Sun Quan turned to the aborigines of the southeast, whom the Chinese collectively called the "Shanyue". A collection of successes against the rebellious tribesmen culminated in the victory of 224. In that year, Zhuge Ke ended a three-year siege of Danyang with the surrender of 100,000 Shanyue. Of these, 40,000 were drafted as auxiliaries into the Wu army. Meanwhile, Shu was also experiencing troubles with the indigenous tribes of their south. The southwestern Nanman peoples rose in revolt against Shu authority, captured and looted cities in Yi Province. Zhuge Liang, recognizing the importance of stability in the south, ordered the advance of the Shu armies in three columns against the Nanman. He fought a number of engagements against the chieftain Meng Huo, at the end of which Meng Huo submitted. A tribesman was allowed to reside at the Shu capital Chengdu as an official and the Nanman formed their own battalions within the Shu army.
