the Manchus. The Dutch concluded that this left Macao vulnerable and so eight ships with multicultural crews, including Africans, were sent to attack Macao. Along their way the Dutch encountered a Siamese warship with twenty Japanese sailor-soldiers who had fled Portuguese service and now offered their services as mercenaries to the Dutch.
When the Dutch fleet reached Macao on 22 June 1622 with about 600 Europeans and 200 sailor-soldiers from Japan, Africa and elsewhere, they found themselves confronted with eight Europeans who commanded numerous African and Chinese soldiers. Some accounts state that the African defenders were slaves armed by their masters, but others suggest that Guinean mercenaries helped to defend the Portuguese port. In any case, African soldiers, whether slaves fighting for their freedom or Guinean mercenaries (or both), were crucial to the successful defense of Macao in 1622 against the Dutch and their Japanese and other mercenaries.
In 1623 the Dutch beheaded 10 Englishmen, 10 Japanese mercenaries and a Portuguese overseer of slaves at the English East India enclave on Amboina. The justification for this famous “massacre of Amboina” was that a Japanese mercenary arrested by the Dutch on suspicion of spying in February 1623 confessed under torture to a plot by English factors, aided by Japanese mercenaries, to attack the Dutch and seize Fort Victoria. There were “about thirty” Japanese mercenaries “regularly employed by the [Amboina] castle authorities” at this time. Some of the slaves overseen by the unfortunate Portuguese overseer who was beheaded were probably Africans, which puts Japanese and Africans together on Amboina at this time.
