Gong'an County
Lü Meng wrote to the administrators of the three commanderies to ask them to submit to Sun Quan. They all agreed except Lingling's administrator, Hao Pu (). Liu Bei returned to Jing Province when he heard of Lü Meng's advances and garrisoned troops at Gong'an County while ordering Guan Yu to lead an army to take back the three commanderies. At the time, Sun Quan was at Lukou (陸口; at Lushui Lake near present-day Chibi, Hubei) and he sent Lu Su to lead 10,000 troops to Yiyang to block Guan Yu. Sun Quan also sent an urgent order to Lü Meng, ordering him to give up on Lingling and lead his troops to Yiyang to assist Lu Su.
