After the partial conquest of Jing province in 208, followed by his defeat at the Red Cliffs, Cao Cao entered a period of several years’ intense and varied activity, leading military campaigns to the south and west while seeking at the same time to enhance his authority with an effective civil administration and a splendid court. Now in his mid- fifties, he displayed great energy in a complex political situation, even as uncertainty about his ultimate ambitions caused some advisers to flatter him and others to turn against him. From one month to the next, Cao Cao had to deal with different aspects of government, while his rivals to the south re-arranged their territories.

Sun Quan had sent a detachment under towards the Huai River, but this was turned back quite quickly, and his main effort was directed at Hefei. As the offensive was maintained through the first months of the year, Cao Cao became concerned and led his army to the southeast; for the time being Cao Ren had to be left to his own resources. By the third month, Cao Cao and the main body of his troops had reached Qiao county in Pei, still a considerable distance from Hefei, but Sun Quan was confused by a false report that relief was close at hand and was persuaded to withdraw.2 With the immediate danger past, Cao Cao moved more slowly, downstream to the Huai and then
