He struggled on till he and his steed were almost spent with fatigue. Presently he saw another company of the enemy in his way, and the leader was Jiang Wei. Before he could make any resistance, Jiang Wei's spear thrust him down, and as Xu Zhi lay on the ground he was cut to pieces.
Meanwhile those troops of Wei who had been sent to escort to camp the convoy of supplies which they had seized were captured by Xiahou Ba. They surrendered. Xiahou Ba then stripped them of their weapons and clothing and therein disguised some of his own soldiers. Holding aloft banners of Wei, these disguised soldiers made for the Wei camp. When they arrived, they were mistaken by those in the camp for comrades, and the gates were thrown open. They rushed in and began to slay. Taken wholly by surprise, Sima Zhao leaped upon his steed and fled. But Liao Hua met him and drove him back. Then appeared Jiang Wei in the path of retreat, so that no road lay open. Sima Zhao made off for the hills, hoping to be able to hold out on the Iron Cage Mountain.
Now there was only one road up the hill, which rose steeply on all sides. And the hill had but one small spring of water, enough to serve a hundred people or so, while Sima Zhao's force numbered six thousand. Their enemies had blocked the only road of escape. This one fountain was unequal to supplying the needs of the beleaguered army, and soon they were tormented with thirst.
In despair, Sima Zhao looked up to heaven and sighed, saying, “Death will surely come to me here!”
In this critical situation a certain civil officer, Wang Tao by name, reminded his leader of what Geng Gong had done in ancient time, saying, “O General, why do you not imitate Geng Gong, who, being in great need, prostrated himself and prayed at a well, wherefrom he afterwards was supplied with sweet water?”
So the leader went to the summit of the hill and knelt beside the spring and grayed thus:
“The humble Sima Zhao received a command to repulse the army of Shu. If he is to die here, then may this spring cease its flow, when he will end his own life and let his soldiers yield to the enemy. But if his allotted span of life be not reached, then, O Blue Vault, increase the flow of water and save the lives of this multitude.”
Thus he prayed; and the waters gushed forth in plenty, so that they all quenched their thirst and lived.
Jiang Wei had surrounded the hill, holding the army thereon as in a prison. He said to his officers, “I have always regretted that our great Prime Minister was unable to capture Sima Yi in the Gourd Valley, but now I think his son is doomed to fall into our hands.”
However, news of the dangerous position of Sima Zhao had come to Guo Huai, who set about a rescue.
Chen Tai said to him, “Jiang Wei has made a league with the Qiangs, and they have arrived to help him. If you go away to rescue Sima Zhao, the Qiangs will attack from the rear. Therefore I would propose to send some one to the tribespeople to try to create a diversion and get them to retire. If they are disposed of, you may go to the rescue of Sima Zhao.”
Guo Huai saw there was much reason in this, and told Chen Tai to take a force of five thousand troops and go to the camp of the King of the Qiangs. When Chen Tai reached the camp, he threw off his armor and entered weeping and crying that he was in danger of death.
He said, “Guo Huai sets himself up as superior to everyone and is trying to slay me. Therefore I have come to offer my services to you. I know all the secrets of the Wei army, and, if you will, this very night I can lead you to their camp. I have friends in the camp to help, and you can destroy it.”
King Mi Dang was taken with the scheme, and sent his General Ehe Shaoge to go with Chen Tai. The deserters from Wei were placed in the rear, but Chen Tai himself rode with the leading body of the Qiangs. They set out at the second watch and soon arrived. They found the gates open, and Chen Tai rode in boldly. But when Ehe Shaoge and his troops galloped in, there suddenly arose a great cry as soldiers and horses went tumbling into great pits. At the same time Chen Tai came round in the rear and attacked, while Guo Huai appeared on the flank. The Qiangs trampled each other down, and many were killed. Those who escaped death surrendered, and the leader, Ehe Shaoge, committed suicide in a pit.
