ers from left and right。 Wei Yan and Ma Dai fought desperately to extricate themselves； but many of the soldiers of Shu fell into the river and drowned。 The others scattered。 However； Wu Yi came up and rescued the force from entire destruction； and moved across the river to make camp。
Hu Ban set half his troops to navigate the rafts down the river to the bridges。 But Zhang Hu and Yue Chen stationed near the bridges shot clouds of arrows at them； and the Shu leader； Hu Ban； was wounded。 He fell into the river and was drowned。 The crews of the rafts jumped into the water and got away。 The rafts fell into the hands of the soldiers of Wei。
At this time the front division under Wang Ping and Zhang Ni were ignorant of the defeat of their Beiyuan army； and they went straight for the camps of Wei。 They arrived in the second watch。
They heard loud shouting； and Wang Ping said to Zhang Ni； 〃We do not know whether the cavalry sent to Beiyuan has been successful or not。 It is strange that we do not see a single soldier of the enemy。 Surely Sima Yi has found out the plan and prepared to frustrate the attack。 Let us wait here till the bridges have been set on fire and we see the flames。〃
So they halted。 Soon after； a mounted messenger came up with orders： 〃The Prime Minister bade you retire immediately； as the attack on the bridges has failed。〃
Wang Ping and Zhang Ni attempted to withdraw； but a bomb exploded and the troops of Wei； who had taken a by…road to their rear； at once attacked。 A great fire started also。 A disorderly battle ensued； from which Wang Ping and Zhang Ni eventually forced their ways out； but only with great loss。
And when Zhuge Liang collected his army at Qishan once more he found； to his sorrow； that he had lost more than ten thousand troops。
Just at this time Fei Yi arrived front Chengdu。
Zhuge Liang received him and； after the ceremonies were over； said； 〃I would trouble you； Sir； to carry a letter for me into East Wu。 Will you undertake the mission？〃
〃Could I possibly decline any task you laid upon me？〃 said Fei Yi。
So Zhuge Liang wrote a letter and sent it to Sun Quan。 Fei Yi took it and hastened to Capital Jianye； where he saw Sun Quan； the Ruler of Wu； and presented this letter：
〃The Hans have been unfortunate； and the line of rulers has been broken。 The Cao party have usurped the seat of government and still hold the mand。 My late master； Emperor Bei； confided a great task to me； and I must exhaust every effort to achieve it。 Now my army is at Qishan； and the rebels are on the verge of destruction on River Wei。 I hope Your Majesty； in accordance with your oath of alliance； will send a leader against the north to assist by taking the Middle Land； and the empire can be shared。 The full circumstances cannot be told； but I hope you will understand and act。〃
Sun Quan was pleased at the news and said to the envoy； 〃I have long desired to set my arm in motion； but have not been able to arrange with Zhuge Liang。 After this letter I will lead an expedition myself； and go to Juchao and capture Xincheng of Wei。 Moreover； I will send Lu Xun and Zhuge Jin to camp at Miankou and Jiangxia； and take Xiangyang。 I will also send another army under Sun Shao and Zhang Cheng into Guangling to capture Huaiyang。 The total number will be three hundred thousand troops； and they shall start at once。〃
Fei Yi thanked him and said； 〃In such a case the Middle Land will fall forthwith。〃
A banquet was prepared。 At this； Sun Quan said； 〃Whom did the Prime Minister send to lead the battle？〃
Fei Yi replied； 〃Wei Yan was the chief leader。〃
〃A man brave enough； but crooked。 One day he will work a mischief unless Zhuge Liang is present。 But surely Zhuge Liang knows。〃
〃Your Majesty's words are to the point；〃 said the envoy。 〃I will return at once and lay them before Zhuge Liang。〃
Fei Yi quickly took leave and hastened to Qishan with his news of the intended expedition of Wu against Wei with three hundred thousand troops in three directions。
〃Did the Ruler of Wu say nothing else？〃 asked Zhuge Liang。
Then Fei Yi told him what had been said about Wei Yan。
〃Truly a prehending ruler；〃 said Zhuge Liang； appreciatively。 〃But I could not be ignorant of this。 However； I value Wei Yan because he is very bold。〃
〃Then Sir； you ought to decide soon what to do with him。〃
〃I have a scheme of my own。〃
Fei Yi returned to Chengdu； and Zhuge Liang resumed the ordinary camp duties of a leader。
When Zhuge Liang was in a council with his manders； suddenly a certain Wei leader came and begged to be allowed to surrender。 Zhuge Liang had the man brought in and questioned him。
〃I am a leader； Zheng Wen by name。 General Qin Lang and I are old colleagues。 Recently Sima Yi transferred us and； showing great partiality for my colleague； appointed him Leader of the Van and threw me out like a weed。 I was disgusted and left； and I wish to join your ranks if you will accept my service。〃
Just at that moment a soldier came in to say that Qin Lang with a pany had appeared in front of the tents and was challenging Zheng Wen。
Said Zhuge Liang； 〃How does this man stand with you in fighting skill？〃
〃I should just kill him；〃 said Zheng Wen。
〃If you were to slay him； that would remove my doubts。〃
Zheng Wen accepted the proposer with alacrity； mounted his horse； and away he went。 Zhuge Liang went out to see the fight。 There was the challenger shaking his spear and reviling his late friend as rebel and brigand and horse…thief。
〃Traitor！ Give me back my horse you stole！〃 cried Qin Lang； galloping toward Zheng Wen as soon as he appeared。
