Then Meng Da fled. But he was pursued, and as he and his horse were both exhausted, he was speedily overtaken and slain. They exposed his head, and his soldiers submitted. Sima Yi was welcomed at the open gates. The people were pacified, the soldiers were rewarded and, this done, a report of their success was sent to Cao Rui. Cao Rui ordered the body of Meng Da to be exposed in the market place of Luoyang, and he promoted Shen Yi and Shen Dan and gave them posts in the army of Sima Yi. He gave Li Fu and Deng Xian command of the cities of Xincheng and Shangyong.
Then Sima Yi marched to Changan and camped. The leader entered the city to have audience with his master, by whom he was most graciously received.
“Once I doubted you;” said Cao Rui, “but then I did not understand, and I listened to mischief-makers. I regret it. You have preserved both capitals by the punishment of this traitor.”
Sima Yi replied, “Shen Yi gave the information of the intended revolt and thought to memorialize Your Majesty. But there would have been a long delay, and so I did not await orders, but set forth at once. Delay would have played into Zhuge Liang's hands.”
Then Sima Yi handed in Zhuge Liang's letter to Meng Da, and when the Emperor had read that, he said, “You are wiser than both the great strategists of old — Wu Qi and Sun Zi.”
The Ruler of Wei conferred upon the successful leader a pair of golden axes and the privilege of taking action in important matters without first obtaining his master's sanction.
When the order was given to advance against the enemy, Sima Yi asked permission to name his leader of the van, and nominated Zhang He, General of the Left Army.
“Just the man I wished to send,” said Cao Rui, smiling. And Zhang He was appointed.
Sima Yi took his army off Changan and marched it to the camp of the Shu army.
The result of the campaign will appear in the next chapter.
Beside sending Zhang He as van-leader of Sima Yi, Cao Rui appointed two other generals, Xin Pi and Sun Li, to assist Cao Zhen. Xin Pi and Sun Li each led fifty thousand troops.
Sima Yi's army was two hundred thousand strong. They marched out through the pass and made a camp.
When encamped, Sima Yi summoned Zhang He to his tent and admonished him, saying, “A characteristic of Zhuge Liang is his most diligent carefulness; he is never hasty. If I were in his place, I should advance through the Ziwu Valley to capture Changan and so save much time. It is not that he is unskillful, but he fears lest that plan might miscarry, and he will not sport with risk. Therefore he will certainly come through the Xie Valley, taking Meicheng on the way. That place captured, he will divide his force into two, one part to take Chi Valley. I have sent Cao Zhen orders to guard Meicheng strictly and on no account to let its garrison go out to battle. The generals Sun Li and Xin Pi are to command the Chi Valley entrance, and should the enemy come, they are to make a sudden attack.”
“By what road will you advance?” asked Zhang He.
“I know a road west of Qinling Mountains called Jieting, on which stands the city Liliu. These two places are the throat of Hanzhong. Zhuge Liang will take advantage of the unpreparedness of Cao Zhen and will certainly come in by this way. You and I will go to Jieting, whence it is a short distance to Yangping Pass. When Zhuge Liang hears that the road through Jieting is blocked and his supplies cut off, he will know that Xizhou is impossible to keep, and will retire without losing a moment into Hanzhong. I shall smite him on the march, and I ought to gain a complete victory. If he should not retire, then I shall block all the smaller roads and so stop his supplies. A month's starvation will kill off the soldiers of Shu, and Zhuge Liang will be my prisoner.”
Zhang He took in the scheme and expressed his admiration, saying, “O Commander, your calculation exceeds human!”
Sima Yi continued, “However, it is not to be forgotten that Zhuge Liang is quite different from Meng Da; and you, as leader of the van, will have to advance with the utmost care. You must impress upon your generals the importance of reconnoitering a long way ahead and only advancing when they are sure there is no ambush. The least remissness will make you the victim of some ruse of the enemy.”
Zhang He, having received his instructions, marched away.
Meanwhile a spy had come to Zhuge Liang in Qishan with news of the destruction of Meng Da and the failure of his conspiracy.
