“Since we cannot take Nanan, our next best plan is to try for Shanggui, which is the storehouse of Nanan.”
Leaving Xiahou Ba on the hill, Jiang Wei led a force of veteran soldiers and bold officers along the road toward Shanggui. They marched all night, and dawn found them in a deep valley, which the guides said was Block Valley.
“That sounds too much like 'Cut-off Valley,'“ said Jiang Wei. “And if a force held the mouth, we should be in sorry straits.”
While hesitating whether to advance farther or not, the leading troops came back to say they had seen a cloud of dust beyond the hills, which seemed to indicate a body of soldiers in hiding. So the order was given to retire.
At that moment the armies under Shi Zuan and Deng Zhong came out and attacked. Jiang Wei, alternately fighting and retreating, tried to get away. Then Deng Ai himself appeared, and the Shu army had enemies on three sides. They were in grave danger, but Xiahou Ba came to their rescue, and so Jiang Wei escaped.
Jiang Wei proposed to return to Qishan, but Xiahou Ba said, “We cannot go thither, for Chen Tai has destroyed the force under Bao Su, and he himself was killed. All that was left of that army has gone back into Hanzhong.”
It was no longer a question of taking the Dongting road. Jiang Wei sought out by-roads to march along. Deng Ai came in pursuit, and as he pressed hard on the rear, Jiang Wei sent the others on ahead while he covered the retreat.
Soon Chen Tai came out from the hills, and Jiang Wei was surrounded by a shouting body of the enemy. He fought all directions, but could not clear the way. He and his horse were very weary when Zhang Ni, who had heard of his straits, came to his rescue with a body of cavalry. Zhang Ni cut his way in, and Jiang Wei immediately broke the siege and got out. Zhang Ni saved his general, but lost his own life in the melee. Finally Jiang Wei got back into Hanzhong.
From Hanzhong the death of Zhang Ni in battle was reported to the Latter Ruler, who bestowed suitable honors upon his family. The Shu people blamed Jiang Wei for the serious loss of life of their relatives in the military operations that had just failed, and Jiang Wei, following the precedent in Jieting of the late Lord of Wuxiang, asked that he himself should be degraded in rank, retaining, however, the command. He was put back to General of the Rear Army.
The country being now cleared of the enemy, Chen Tai and Deng Ai prepared a banquet in honor of victory and gave rewards to the soldiers who had fought. Chen Tai sent a memorial to the capital upon the services of Deng Ai, and a special commission of Sima Zhao brought Deng Ai higher rank; the title of lordship was given to his son, Deng Zhong.
At this time the style of the reign in Wei was changed from Right Origin, the third year, to Gentle Dew, the first year (AD 256). Sima Zhao commanded all the military forces and made himself Empire Commander-in-Chief. He assumed great pomp, and whenever he moved outside his palace, he was escorted by three thousand mail-clad guards, beside squadrons of cavalry. All power lay in his hands, and he decided all questions so that the court was rather in his palace than in that of the Emperor.
Plans for taking the final step constantly occupied his thoughts. The question of mounting the throne was openly mooted by Jia Chong, a confidant, who was a son of Commander Jia Kui.
Jia Chong said, “Sir, all real authority is in your hands, and the country is not tranquil. The only remedy is for you to become actual ruler, and you should find out who are your supporters.”
Sima Zhao replied, “This has been in my thoughts a long time. You might be my emissary to the east to find out the feeling there. You can pretend you go to thank the soldiers who took part in the late campaign. That would be a good pretext.”
Accordingly Jia Chong traveled into the South of River Huai, where he saw Zhuge Dan, General Who Guards the East. This officer was from Nanyang and a cousin of the late Lord of Wuxiang, Zhuge Liang. Zhuge Dan had gone to Wei for employment, but had received no significant office while Zhuge Liang was the Prime minister of Shu. After Zhuge Liang's death, Zhuge Dan's promotion was rapid. He was now Lord of Gaoping and Commander of the south and east of River Huai.
Jia Chong went to Zhuge Dan to ask him to convey to the army the appreciation of the soldiers' services. Jia Chong was received courteously, and at a banquet, when host and guest were both mellow with wine, Jia Chong set himself to discover Zhuge Dan's feelings.
Jia Chong said, “Lately in Luoyang there has been much talk of the weakness and lack of ability of the Emperor and his unfitness to rule. Now General Sima Zhao comes of a family noted for state service for three generations. His own services and virtues are high as the heavens, and he is the man best fitted to take the rulership of Wei. Is this not your opinion?”
