to send aid. Sima Xin escaped from Zhao Gao's assassins on his return journey and reported to Zhang Han that the state power of Qin had fallen into the hands of Zhao. Zhang Han pondered over the situation and realised that he would not survive even if he attained victory over Xiang Yu, as Zhao Gao would have him killed on false charges of treason. Hence, Zhang Han and his 200,000 troops then surrendered to Xiang Yu and Zhang was conferred the title of "King of Yong" (雍王) by Xiang. After the fall of the Qin Dynasty in 206 BC, Xiang Yu divided the former Qin Empire into the Eighteen Kingdoms, while Zhang Han and his two deputies were granted the region of Guanzhong as their fiefs. The three kingdoms were known as the Three Qins because they occupied the lands of the former Qin state. Later that year, the forces of Liu Bang (King of Han) invaded Guanzhong and captured Zhang Han's territory in a surprise attack. Zhang Han retreated to Feiqiu (廢丘; present-day Xingping, Shaanxi) and remained there. A year later, in July 205 BC, the Han army flooded Feiqiu and Zhang Han committed suicide after his defeat.
