launch the attack." Sun Quan followed Lü Meng's suggestion and commissioned Lu Xun as a Lieutenant-General () and Inspector of the Right Section () to replace Lü Meng in Jing Province. When Lu Xun arrived at Lukou (陸口; at Lushui Lake near present-day Chibi, Hubei) to assume his new office, he wrote to Guan Yu to flatter him: Later, after Guan Yu defeated Yu Jin at the Battle of Fancheng, Lu Xun wrote a letter to Guan again to flatter him and put him off guard: Invasion and pacification of Jing Province Upon receiving the letters, Guan Yu saw that Lu Xun showed humility and expressed his desire to rely on him, so he felt at ease and lowered his guard. When Lu Xun heard about it, he wrote a report to Sun Quan and provided crucial details on how to defeat Guan Yu. Sun Quan secretly sent an army to invade Jing Province, with Lü Meng and Lu Xun leading the vanguard force.

Li Yi led the naval forces while Xie Jing commanded the land army. They sealed the critical routes and defeated
