Anthonius Hambroek was a Christian minister on Taiwan, who fatefully became embroiled in the negotiations between the besieged Europeans in Fort Zeelandia, and the Chinese who surrounded them. In a moment celebrated in paintings and plays, he returned to deliver bad news to the “pirate king” Koxinga, sure in the knowledge that he would be executed. Despite his daughters’ pleading, he went back to Koxinga and was never seen alive again. Later on, his daughters were among the Dutch girls handed out to Koxinga’s men as part of the spoils of war – one of them allegedly serving briefly as Koxinga’s own bedmate.

Pastor Hambroek’s sacrifice was one of the most iconic moments in the siege of Fort Zeelandia, an event already riddled with high drama and cinematic spectacle. It’s also become the lynchpin of many a fictional account, beginning with a Dutch stage play by Johannes Nomsz, Anthonius Hambroek, or the Siege of Fort Zeelandia (1775).

Its most recent manifestation in popular culture is as the background to Yao-cheng Chen’s historical novel A Tale of Three Tribes in Dutch Formosa. Before he turned to fiction in his long retirement, Chen was a pioneering Taiwanese specialist in bone marrow transplants – a background that surprisingly produces one of the most gripping passages in his book. On hearing that one of the legendary ancestors of his own clan was a Dutch woman, he counts the incidences of ankylosing spondylitis (a type of arthritis), and determines that 4% of modern Taiwanese have a north European ancestor somewhere in their genes.

This is what inspired him to write his story, which comes deeply invested in the interlocking politics and tensions of the Dutch, Chinese and indigenous Formosans in the 17th century. They are, supposedly all given equal weight, although that Hambroek girl inevitably takes centre stage.

Who was she? In Nomsz’s play her name was Cornelia. In Joyce Bergveldt’s novel Lord of Formosa, her name is Johanna. In Chen’s book, her name is Christina, although her fate is kept discreetly off-stage, and instead we focus on her sister Maria, who may, or may not be, Chen’s own distant ancestor.

Chen realises that there’s a whole rack of Iliad allegories to be had, with a long siege, a vainglorious enemy and even a last-ditch hoped pinned on a ship called the Hector. His heroine, Maria Hambroek, archly observes that she is a bit like Cassandra, the seer cursed to always be ignored. I would suggest that there might have been more poetic currency to be had with her similarity to Briseis, the captive concubine whose fate is deeply entwined with that of the heroes.

One of the most compelling elements of the story of Koxinga’s invasion of Taiwan, for me at least, is the treatment of the Dutch women, a number of which were parcelled out among the Chinese. Modern authors seems to shy away from what this might have really meant; Bergveldt concocts a subplot in which Koxinga merely pretends to ravish a Hambroek girl as part of a bigger scheme; Chen is delicately coy about the sexual politics at play here, limiting himself to mentioning a few inter-racial “marriages”. Contemporary documentation, however, is considerably more forthcoming about it, particularly Frederik Coyett’s Neglected Formosa (1675), in which he mentions a number of Dutch girls returned pregnant to the East India Company at the final hostage exchange, as well as their widely varying reports of their treatment at the hands of the Chinese.

Dutch girls handed to soldiers who already had Chinese wives were often put to work as skivvies and slaves, complaining about months of hard labour under fierce mistresses. But this is where Chen’s Mills & Boon romanticism finds a legitimate purchase, since Coyett also reported that the Dutch girls who found themselves berthed with unmarried soldiers were “considerably caressed” and “did not complain too loudly, despite having half a Chinese in their belly.” He adds, in an arch footnote, that: “Those who had been kept honest by the ugliness of their faces, those were the women who were the loudest of all and who accused their companions of whoring and merry-making with the Chinese.”

I don’t know what really happened to that Hambroek girl. But I bet she had a story to tell.
