Order of battle After the nationalist offensive in the southern front had been defeated by the advance communist, Bai Chongxi ordered the nationalist III Corps and XI Corps to immediately retreat.

To boost morale, the nationalist commander-in-chief Zhang Gan (张淦) decided to be the last to retreat and his III Corps headquarters remained behind in the town of Bobai (博白), but this was detected by the attack communists in the afternoon of December 30, 1949.
