呂蒙
Later, in 217, Cao Cao personally led a large army to invade Sun Quan's garrison at Ruxu (濡須; north of present-day Wuwei County, Anhui). Sun Quan led his forces to resist the enemy and placed Lü Meng in charge of the army. Lü Meng arrived at the dock, which was constructed earlier in 213, and stationed thousands of archers there to rain arrows on the enemy when they approached. He also attacked the camp of Cao Cao's vanguard force before the enemy established a foothold and succeeding in destroying the camp. Cao Cao saw that he could not overcome Sun Quan and eventually retreated. Lü Meng was promoted to General of Tiger's Might () and appointed as Left Protector of the Army ().
