In 1622, after another unsuccessful Dutch attack on Macau (trade post of Portugal from 1557) and the failure to set up a trading post in Fat Tong O (present day Hong Kong), the fleet sailed to the Pescadores, this time intentionally, and proceeded to set up a base there at Makung. They built a fort with forced labour recruited from the local Chinese population. Their oversight was reportedly so severe and rations so short that 1,300 of the 1,500 Chinese enslaved died in the process of construction. The same year a ship named the "Golden Lion" (Dutch: "Gouden Leeuw") was wrecked at Lamey just off the southwest coast of Formosa; the survivors were slaughtered by the native inhabitants. The following year, 1623, Dutch traders in search of an Asian base first arrived on the island, intending to use the island as a station for Dutch commerce with Japan and the coastal areas of China.
