Eight Banners and Manchu officers fared poorly against Wu's forces, so the Qing responded with a massive army of more than 900,000 non-Banner Han Chinese, instead of the Eight Banners, to subdue the rebels. Wu Sangui's forces were crushed by the Green Standard Army, which was made up of defected Ming soldiers. During the Revolt of the Three Feudatories, Manchu Generals and Bannermen were initially put to shame by the better performance of the Han Chinese Green Standard Army, which was noted by the Kangxi Emperor, leading him to task generals Sun Sike, Wang Jinbao, and Zhao Liangdong with leading Green Standard Soldiers to put down the rebellion. The Qing considered the Han Chinese to be superior fighters, so used the Green Standard Army, rather than Bannermen, as the main force in defeating the rebels. Against Wang Fuchen in north-western China, the Qing put Bannermen in the rear as reserves. They used Han Chinese Green Standard Army soldiers and Han Chinese generals, such as Zhang Liangdong, Wang Jinbao, and Zhang Yong, as the primary military forces, and they achieved victory over the rebels. Sichuan and southern Shaanxi were retaken in 1680 by the Han Chinese Green Standard Army under Wang Jinbao and Zhao Liangdong, with Manchus only dealing with logistics and provisions. Four hundred thousand Green Standard Army soldiers and 150,000 Bannermen served on the Qing side during the war. Two hundred and thirteen Han Chinese Banner companies, and 527 companies of Mongol and Manchu Banners were mobilized by the Qing during the revolt. Reform and decline Reform of the Qing military system by the Kangxi Emperor during the last years of the War of the Three Feudatories led to a fundamental division of military administration and function between two branches of the Qing Army. The Eight Banners of the old Banner system were retained as a guard force for the dynasty, but Chinese and Mongol troops were progressively transferred out during the 18th century, until most Banner troops were once again ethnic Manchus. The Qing divided the command structure of the Green Standard Army in the provinces between the high-ranking officers and low-ranking officers. The best and strongest unit was under the control of the highest-ranking officers but, at the same time, those units were outnumbered by other units, which were divided between various lower-ranking officers, so that none of them could initiate a revolt on their own against
