After he became the commander of the Taiwan Defense Command in 1949, he put effort in planning and executing the defense plan of Penghu and Taiwan, as well as consolidating the army forces that evacuated to Taiwan.
However, Sun who was well respected by the Americans and graduated from the Virginia Military Institute earned the enmity of Chiang Kai-shek followed by the change of the China–United States relations. Sun was put under house arrest in 1955 for more than three decades. He was not released until March 20, 1988, shortly after the death of Chiang Ching-kuo.
