Zhuge Liang's small carriage was escorted by only a few horsemen. Hearing that a sluggish river, the Western River, lay in the way, and having no boat, Zhuge Liang bade the escort cut down some trees and make a raft. They did so, but the raft sank. So Zhuge Liang turned to Lu Kai, who said, “There is close by a mountain covered with bamboos. I have heard of these bamboos, and some are several spans in girth. We can make a bridge of them for the army to cross.”
So thirty thousand soldiers were sent to the mountains, where they cut down many thousands of bamboos, and floated them down river. Then at the narrowest point they made a bridge a hundred spans or so in length. Next the main army was brought down to the river and camped in line along the bank. The camp was protected by a moat, crossed by a floating bridge, and a mud rampart. On the south bank they constructed three large stockades so as to prepare for the coming of the Mang soldiers.
They had not long to wait. Meng Huo was hot with rage and came quickly. As soon as he got near the river, he led out ten thousand fierce warriors, armed with big swords and shield, and challenged the first stockade.
Zhuge Liang went forth in simple state. He wore a silk cap and a crane-white robe and held in his hand a feather fan. He sat in a four-horse carriage, and his generals rode right and left.
The King of the Mang was clad in mail of rhinoceros hide and wore a bright red casque. In his left hand he bore a shield, and his right gripped a sword. He rode a red ox. As soon as he saw his enemies, he opened his mouth and poured forth abuse and insults, while his warriors darted to and fro brandishing their weapons.
Zhuge Liang at once ordered the army to retire within the stockades and bar the gates. The Mangs came close up to the stockade and pranced about naked, shouting in derision.
Within the stockade the Shu generals grew very angry, and they went in a body to their leader to beg that he would withdraw the order to remain on the defensive. But Zhuge Liang would not listen.
Presently he said, “These men are not submissive to the Empire Government and are naturally fierce and turbulent. In that mood we are no match for them. But all we have to do is to remain on guard for a few days till their ferocity has spent itself. Then I have a plan that will overcome them.”
Days passed, and the army of Shu made no move; they only maintained the defensive. Zhuge Liang watched the besiegers from an eminence, and saw the first vigor of their advance give way to careless idleness.
Then Zhuge Liang called together his generals and asked, “Dare you give battle now?”
They all rejoiced at the suggestion; so he called them two by two or one by one and gave them secret orders. Zhao Yun and Wei Yan went in first. Wang Ping and Ma Zhong followed. To Ma Dai he said, “I am going to abandon these stockades and retire north of the river. As soon as we have crossed, you are to cut loose the floating bridge and move it down the stream so that Zhao Yun and Wei Yan may cross.”
To Zhang Yi he said, “You are to remain by the camp and light it up at night — as if it is still occupied. When Meng Huo pursues, then you are to cut off his retreat.”
Last of all, Guan Suo was to escort Zhuge Liang's carriage.
The soldiers marched out of the camp at evening, and the lamps were hung up as usual. The Mangs saw this from a distance and dared not attack. But the next morning at dawn Meng Huo led his troops to the stockades and found all was quiet. He went close up and saw they were all empty and bare; not a soldier was there. Grain and fodder lay about among empty carts; all was in confusion, suggesting hasty departure.
“They have abandoned the camp,” said Meng You. “But this is only a ruse.”
Said Meng Huo, “I think that Zhuge Liang has important news from the capital that has made him leave without his baggage train like this. Either Wu has invaded or Wei has attacked. They left these lamps burning to make us think the camps were occupied, but they ran away leaving everything behind. If we pursue we cannot go wrong.”
So the King urged his army onward, himself heading the leading division. When they reached the Western River bank, they saw on the farther side that the camps were all in order and the banners flying as usual like a brightly tinted cloud of silk. Along the bank stood a wall of cloth. They dared not attack.
Meng Huo said to his brother, “This means that Zhuge Liang fears lest we may pursue. That is only a temporary halt, and they will retire in a couple of days.”
The Mangs camped on the river bank while they sent into the mountains to cut bamboos to make rafts. The boldest of the soldiers were placed in front of the camp till the rafts should be ready to cross. Little did Meng Huo suspect that the army of Shu was already within his borders.
