Biography

He Bin was a Hokkien Chinese merchant and interpreter who served both the Dutch East India Company and the Zheng commercial network in the mid-seventeenth century, and whose 1659 defection helped enable Koxinga's eventual conquest of Dutch Taiwan. He came from a southern Fujian merchant family with established commercial ties to the Penghu and Tayouan trade circuit, and arrived in Dutch Formosa as a young man during the period of consolidated VOC rule in the 1640s. He prospered as a Hokkien interpreter and tax farmer for the VOC, taking advantage of his cultural and linguistic bridging role between the Dutch administration and the rapidly growing Hokkien settler and trader community. He simultaneously maintained covert commercial relations with the Zheng family's maritime network across the strait, exploiting the licit and illicit channels of the Sino-Japanese trade that flowed through Dutch Tayouan. By the late 1650s his finances had collapsed under the weight of borrowing from the VOC tax authorities and competing creditors, and warrants for his arrest were issued by the Dutch administration. In 1659 he fled Tayouan by sea and made his way to Xiamen, where he sought refuge in the court of Koxinga, who was at the time considering a fallback base on Taiwan after his failed mainland campaign against the Qing. He presented Koxinga with detailed sketches and maps of the Tayouan harbor and Fort Zeelandia, including descriptions of the channels through the sandbars, the placement of artillery, and the disposition of the small VOC garrison. He argued forcefully that Taiwan was a rich, lightly defended prize whose loyal Hokkien settlers would welcome Zheng forces, encouraging the warlord to redirect his strategic ambitions from the mainland coast to the island. His intelligence was central to the operational planning of Koxinga's 1661 amphibious crossing, including the decision to land at Lakjemuyse Bay through a channel often considered unnavigable by the Dutch. He accompanied the Zheng fleet on the crossing and served as a senior advisor and Hokkien-Dutch interpreter during the nine-month siege of Fort Zeelandia. His role in the post-conquest Tungning regime is poorly documented, and contemporary Dutch sources record only that he survived the campaign and continued in some capacity in the new administration. He Bin is generally remembered as the indispensable insider whose firsthand knowledge of Dutch defenses provided the operational basis for Koxinga's gamble on Taiwan and thereby the end of the VOC's thirty-eight-year rule.
