sent Han to lead reinforcements to help Liu Bang. Han Xin defeated Chu forces in the Battle of Jingsuo and drove them east of Xingyang. Northern campaign In late 205 BC, Liu Bang put Han Xin in command of an army and sent him to conquer the rival kingdoms in northern China. Han Xin's first target was Western Wei, ruled by Wei Bao, who defected to Xiang Yu's side after initially surrendering to Liu Bang. Han Xin tricked Wei forces into cornering themselves at the border and made a surprise attack on Anyi (present-day Xia County, Shanxi) with another force, scoring victory and capturing Wei Bao in battle. Shortly later, Han Xin proceeded to conquer the Dai kingdom and captured Dai's chancellor, Xia Shuo. Han Xin's army advanced further to attack the Zhao kingdom. He scored another tactical victory against the 200,000 strong Zhao army with a smaller force in the Battle of Jingxing. After his victory, Han Xin sent a messenger to Zang Tu (King of Yan) asking for his surrender, and Zang Tu agreed to submit to Liu Bang.

Han Xin later sent a messenger to Liu Bang, requesting that Liu appoint him as the acting King of Qi. At that time, Liu Bang was trapped in Xingyang by Xiang
