Battle of Hefei (208)

In the winter of 208–209, Cao Cao was defeated by Sun Quan and Liu Bei at the Battle of Red Cliffs, but he still had a large army garrisoned at the northern part of Jing Province (covering present-day Hubei and Hunan). The following month, Sun Quan's general Zhou Yu led an attack on Jiangling (江陵; located in present-day Jingjiang 荆江, not to be confused with Jiangling County, Hubei), which was defended by Cao Cao's cousin Cao Ren.

At the same time, Sun Quan personally led an assault on Cao Cao's fortress at Hefei, which was defended by Liu Fu, in an attempt to open two war fronts in the west and north. Sun Quan also sent Zhang Zhao to attack Dangtu (當塗), Jiujiang (九江) commandery, but was unsuccessful.

When Cao Cao heard news of the attack, he sent Zhang Xi (張喜) to lead an army to reinforce Hefei. The battle dragged on until the following year, but Sun Quan's forces were unable to breach Hefei. Sun Quan intended to personally lead a light cavalry contingent on a charge at the enemy, but Zhang Hong advised him against it, "Using the military is an offensive move, battles are dangerous. Now that our army's morale is high, if we suddenly launch a fierce attack, the troops will be disappointed. Even though it is possible to slay enemy generals, capture their flags and instil fear in them, this is a mission to be carried out by a subordinate general, and not the commander-in-chief. I hope you can control your zeal and courage, and possess the strategies of a conqueror-king."^[1] Sun Quan heeded Zhang Hong's advice and aborted his plan.

As Hefei had been constantly under attack for several months, compounded by heavy rain, the fortress' walls were starting to collapse, so Liu Fu ordered his men to use straw and palm leaves to cover up cracks in the walls. At night, Liu Fu had torches lit to brighten the scene outside Hefei, so he could observe the enemy's movements and prepare defences. Zhang Xi's relief force had yet to arrive, and Liu Fu was at a loss on how to resist the enemy. Liu Fu's deputy Jiang Ji suggested using a strategy to deceive the enemy that Hefei's reinforcements had arrived: spread false news that Zhang Xi's 40,000 strong relief army had reached Yulou (雩婁); send an official to pretend to receive Zhang Xi; send three officers to bring fake letters out of Hefei. Only one of the three officers returned to the fortress as the other two were captured by Sun Quan's men, who found the letters on them. Sun Quan read the letters and thought that Zhang Xi's reinforcements had indeed arrived, so he ordered his troops to burn down the camp and hastily retreat.
