 The original communist plan of attacking on December 20, 1950 was forced to be carried out early on December 13, 1950 when the intelligence revealed that the nationalists planned to withdrew to Vietnam.After three days of travel, the communists succeeded in besieging the nationalist within the Chinese border.The nationalists attempt a futile breakout by sending out a small force to sneak out of the encirclement and cross the border, but the entire 80 member strong force was annihilated by the communist regiment of the Longzhou Military Sub-District in the region to the north of Jiute (九特).
