not return to give aid； the place of refuge is lost。 If he helps； then Yuan Tan will follow up and smite him； making use of your power to destroy the remnant of his brother's army； just as the autumn gale sweeps away the fallen leaves。 Now Liu Biao's Jingzhou is rich； the government peaceful； the people submissive； and it cannot be shaken。 Moreover； there is no greater threat to it than the North of Yellow River。 If that be reduced； then the task is plete。 I pray you； Sir； think of it。〃
〃I am sorry that I did not meet you earlier；〃 said Cao Cao； much gratified with this speech。
Forthwith orders were given to return and attack Jizhou。 Liu Bei； fearing this retirement was only a ruse； allowed it to proceed without interference and himself returned to Jingzhou。
When Yuan Shang heard that Cao Cao had crossed the Yellow River； he hastily led his army back to Yejun； ordering Lu Xiang and Lu Kuang to guard the rear。
Yuan Tan started from Pingyuan with a force in pursuit。 He had proceeded only a dozen miles when he heard a bomb and two bodies of troops came out in front of him and checked his progress。 Their leaders were Lu Xiang and Lu Kuang。
Yuan Tan reined in and addressed them； saying； 〃While my father lived； I never treated you badly。 Why do you support my brother and try to injure me？〃
The two generals had no reply to make； but they dismounted and bowed before him yielding submission。
Yuan Tan said； 〃Do not surrender to me but to the Prime Minister。〃
And he led them back to camp； where he waited the arrival of Cao Cao and then presented the pair。 Cao Cao received them well。 He promised his daughter to Yuan Tan to wife； and he appointed the two brothers as advisers。
When Yuan Tan asked Cao Cao to attack Jizhou； the reply was： 〃Supplies are short and difficult to transport。 I must turn the waters of River Ji into the White River whereby to convey my grain and afterwards I can advance。〃
Ordering Yuan Tan to remain in Pingyuan； Cao Cao retired into camp at Liyang。 The two brothers Lu Xiang and Lu Kuang； who were renegades from Yuan Shang； were now raised to noble rank and followed the army as supernumeraries。
Guo Tu noted this advancement and said to Yuan Tan； 〃He has promised you a daughter to wife。 I fear that bodes no good。 Now he has given titles of nobility to the two Lus and taken them with him。 This is a bait for the northern people； and at the same time he intends evil toward us。 You； my lord； should have two generals' seals engraved and send them secretly to the brothers so that you may have friends at court ready for the day when Cao Cao shall have broken your brother's power； and we can begin to work against him。〃
The seals were engraved and sent。
As soon as the Lu brothers received them； they informed Cao Cao； who smiled； saying； 〃He wants your support so he sends you seals as officers。 I will consider it as soon as Yuan Shang has been dealt with。 In the meantime you may accept the seals till I shall decide what to do。〃
Thenceforward Cao Cao planned Yuan Tan's doom。
Shen Pei and his master also discussed the current situation。 Yuan Shang said； 〃Cao Cao is getting grain into the White River； which means an attack on Jizhou。 What is to be done？〃
Shen Pei replied； 〃Send letters to Yin Kai； mander of Wuan； bidding him camp at Maocheng to secure the road to Shangdang； and direct Ju Gu； son of Ju Shou； to maintain Handan as a distant auxiliary。 Then you may advance on Pingyuan and attack Cao Cao。〃
The plan seemed good。 Yuan Shang left Shen Pei and Chen Lin in charge of Yejun； appointed two manders Ma Yan and Zhang Zi as Van Leaders； and set out hastily for Pingyuan。
When Yuan Tan heard of the approach of his brother's army； he sent urgent messages to Cao Cao； who said to himself； 〃I am going to get Jizhou this time。〃
Just at this time it happened that Xun You came down from the capital。 When he heard that Yuan Shang was attacking his brother Yuan Tan； he sought Cao Cao and said； 〃You； Sir； sit here on guard。 Are you waiting till Heaven's thunder shall strike the two Yuans？〃
〃I have thought it all out；〃 said Cao Cao。
Then he ordered Cao Hong to go and fight against Yejun； while he led another army against Yin Kai in Maocheng。 Yin Kai could make no adequate defense and was killed by Xu Chu。 His soldiers ran away and presently joined Cao Cao's army。 Next Cao Cao led the army to Handan； and Ju Gu came out to fight him。 Zhang Liao advanced to fight with Ju Gu； and after the third encounter Ju Gu was defeated and fled。 Zhang Liao went after him； and when their two horses were not far apart； Zhang Liao took his bow and shot。 The fleeing warrior fell as the bowstring twanged。 Cao Cao pleted the rout； and Ju Gu's force was broken up。
Now Cao Cao led his armies to an attack on Yejun。 Cao Hong had arrived before； and a regular siege began。 The army enpassed the city and began by throwing up great mounds。 They also tunneled subterranean ways。
Within the city Shen Pei turned his whole care to the defense and issued the severest mands。 The mander of the East Gate； Feng Li； got intoxicated and failed to keep his watch for which he was severely punished。 Feng Li resented this； sneaked out of the city； went over to the besiegers； and told them how the place could be attacked。
〃The earth within the Pearly Gate is solid enough to be tunneled； and entrance can be effected there；〃 said the traitor。
So Feng Li was sent with three hundred men to carry out his plan under cover of darkness。
After Feng Li had deserted to the enemy； Shen Pei went every night to the wall to inspect the soldiers on duty。 The night of the sapping he went there as usual and saw that there were no lights outside the city and all was perfectly quiet。
So he said to himself； 〃Feng Li is certain to try to e into the city by an underground road。〃
Whereupon he ordered his troops to bring up stones and pile them on the cover of the tunnel opening。 The opening was stopped up and the attacking party perished in the tunnel they had excavated。
Cao Cao having failed in this attempt abandoned the scheme of underground attack。 He drew off the army to a place above the River Huan to await till Yuan Shang should return to relieve the city。
Yuan Shang heard of the defeat of Yin Kai and Ju Gu； and the siege of his own city； and bethought himself of relieving it。
One of his manders； Ma Yan； said； 〃The high road will surely be ambushed。 We must find some other way。 We can take a by…road from the West Hills and get through by River Fu； whence we can fall upon Cao Cao's camp。〃
The plan was acceptable and Yuan Shang started off with the main body； Ma Yan and Zhang Zi being rear guard。
Cao Cao's spies soon found out this move； and when they reported it； he said； 〃If Yuan Shang es by the high road； I shall have to keep out of the way； but if by the West Hills' by…road； I can settle him in one battle。 And I think he will show a blaze as a signal to the besieged that they may make a sortie。 I shall prepare to attack both。〃
So Cao Cao made his preparations。 Now Yuan Shang went out by River Fu east toward Yangping； and near this he camped。 Thence to Yejun was five miles。 River Fu ran beside the camp。 He ordered his soldiers to collect firewood and grass ready for the blaze
