that the building is about to be burned。〃
〃Ah ! If only Zhuge Liang the Martial Lord was still alive………how different all would be!〃 said Sun Xiu; with a sigh。
Letters were prepared saying that beyond doubt Sima Zhao intended usurpation; and when that came about in Wei; both Wu and Shu would be invaded。 Wherefore both should be ready。
On the arrival of these letters; Jiang Wei hastened to seek permission to attempt another expedition。 Consent being given; a large army marched into Hanzhong in the winter of the first year of Wonderful Sight (AD 258)。 Liao Hua and Zhang Yi were appointed Leaders of the Van; Wang Han and Jiang Bin as manders of the Left Army; and Jiang Shu and Fu Qian as manders of the Right Army; while Jiang Wei and Xiahou Ba led the main column。
Asked what he thought should be the first objective; Xiahou Ba replied; 〃There is no better fighting ground than Qishan; as the tactics of the late Prime Minister made evident; and it is the only good exit。〃
So thither three armies marched; and they made three camps at the entrance to the valley。 At this time Deng Ai had a training camp at Qishan drilling the Longyou troops。
The scouts told him: 〃The Shu army have pitched three camps in the valley。〃
He ascended a hill to see and verify their reports。 He seemed pleased when he saw the enemy camp。
〃They have just done as I foresaw;〃 said Deng Ai。
Now Deng Ai had carefully considered the topography of the countryside; and so had not interfered with the Shu army when it was on the march or settling into camp。 Moreover; he had excavated a subterranean road to the spot where he had thought they would halt; and their left camp had been pitched just on it。 Wang Han and Jiang Bin manded in that camp。
Deng Ai called his son Deng Zhong and Shi Zuan and sent them with ten thousand troops each to attack the left camp; one on each flank。 Then he sent Zheng Lun and five hundred troops into the underground road; which opened in rear of the camp of Wang Han and Jiang Bin。
As the newly made camp was not yet well fortified; Wang Han and Jiang Bin exercised great care and kept their troops under arms all night; watching with vigilance。 So when the alarm was given; they had but to seize their weapons and go out。 But as the two leaders were mounting their steeds; Deng Zhong and Shi Zuan had attacked from without; and Zheng Lun from within。 Thus attacked from three sides; soon Wang Han and Jiang Bin found the position untenable and fled。
When Jiang Wei saw that his left camp had been attacked on three sides; he mounted and took his position in front of the center camp。
〃Let no one move on pain of death!〃 he shouted。 〃Stand still。 When the enemy approaches; shoot!〃
The right camp was ordered to stand fast。 His defense was effective。 A dozen of times the troops of Wei came forward; only to be driven back before the arrows and bolts of the defenders。 Daylight found the Shu camps still firm; and the Wei troops drew off。
〃Jiang Wei has indeed learned of Zhuge Liang;〃 said Deng Ai。 〃His soldiers stood the night attack without flinching; and the leaders took the chances of battle quite calmly。 He is able。〃
Next day; when Wang Han and Jiang Bin went to confess their fault; Jiang Wei said; 〃It was less your fault than mine; for I did not clearly recognize the nature of the terrain。〃
So no penalty was inflicted。 The camp was made stronger; and the subterranean passage was filled with the bodies of the slain。
A challenge to battle for the following day was sent to Deng Ai; who accepted it joyfully。
Next day the two armies were arrayed in front of the Qishan Mountains。 The troops of Shu arrayed according to the 〃Eight Formations〃 designed by Zhuge Liang; which are called Heaven; Earth; Wind; Cloud; Bird; Serpent; Dragon; and Tiger。 While the maneuver was in progress; Deng Ai recognized it as the Eight Gates Formation and placed his troops accordingly。
Jiang Wei then gripped his spear and rode out; saying; 〃You have made a good imitation of my eight; but can you work variations?〃
〃You call these yours! Did you think that you alone held the secret? Since I have made it; of course I know the variations。〃
Deng Ai reentered his ranks; gave the signal officers certain orders; and the eight gates were evolved in rapid succession into sixty…four gates。 Then he rode to the front again。
〃What of my evolution?〃 asked Deng Ai。
〃Not so bad。 Would you like to try a surrounding move with me?〃 replied Jiang Wei。
〃Why not?〃
The two armies moved in orderly ranks。 Deng Ai stood in the midst of his army giving the necessary orders。 Then the clash came; but his tactics did not grip。 Then Jiang Wei waved a certain signal flag; and his force suddenly assumed the form of a serpent coiled on the ground with Deng Ai in the center。 Shouts arose all about him; and Deng Ai could not understand what had happened and began to feel afraid。 Gradually the troops of Shu closed in upon him; and he saw no way of escape。
〃Deng Ai; you must surrender!〃 cried the soldiers。
〃Indeed a moment of pride had led me into the trap of Jiang Wei!〃 he sighed。
Suddenly from the northwest a cohort dashed in。 To Deng Ais great joy they were soldiers of Wei; and they forced over the battle array and released him。 The leader was Sima Wang。
But although Deng Ai had been rescued; his nine camps were seized by his enemy and he had to retire。 He led his army to the south of River Wei and made a camp。
〃How did you know exactly where to strike in that maze?〃 asked Deng Ai of his rescuer。
Sima Wang replied; 〃In my youth I went to study in Jingzhou and was friendly with Shi Guangyuan and Cui Zhouping。 They explained that formation to me。 Jiang Wei used what is known as The Serpent Coil; and the only way to break it is to attack the head; which I saw was in the northwest。〃
Deng Ai replied; 〃Although I have studied formations; I do not know all the modifications。 But since you know about this; we may be able to recover our camps。〃
〃I fear the little I have learned will not be enough to overe Jiang Wei。〃
