That year, Su Jun marched south from Linhuai to join Emperor Ming of Jin's loyalist coalition against the rebel Wang Dun.
Su Jun's men had only arrived and were exhausted from marching, which prompted Wang Dun's commanders, Qian Feng and Shen Chong, to attack them immediately.
Wang Dao was sent to stop him, but just before he could act, Su Jun had already sent Han Huang to help Zu Yue repel Shi Cong.
Su Jun's first course of action was to capture Jin's food supply at Gushu (姑孰, in present-day Dangtu County, Anhui).
Han Huang fought with Huan Yi's general Yu Zong (俞縱) at Lanshi (蘭石, in present-day Xuancheng, Anhui).
[5] Han Huang was in the midst of taking Daye (大業, in present-day Suzhou, Jiangsu) when news of Su Jun's death reached him in November.
Han Huang and the others decided to lead Su Yi and his remaining forces to Qu'a (曲阿, in present-day Suzhou, Jiangsu) to join Zhang Jian (張健).
Zhang Jian and the rest of the rebel leaders were afraid to come down from the mountain, but Han Huang personally went out with two quivers of arrows and sat on a chair.
