The Taiwanese Army on Phú Quốc Island, also known as the Futai Army, is a term referring to a group of troops of the Republic of China that retreated from Guangxi Province to French-controlled Vietnam under the lead of Nationalist General Huang Chieh. In the PRC and North Vietnam they are called The remnants of Chiang's Bandit Army invading Vietnam. Later, French colonial forces, citing "protection", put the army under house arrest on Phú Quốc Island, hence the name they are referred to today. In 1953, with the help of the United States, it was negotiated that the Phú Quốc army would be transferred to Taiwan. After arrival, they were reorganized as part of the Republic of China Marine Corps. Background. After the failure of the Yangtze River Crossing campaign, many forces of the Republic of China fled to Taiwan or Hainan. However, many troops of Guangxi and Yunnan retreated to the south. In early July of 1949, PLA and Viet Minh forces attacked the modern-day Friendship Pass near the China-Vietnam border. Only 48 people escaped the encirclement and escaped to Vietnam, that was occupied by the French. The French army disarmed them there and concentrated them around Lạng Sơn. This marked the beginning of the ROC army's stay in Vietnam.
