On the surface, Ouyang Shuo's target was Peng City, but in truth, it was the nearby Su County.
When Song Yi led the troops to save Zhao, West Conquering Army Commander Liu Bang was camping in Dang Prefecture.
Liu Bang sent out troops from the Dang Prefecture, going up north and clearing up the scattered troops of Chen Sheng and Xiang Liang. Then, he went down to attack the Qi Army, destroying Wang Li's forces.
The Wang Li forces around this area were just 150 thousand fringe members.
Following which, he led his troops through the west, where he met Peng Yue and Chang Yi.
The two of them joined hands to attack Chang Yi, but they failed. Liu Bang returned with his troops to Su County were he met the Gangwu Lord and took over his troops. As a result, he increased his numbers to over four thousand.
Hence, Ouyang Shuo needed to face a county with around six thousand troops. Although they did not have high numbers, Liu Bang had a flurry of famous generals by his side.
