陳誠
In the beginning of 1949, as the Republic of China government was retreating to Taiwan in the final stages of the Chinese Civil War, the Command was re-designated as "Taiwan Provincial Garrison Command" and headed by Chen Cheng, who concurrently held the office of Governor of Taiwan. On 20 May 1949, Chen Cheng, in his capacity as commanding general for the province and its military governor, declared martial law in Taiwan. Immediately, the Taiwan Provincial Garrison Command was ordered to enforce Martial Law within Taiwan, excluding the areas Kinmen and Matsu of Fujian Province, which had been under Martial Law since 10 December 1948.
