Upon reaching Xiayi (下邑; east of present-day Dangshan County, Suzhou, Anhui), which was defended by his brother-in-law, Liu Bang reorganised his troops for a retreat. When he arrived at Yu (虞; present-day Yucheng County, Shangqiu, Henan), he sent an envoy to meet Ying Bu (King of Jiujiang) to appeal for support. Ying Bu, who held a grudge over Xiang Yu's unfair enfeoffment over the Eighteen Kingdoms, agreed to join Liu Bang and rebelled against Western Chu. Xiang Yu responded by sending Long Ju to attack Ying Bu.
