Deng Dun 鄧敦

In Chapter 115 of the Romance, following Xi Zheng's plan, Jiang Wei submitted a memorial to the Later Lord and went to Tazhong with 80,000 troops to plant wheat and set up military farms. When Deng Ai drew a map of the terrain there, where more than forty camps stretched along the road like a long snake, and sent it up, Sima Zhao, Duke of Jin, flew into a rage, saying that Jiang Wei repeatedly invaded the Central Plains and yet could not be wiped out, and was an affliction in his very heart and belly. Romance, Ch. 115 §28–31

Jia Chong proposed sending an assassin to stab Jiang Wei to death, but the Attendant Gentleman (congshi zhonglang) Xun Yi said that Liu Shan, the ruler of Shu, was sunk in wine and women and trusted Huang Hao, so that if a great general were sent to attack there was no way he could fail to win; he recommended Deng Ai and advised making Zhong Hui his deputy general. When Zhong Hui presented a map he had drawn in advance, Sima Zhao made Zhong Hui General Who Guards the West to command the forces of Guanzhong, and made Deng Ai General Who Conquers the West to command Longshang beyond the passes, and set a date for them to attack Shu. Romance, Ch. 115 §31–35

The next day, when Sima Zhao discussed the matter at court, the General of the Front Deng Dun said that Jiang Wei had repeatedly invaded the Central Plains and the troops had suffered very heavy losses, so that even holding the defenses could not now be guaranteed; why then push deep into a land of perilous mountains and rivers and bring disaster upon themselves? Sima Zhao, enraged, said that he meant to raise an army of humanity and righteousness to attack a lord without the Way and asked how Deng Dun dared go against his will, and he shouted at his guards to drag him out and behead him. Shortly afterwards Deng Dun's head was presented below the steps, and everyone turned pale. Romance, Ch. 115 §35–36

Sima Zhao said that since his campaign in the east he had rested for six years, training troops and repairing armor, and that he would first pacify Western Shu and then, riding the momentum of the downstream current, swallow up Eastern Wu as well. He then reckoned up the numbers of the Western Shu troops and set out his plan to have Deng Ai pin Jiang Wei down at Tazhong and have Zhong Hui attack Hanzhong by three routes, and everyone bowed in admiration. Zhong Hui set out with his army on the 3rd day of the 7th month, in autumn, of the 4th year of Jingyuan of Wei (263). Romance, Ch. 115 §36–38 · 40
