Siege of Fort Zeelandia

The **Siege of Fort Zeelandia** is the name for Koxinga's Invasion of Taiwan. The siege started in 1661 and ended in 1662. It ended the Dutch East India Company's rule over Taiwan. After the siege, the Kingdom of Tungning ruled over the island. This event was said to be "a war that determined the fate of Taiwan in the four hundred years".

## Beginning

In 1659, after an unsuccessful attempt to capture Nanjing, Koxinga, leader of Ming loyalists began searching for a home for his men.

_He Bin_, who was working for the Dutch East India Company, fled to Koxinga's base in Xiamen and provided Koxinga with a map of Taiwan. The Dutch had established a post at Tayoan, that had two forts.  The first was Fort Zeelandia at the entrance to the bay at Tayoan which was the main Dutch settlement. The second was Fort Provintia also located at the bay. Frederick Coyett, the governor of Taiwan was at Fort Zeelandia with 1,800 men. Fort Provintia had 500 men.

## The Siege

Koxinga's fleet set sail from Kinmen on March 23, 1661. His fleet consisted of hundreds of ships of various sizes, with 25,000 men aboard. The fleet arrived at Tayoan on April 2, and, after passing through a shallow waterway unknown to the Dutch, landed at Luermen.

The men laid siege to Fort Provintia and it surrendered on April 4. Three days after the capture of Fort Provintia, Koxinga's men surrounded Fort Zeelandia and demanded its surrender. Koxinga sent a Dutch priest, Anthonius Hambroek, to ask for this surrender. Hambroek did not do this and he was killed after returning to Koxinga's camp.

Koxinga's fleet then used cannons and they attempted to enter the fort, but many died. Koxinga then waited outside the fort. On May 28, news of Koxinga's attack reached Jakarta. The Dutch sent 10 ships and 700 sailors to help. The ships arrived on July 5 and had some small fights with Koxinga's fleet.

On July 23, the two sides fought as the Dutch ships tried to enter the fort. After a while, the Dutch ships had to retreat with two ships lost, three small vessels captured, and about a hundred casualties. The Dutch tried to break the siege again in October but were beaten back by Koxinga's army. This victory, coupled with news of low morale among the garrison from deserted German mercenaries, convinced Koxinga to launch an assault in December.

On January 12, 1662, Koxinga's fleet began another bombardment, while the ground forces prepared to assault the fort. With supplies dwindling and no sign of reinforcement, Coyett raised a white flag. The surrender was complete on February 1, and the Dutch East India Company left Taiwan on February 17.

## Afterwards

Coyett was tried for surrendering and exiled to the Banda Islands. He was pardoned after help from his friends. He published a book named _Neglected Formosa_ () in 1675. In the book, he criticized the company for neglecting his pleas for reinforcement.

After the loss of Tayoan, the Dutch East India Company tried to recapture it. They joined with the Qing Empire to battle Koxinga's fleet, but failed.

## Cultural influences

The battle was shown in the movie _Zheng Chenggong 1661_, which ends with Koxinga's victory over the Dutch. The movie's English title is _Sino-Dutch War 1661_.
