However, in the Battle of Fei River, Jin forces prevailed over the much larger Qin army, causing the collapse of Former Qin in the North. Taking advantage of this, Jin forces under first Xie An and then Liu Yu launched a series of expeditions that retook much of China's territory south of the Yellow River, the traditional heartland. Eventually, though, the Jin were overthrown by Liu Yu in 420, ending the dynasty.
