Li Dian
After the Battle of Jiangling in 209, Cao Cao left Li Dian, Zhang Liao and Yue Jin to defend Hefei, a strategic location at the border between Cao Cao and Sun Quan's territories. Around 214, when Sun Quan led his forces to attack Hefei, Zhang Liao wanted to lead their troops out of the city to resist the enemy. However, Zhang Liao was aware that the three of them could not get along with each other and he was worried that they would not comply with his orders. Zhang Liao said, "Our lord is away at war. By the time his reinforcements reach here, we're already done for. So he's actually instructing us to take advantage of the situation, when the enemy has just arrived and not fully gathered yet, to attack them and devastate their morale so as to calm our men and strengthen our defences. Victory or defeat, it all depends on this battle. Why are the two of you still hesitating?" Li Dian was moved and he said, "This is a national crisis. We'll see how your strategy works out. How can I allow my personal issues take precedence over my official duties?" Zhang Liao, Li Dian and Yue Jin then worked together and succeeded in defeating and driving away Sun Quan's much larger army. Li Dian was rewarded with an additional 100 taxable households in his marquisate, bringing the total number of households to 300.
