楊奉
After having Emperor Xian and the new central government firmly under his control, Cao Cao led his troops to attack Yang Feng in November 196 and defeated him. Xu Huang, one of Yang Feng's subordinates, surrendered and became a general under Cao Cao. While Yang Feng fled south to join the warlord Yuan Shu, Cao Cao proceeded to conquer Liang State (Yang Feng's previous base). After joining Yuan Shu, Yang Feng and Han Xian pillaged and looted several counties in Yang and Xu provinces.
