Meng Da
However, eight days later, when Sima Yi's army had arrived, Meng Da wrote to Zhuge Liang again, "I plotted a rebellion. Within eight days (Sima Yi)'s army has reached my city. What godspeed is that?" Meng Da was based in Shangyong (上庸), a city in Xincheng which was surrounded on three sides by water, so he set up wooden barriers to defend himself. Sima Yi's forces crossed the waters, destroyed the barriers, and arrived just outside Shangyong. Sima Yi then split up his army to attack Meng Da from eight directions. Sima Yi tempted Meng Da's nephew Deng Xian (鄧賢) and subordinate Li Fu (李輔) into surrendering, which they did so by opening Shangyong's gates after sixteen days of siege. Meng Da was captured and executed, and his head was sent to the Wei capital Luoyang.
