Yang Liang
Yang Liang made initial gains, and his forces, commanded by Pei Wen'an (), quickly captured the strategically important Pu Province (蒲州, roughly modern Yuncheng, Shanxi) and were poised to cross the Yellow River to attack the capital region. For reasons unclear then, Yang Liang changed his mind and destroyed the bridge over the Yellow River, stalling his own advances, although he soon advanced south from Taiyuan himself to again make another offensive. Soon, Yang Su, loyal to Emperor Yang, advanced north and met Yang Liang's forces. Against Wang's suggestion that he should engage Yang Su quickly, Yang Liang withdrew to Qingyuan (清源, near Taiyuan), thus losing initiative. Yang Su defeated him and captured Xiao Mohe, forcing him to retreat back to Taiyuan, where Yang Su put him under siege. Wang Kui committed suicide. Eventually, Yang Liang surrendered. Even though officials largely suggested that Yang Liang should be executed, Emperor Yang did not do so, but reduced him to commoner rank and put him under imprisonment. He died in imprisonment, and although it was unclear the year he died, it appeared to be not long after his capture. His son Yang Hao (楊顥, different person than Yang Jun's son who later was declared emperor) was also imprisoned, and when Emperor Yang was assassinated by the general Yuwen Huaji in 618, Yang Hao was also killed.
