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.
Formosa Expedition
The Formosa Expedition, or the Taiwan Expedition of 1867 was a punitive expedition launched by the United States against Formosa. The expedition was undertaken in retaliation for the Rover incident, in which the "Rover", an American bark, had been wrecked and its crew massacred by aboriginal Paiwan warriors in March 1867. A United States Navy and Marine company landed in southern Formosa and attempted to advance into the native village. The natives deployed a significant amount of guerrilla warfare, which they ambushed, skirmished, disengaged and retreated repeatedly. Eventually, the Marines ceased their pursuit when their commander was killed and retreated back to their ship due to fatigue and heat exhaustion, with the Formosans dispersing and retreating back into the jungle. The event is regarded as a failure in United States naval history, as the expedition did not decisively defeat the Formosans.
