The Qing forces were crushed by Wu from 1673 to 1674. The Qing had the support of the majority of Han Chinese soldiers and Han elite against the Three Feudatories, since they refused to join Wu Sangui in the revolt, while the Eight Banners and Manchu officers fared poorly against Wu Sangui, so the Qing responded with using a massive army of more than 900,000 Han (non-Banner) instead of the Eight Banners, to fight and crush the Three Feudatories. Wu Sangui's forces were crushed by the Green Standard Army, made out of defected Ming soldiers. In the Three Feudatories rebellion, Han bannermen who stayed on the Qing side and died in battle were categorized as martyrs.
