The Battle of Liaoluo Bay took place in 1633 off the coast of Fujian, China; involving the Dutch East India Company (VOC) and the Chinese Ming dynasty's navies. The battle was fought at the crescent-shaped Liaoluo Bay that forms the southern coast of the island of Kinmen. A Dutch fleet under Admiral Hans Putmans was attempting to control shipping in the Taiwan Strait, while the southern Fujian sea traffic and trade was protected by a fleet under Brigadier General Zheng Zhilong. This was the largest naval encounter between Chinese and European forces before the Opium Wars two hundred years later.
