The Siege of Fort Zeelandia (Chinese: 安平城之圍; also known as the Siege of Anping) was a military confrontation that took place on the island of Taiwan from 23 March 1661 to 1 February 1662. The conflict pitted the forces of the Dutch East India Company (Vereenigde Oostindische Compagnie, VOC), which controlled the fortified settlement of Fort Zeelandia at present‑day Anping, Tainan, against the Ming loyalist and pirate leader Zheng Chenggong (commonly known as Koxinga).
Background
- In 1624 the VOC established a trading post and fortified settlement at Fort Zeelandia, marking the beginning of Dutch colonial rule in Taiwan.
- Following the collapse of the Ming dynasty and the establishment of the Qing dynasty in mainland China, Zheng Chenggong, a former Ming military commander who had taken refuge in the southern seas, sought to use Taiwan as a base for launching operations to restore Ming authority.
Course of the siege
- On 23 March 1661, Zheng Chenggong landed with an estimated 25,000–30,000 troops and a fleet of approximately 400 vessels at the southwestern coast of Taiwan.
- The Dutch garrison, commanded by Governor-General Frederick Coyett, numbered roughly 2,000 men, including European soldiers, Asian mercenaries, and local Taiwanese allies.
- Zheng's forces established a systematic blockade, constructing siege works, artillery batteries, and a network of trenches that encircled the fort.
- Over the ensuing months, both sides engaged in artillery exchanges, mining operations, and occasional sallies. The Dutch attempted to resupply the fort by sea, but Zheng’s naval superiority and control of surrounding waters limited these efforts.
- Disease, shortages of food and ammunition, and the psychological strain of the prolonged encirclement weakened the Dutch defenders.
Conclusion and aftermath
- On 1 February 1662, Governor Coyett surrendered Fort Zeelandia to Zheng Chenggong in exchange for safe passage for the remaining Dutch personnel and civilians.
- The capitulation marked the end of Dutch colonial rule in Taiwan; the VOC subsequently withdrew from the island, and Zheng established the Kingdom of Tungning (Zheng regime) as a Ming loyalist stronghold.
- The siege had broader regional implications, demonstrating the vulnerability of European colonial outposts in East Asia and contributing to the rise of Chinese maritime power in the mid‑17th century.
Historical significance
- The event is considered a decisive episode in the transition of Taiwan from European colonial control to Chinese administration.
- It is frequently studied as an example of early modern siege warfare in the Asian context and as a pivotal moment in the life of Koxinga, who is celebrated in Taiwanese, Chinese, and overseas Chinese historiography.
Key figures
- Zheng Chenggong (Koxinga) – Leader of the Chinese forces, commander of the siege.
