Xiahou Ba said, “Deng Ai is young, but he is deep and crafty. He has certainly taken great pains to secure the regions under his charge as General Who Pacifies the West. Victory will not be so easy as it was before.”
“Why should I fear him?” cried Jiang Wei, angrily. “You should not laud the spirit of the enemy and belittle that of our own soldiers. But in any case I have made up my mind and shall take Longxi.”
No one dared to offer any further opposition. Jiang Wei himself led the first army; the others followed in due order, and thus the soldiers of Shu marched out of Zhongti to Qishan.
Before they could reach Qishan, the scouts reported the hills already occupied by the armies of Wei. Jiang Wei rode forward to verify this, and, surely enough, he saw the Wei camps, nine in number, stretching over the hills like a huge serpent, and all arranged to give each other support.
“Xiahou Ba spoke only too well,” said he. “The plan of those camps is excellent and only our Zhuge Liang could have laid them out with equal skill.”
Returning to his own army, he said to his officers, “They must have known of my coming, and I think Deng Ai is here too. Now from this as base you are to send out daily small reconnoitering parties showing my banner, but different flags and uniforms, blue, yellow, red, white, and black, in turns. While you are thus distracting attention, I will lead the main army by Dongting to attack Nanan.”
Bao Su was sent to camp at the mouth of the Qishan Mountain Valley while the main army marched.
As soon as Deng Ai had heard that the enemy would come out at Qishan, he had camped there with his colleague Chen Tai. But when days had passed without anyone coming to fling a challenge, he sent out spies to find out where the Shu army was lurking. They could find nothing, and so Deng Ai went to the summit of a hill to look around.
He came to the conclusion, saying, “Jiang Wei must not be in this camp. He must be on his way to capture Nanan. Those soldiers in the Shu camp were nothing but a feint, accentuated by the daily change of uniform. Going to and fro for days, the horses look tired, and their leaders are certainly none of the ablest. Therefore, General, I advise an attack here. If that succeeds, the Dongting road can be occupied, and Jiang Wei will be unable to retreat. I think I ought to try to relieve Nanan. I will go by the Wucheng Mountain, and if I occupy that, the enemy will try to take Shanggui. Near that place is a narrow and precipitous valley called Block Valley, just the place for an ambush, where I shall lie in wait till Jiang Wei comes to take the Wucheng Mountain.”
Chen Tai replied, “I have been here over twenty years and have never known so much of the military possibilities of the place. You are very wonderful and must carry out your plan.”
So Deng Ai marched toward Nanan by double marches. Soon they came to the Wucheng Mountain, where they camped without opposition. He sent his son Deng Zhong and Shi Zuan, each leading five thousand troops, to lie in wait in the Block Valley and not to betray their presence.
In the meantime Jiang Wei was marching between Dongting and Nanan.
Near the Wucheng Mountain, he turned to Xiahou Ba and said, “That hill is our point, and Nanan is close. I fear lest the artful Deng Ai may seize and fortify it.”
They hastened, anxious to reach the hill before the enemy. But it was not to be. Presently they heard the roar of bombs and the beating of drums, and then flags and banners appeared, all of Wei. And among them fluttered the leader's standard, bearing the name “Deng Ai.”
This was a sad disappointment. The army of Shu halted, and veteran soldiers of Wei came rushing down from various points on the hill, too many for the troops of Shu to drive back. So the advance guard was defeated. Jiang Wei went to their help with his central body, but when he got near, the soldiers of Wei had retreated up to the hill.
Jiang Wei went on to the foot of the hill and challenged, but no one came out to accept. The soldiers of Shu began to shout abuse, and kept it up till late in the day, but they failed to provoke a fight. As the army of Shu began to retire, the Wei drums beat furiously, yet no one appeared. Jiang Wei turned about to ascend the hill, but its defenders prevented that by stones thrown from above. He hung on till the third watch, when he tried again. But he failed. Thereupon he went down the hill and halted, bidding his soldiers build a barricade of wood and boulders. The troops of Wei came on again, and the Shu troops scrambled to run to the old camp.
Next day Jiang Wei brought up many transport wagons and placed them on the slope as the nucleus of a camp. But in the night a number of Wei troops came down with torches and set fire to them. A fight ensued, which lasted till dawn.
Seeing that a camp could not be made there, Jiang Wei retired to consider new plans with Xiahou Ba.
