Yuan Shao summoned the lictors and sent away the adviser in chains, saying, “When I have overcome Cao Cao, then will I deal with you and Tian Feng together “
The huge army was camped in four divisions, one toward each point of the compass. The camps were thirty miles in circuit. Scouts and spies were sent out to discover the strong and the weak points of the enemy.
Cao Cao's army arrived and were smitten with fear when they heard of the strength of their enemy. The leader called together his council.
Then said Adviser Xun You, “The enemy are many but not terrible. Ours is an army of veterans, every soldier of ours worth ten of theirs; but our advantage lies in a speedy battle, for unhappily our stores are insufficient for a long campaign.”
“You speak to the point,” said Cao Cao. “I think the same.”
Therefore Cao Cao issued orders to press noisily forward and force on a battle. Yuan Shao's soldiers took up the challenge, and the two sides were arrayed. On Yuan Shao's side, Shen Pei placed ten thousand of crossbowmen in ambush on the two wings, while five thousand of archers held the center. The signal for general attack was a bomb, and the onset was to continue through three rolls of the drum.
Yuan Shao wore a silver helmet and breastplate and an embroidered robe held in by a jeweled belt. He took up his post in the center with his commanders — Gao Lan, Zhang He, Han Meng, Chunyu Qiong, and others — ranged right and left. His banners and ensigns made a brave show.
When Cao Cao's army's center opened and the banners moved aside, the chieftain appeared on horseback with his staff of doughty leaders all fully armed — Xu Chu, Zhang Liao, Xu Huang, Li Dian, and others.
Pointing with his whip at Yuan Shao, Cao Cao cried, “In the presence of the Emperor, I pressed your claims to consideration and obtained for you the title of Regent Marshal; why do you now plan rebellion?”
Yuan Shao replied, “You take the title of a minister of Han, but you are really a rebel against the House. Your crimes and evil deeds reach to the heavens, and you are worse than the usurper Wang Mang and the rebel Dong Zhuo. What are these slanderous words about rebellion that dare you address to me?”
“I have a command to make you prisoner!”
“I have the Girdle Decree to arrest rebels!” replied Yuan Shao.
Then Cao Cao became wrathful and bade Zhang Liao ride forth as his champion. From the other side rode Zhang He on a curvetting steed. The two champions fought four or five bouts with no advantage to either. In his heart Cao Cao thought the contest amazing. Then Xu Chu whirled up his sword and went to help. From the other side, to match him rode out Gao Lan with his spear set, and the contestants were now four, battling two and two. Then Cao Cao ordered three thousand troops under Xiahou Dun and Cao Hong to attack the opponents' array. Thereupon on Yuan Shao's side, Shen Pei gave the signal for attack, and the legion of crossbowmen on the wings shot and the center archers let fly all together. The arrows flew all over the field in front, and Cao Cao's troops could not advance. They hastened away toward the south. Yuan Shao threw his soldiers on their rear, and they were broken. They fled away toward Guandu, and Yuan Shao advanced another stage. He camped near them.
Then Shen Pei said, “Now send one hundred thousand soldiers to guard Guandu, and get near Cao Cao's camp; then build up observation mounds to get a clear view of the enemy, and choose vantage points whence to shoot arrows into the midst of their host. If we can force him to evacuate this place, we shall have gained a strategic point whence Capital Xuchang can be attacked.”
Yuan Shao adopted this suggestion. From each of the camps, they sought out the strongest veterans who dug with iron spades and carried earth to raise mounds near Cao Cao's camp.
Cao Cao's soldiers saw what their enemies were doing and were anxious to make a sortie and drive them off. But the archers and crossbowmen came out commanding the narrow throat through which it was necessary to attack and stayed them. At the end of ten days, they had build up more than half a hundred mounds, and on the summit of each was a lofty tower, whence the archers could command their opponents' camp. Cao Cao's soldiers were greatly frightened and held up their bucklers to keep off the various missiles. From the mounds the arrows flew down like a fierce rain after each roll of drums. The soldiers of Yuan Shao's army laughed and jeered when they saw their enemies crouching under their shields and crawling on the ground to avoid their missiles.
Cao Cao saw that his troops were getting out of hand under this attack, so he called a council.
Liu Ye spoke up, saying, “Let us make catapults and so destroy them.”
Cao Cao at once had models brought and set cunning workers to make these stone-throwing machines. They soon constructed some hundreds and placed them along the walls of the camp inside, just opposite the high ladders on the enemy's mounds.