Zheng Wen whipped up his horse； waved his sword； and went to meet the attack。 In the first bout he cut down Qin Lang。 The Wei soldiers then ran away。 The victor hacked off the head of his victim and returned to lay it at Zhuge Liang's feet。
Seated in his tent； Zhuge Liang summoned Zheng Wen and burst out： 〃Take him away and behead him！〃
〃I have done nothing wrong！〃 cried Zheng Wen。
〃As if I do not know Qin Lang！ The man you have just killed was not Qin Lang。 How dare？ you try to deceive me？〃
Zheng Wen said； 〃I will own up。 But this was his brother Qin Ming。〃
Zhuge Liang smiled。
〃Sima Yi sent you to try this on for some reason of his own； but he could not throw dust in my eyes。 If you do not tell the truth； I will put you to death。〃
Thus caught； the false deserter confessed and begged his life。
Zhuge Liang said； 〃You can save your life by writing a letter to Sima Yi telling him to e to raid our camp。 I will spare you on this condition。 And if I capture Sima Yi； I will give you all the credit and reward you handsomely。〃
There was nothing for it but to agree； and the letter was written。 Then Zheng Wen was placed in confinement。
But Fan Jian asked； 〃How did you know this was only a pretended desertion？〃
〃Sima Yi looks to his people；〃 replied Zhuge Liang。 〃If he made Qin Lang a leading general； Qin Lang was certainly a man of great military skill and not the sort of man to be overe by this fellow Zheng Wen in the first encounter。 So Zheng Wen's opponent certainly was not Qin Lang。 That is how I knew。〃
They congratulated him on his perspicacity。 Then Zhuge Liang selected a certain persuasive speaker from among his officers and whispered certain instructions in his ear。 The officer at once left and carried the letter just written to the Wei camp； where he asked to see the mander…in…Chief。 He was admitted； and the letter was read。
〃Who are you？〃 said Sima Yi。
〃I am a man from the Middle Land； a poor fellow stranded in Shu。 Zheng Wen and I are fellow villagers。 Zhuge Liang has given Zheng Wen a Van Leadership as a reward for what he has done； and Zheng Wen got me to bring this letter to you and to say that he will show a light tomorrow evening as a signal； and he hopes you will lead the attack yourself。 Zheng Wen will work from the inside in your favor。〃
Sima Yi took great pains to test the reliability of these statements； and he examined the letter minutely to see if it bore any signs of fabrication； but he found it was Zheng Wen's writing。
Presently he ordered in refreshments for the bearer of the letter； and then he said； 〃We will fix today at the second watch for the raid； and I will lead in person。 If it succeeds； I will give you a good appointment as a reward。〃
Taking leave； the soldier retraced his steps to his own camp and reported the whole interview to Zhuge Liang。
Zhuge Liang held his sword aloft toward the North Star； took the proper paces for an incantation； and prayed。
This done； he summoned Wang Ping； Zhang Ni； Wei Yan； Ma Dai； Ma Zheng； and Jiang Wei； to whom he gave certain instructions。 When they had gone to carry them out； he ascended a hill； taking with him a few score guards only。
Sima Yi had been taken in by Zheng Wen's letter and intended to lead the night raid。 But the elder of his sons； Sima Shi； expostulated with his father。
〃Father； you are going on a dangerous expedition on the faith of a mere scrap of paper；〃 said his son。 〃I think it imprudent。 What if something goes unexpectedly wrong？ Let some general go in your place； and you e up in rear as a reserve。〃
Sima Yi saw there was reason in this proposal； and he finally decided to send Qin Lang； with ten thousand troops； and Sima Yi himself would mand the reserve。
The night was fine with a bright moon。 But about the middle of the second watch the sky clouded over； and it became very black； so that a man could not see his next neighbor。
〃This is providential；〃 chuckled Sima Yi。
The expedition duly started； soldiers with gags； and horses with cords round their muzzles。 They moved swiftly and silently； and Qin Lang made straight for the camp of Shu。
But when he reached it and entered； and saw not a soldier； he knew he had been tricked。 He yelled to his troops to retire； but lights sprang up all round； and attacks began from four sides。 Fight as he would； Qin Lang could not free himself。
From behind the battle area Sima Yi saw flames rising from the camp of Shu and heard continuous shouting； but he knew not whether it meant victory for his own army or to his enemy。 He pressed forward toward the fire。 Suddenly； a shout； a roll of drums； and a blare of trumpets close at hand； a bomb that seemed to rend the earth； and Wei Yan and Jiang Wei bore down upon Sima Yi； one on each flank。 This was the final blow to him。 Of every ten soldiers of Wei； eight or nine were killed or wounded； and the few others scattered to the four winds。
Meanwhile Qin Lang's ten thousand troops were falling under arrows that came in locust…flights； and their leader was killed。 Sima Yi and the remnant of his army ran away to their own camp。
After the third watch the sky cleared。 Zhuge Liang from the hill…top sounded the gong of retreat。 This obscurity in the third watch was due to an incantation called Concealing Method。 The sky became clear； because Zhuge Liang performed another incantation to have the Deities of Six Layers sweep away the few floating clouds that still persisted。
The victory was plete。 The first order on Zhuge Liang's return to camp was to put Zheng Wen to death。
Next he considered new plans for capturing the south bank。 Every day be sent a party to offer a challenge before the camps of the enemy； but no one accepted。
One day Zhuge Liang rode in his small chariot to th
