Republic of Formosa
The Republic of Formosa survived for only five months. The Japanese landed near Keelung on the northern coast of Taiwan on 29 May 1895, and in a five-month campaign swept southwards to Tainan. During the night of 4 June, on the news that the Japanese had captured Keelung, President T'ang and General Chiu fled to Tamsui, and from there sailed for the mainland on the evening of 6 June. The Japanese entered Taipei shortly afterwards.
Dutch pacification campaign on Formosa
The Dutch Pacification Campaign on Formosa was a series of military actions and diplomatic moves undertaken in 1635 and 1636 by Dutch colonial authorities in Dutch-era Taiwan (Formosa) aimed at subduing hostile aboriginal villages in the southwestern region of the island. Prior to the campaign the Dutch had been in Formosa for eleven years, but did not control much of the island beyond their principal fortress at Tayouan, and an alliance with the town of Sinkan. The other aboriginal villages in the area conducted numerous attacks on the Dutch and their allies, with the chief belligerents being the village of Mattau, who in 1629 ambushed and slaughtered a group of sixty Dutch soldiers.
