The Latter Ruler was overcome with great sorrow, and wailed, crying, “Heaven smites me!” and he fell over and lay upon his couch. They led him within to the inner chambers; and when Empress Wu, the Empress Dowager, heard the sad tidings, she also wailed without ceasing. And all the officers were distressed and wept, and the common people showed their grief.
The Latter Ruler was deeply affected, and for many days could hold no court. And while thus prostrate with grief, they told him that Wei Yan had sent up a memorial charging Yang Yi with rebellion. The astounded courtiers went to the Latter Ruler's chamber to talk over this thing, and Empress Wu was also there. The memorial was read aloud. It was much like this:
“I, thy Minister and General, Wei Yan, General Who Conquers the West and Lord of Nanzheng, humbly and with
bowed head write that Yang Yi has assumed command of the army and is in rebellion. He has made off with the coffin of the late Prime Minister and wishes to lead enemies within our borders. As a precaution, and to hinder his progress, I have burned the Plank Trail and now report these matters.”
The Latter Ruler said, “Wei Yan is a valiant warrior and could easily have overcome Yang Yi; why then did he destroy the Plank Trail?”
Empress Wu said, “The First Ruler used to say that Zhuge Liang knew that treachery lurked in the heart of Wei Yan, and he wished to put Wei Yan to death; he only spared Wei Yan because of his valor. We should not believe too readily this tale of his that Yang Yi has rebelled. Yang Yi is a scholar and a civil officer, and the late Prime Minister placed him in a position of great responsibility, thereby proving that he trusted and valued Yang Yi. If we believe this statement, surely Yang Yi will be forced to go over to Wei. Nothing should be done without due meditation.”
As they were discussing this matter, an urgent memorial came from Yang Yi, and opening it, they read:
“I, Yang Yi, leader of the retreating army, humbly and with trepidation, present this memorial. In his last moments the
late Prime Minister made over to me the charge of the great enterprise, and bade me carry out his plan without change. I have respected his charge. I ordered Wei Yan to command the rearguard with Jiang Wei as his second. But Wei Yan refused obedience and led away his own army into Hanzhong. Then he burned the Plank Trail, tried to steal away the body of the late Commander-in-Chief, and behaved altogether unseemly. His rebellion came upon me suddenly and unexpectedly. I send this memorial in haste.”
The Empress Dowager listened to the end. Then, turning to the officers, she said, “What is your opinion now?”
Jiang Wan replied, “Yang Yi is hasty and intolerant, but he has rendered great services in supplying the army. He has long been a trusted colleague of the late Prime Minister, who, being near his end, entrusted to him the conduct of affairs. Certainly he is no rebel. On the other hand, Wei Yan is bold and ambitious and thinks himself everybody's superior. Yang Yi is the only one who has openly been of different opinion, and hence Wei Yan hates him. When he saw Yang Yi placed over his head in command of the army, Wei Yan refused his support. Then Wei Yan burned the Plank Trail in order to cut off Yang Yi's retreat, and maligned him, hoping to bring about his fall. I am ready to guarantee Yang Yi's fealty to the extent of my whole house, but I would not answer for Wei Yan.”
Dong Yun followed, “Wei Yan has always been conceited and discontented. His mouth was full of hate and resentment, and only fear of the late Prime Minister held him in check. The Prime Minister's death gave him his opportunity, and he turned traitor. This is certainly the true state of the case. Yang Yi is able, and his employment by the late Prime Minister is proof of his loyalty.”
“If this is true and Wei Yan is really a rebel, what should be done?” asked the Latter Ruler.
“I think the late Prime Minister has framed some scheme by which to get rid of Wei Yan. If Yang Yi had not felt secure, he would scarcely have set out to return through the valleys. Your Majesty may feel sure that Wei Yan will fall into some trap. We have received, almost at the same time, two memorials from two men, each bringing against the other a charge of rebellion. Let us wait.”
Just then Fei Yi arrived. He was summoned into the royal presence and told the story of Wei Yan's revolt.
The Latter Ruler replied, “In that case I should do well to send Dong Yun with the flag of authority to mediate the situation and attempt to persuade Wei Yan with kind words.”
So Dong Yun left on this mission. At this time Wei Yan was camped at Nangu Valley, which was a commanding position. He thought his plan was succeeding well. It had not occurred to him that Yang Yi and Jiang Wei could get past him by any by-way.
On the other hand, Yang Yi, thinking that Hanzhong was lost, sent He Ping with three thousand troops on in front while he followed with the coffin.
When He Ping had got to the rear of Nangu Valley, they announced their presence with rolling drums. The scouts quickly told Wei Yan, who at once armed himself, took his sword, and rode out to confront He Ping. When both sides were arrayed, He Ping rode to the front and began to revile his opponent.
“Where is that rebel Wei Yan?” cried He Ping.
“You aided that traitor Yang Yi;” cried Wei Yan, no way backward with his tongue, “how dare you abuse me?”
He Ping waxed more indignant.
“You rebelled immediately after the late chief's death, before even his body was cold. How could you?”
Then shaking his whip at the followers of Wei Yan, He Ping cried, “And you soldiers are Shu people. Your fathers and mothers, wives and children, and your friends are still in the land. Were you treated unkindly that you have joined a traitor and aid his wicked schemes? You ought to have returned home and waited quietly the rewards that would have been yours.”
The soldiers were touched by his words; they cheered, and more than a half ran away.
Wei Yan was now raging. He whirled up his sword and galloped forward straight for He Ping, who went to meet him with his spear ready. They fought several bouts, and then He Ping rode away as if defeated. Wei Yan followed, but He Ping's troops began to shoot and Wei Yan was driven backward. As he got near his own ranks, Wei Yan saw many generals leaving their companies and going away. He rode after them and cut some of them down. But this did not stay the movement; they continued to go. The only steady portion of his own army was that commanded by Ma Dai. They stood their ground.
“Will you really help me?” said Wei Yan. “I will surely remember you in the day of success.”
The two then went in pursuit of He Ping, who fled before them. However, it was soon evident that He Ping was not to be overtaken, and the pursuers halted. Wei Yan mustered his now small force.
“What if we go over to Wei?” said Wei Yan.
“I think your words unwise,” said Ma Dai. “Why should we join anyone? A really strong person would try to carve out his own fortune and not be ready to crook the knee to another. You are able enough and brave enough to be more than a match for any leader in the Lands of Rivers. No one would dare to stand up to you. I pledge myself to go with you to the seizure of Hanzhong, and thence we will attack the Western Land of Rivers.”
So they marched together toward Nanzheng, where was Jiang Wei. From the bridge Jiang Wei saw their approach and marked their proud, martial look. He ordered the drawbridge to be raised and sent to tell his colleague, Yang Yi.
As they drew near, both Wei Yan and Ma Dai shouted out, “Surrender!”
In spite of the smallness of their following, Jiang Wei felt that Ma Dai acting with Wei Yan was a dangerous combination, and he wanted the advice of Yang Yi.
