Zhang Yu and Cao ang came back from victory. They never thought, "Lord, after Cao's camp, there are several cities behind. I'm afraid it's not so easy for us to attack." Said Tess.
Zhang Yu looked at the map and pondered for a while, then said: "but after Cao Ying, we can threaten Cao Jun from north to south. That's why Cao ang chose to set up a camp dozens of miles ahead of here."
Cao ang built the camp here for the obvious purpose of limiting Zhang Yu to a certain extent and ensuring the safety of their rear area.
After the camp of the Cao army, there were several cities, and there were many places leading to the north and south.
Cao ang had their reasons for setting up the camp there, which could make Cao's rear safe all at once.
At this time, Cao ang had planned to retreat. If he didn't retreat, he just needed to strengthen his defense and send more troops from other places to defend Zhang Yu.
However, after their evaluation, Cao ang and Zhang Yu felt that they might fall into mutual consumption, so they decided to give up the camp and withdraw.
When Cao ang retreats, Zhang Yu naturally can't come to the door to provoke any more.
But Zhang Yu immediately changed a way.
Zhang Yu's army is on the border of Qingzhou and Jizhou.
In the north, Huang Zhong made rapid progress and had captured half of Bohai Prefecture, mainly because Yuan's army was unable to resist and had been retreating.
In the south, Zhang Yu has a lot of places to attack on the border between Qingzhou and Jizhou. The border between them is too long.
"Order the army to break up the whole into parts and harass everywhere, but not to lose too much." Zhang Yu ordered.
Qingzhou and Jizhou have hundreds of miles of border, where is the place to attack.
Zhang Yu plans to break the whole into parts and attack from several places.
Zhang Yu's purpose is to hold down Cao's army in more places. Cao's army should attack Jizhou cautiously.
Tens of thousands of troops scattered, all led by young generals.
Zhang Yu and Tai Shici are hiding in a place with 20000 troops to take care of these troops at any time.
More than a dozen soldiers and horses scattered, and they could attack a very large area. Some of them were along the border of Jizhou, some along the border of Qingzhou, and began to go far away.
Cao ang has been paying attention to Zhang Yu, waiting for Zhang Yu to attack. As a result, Zhang Yu's army suddenly disappeared.
Cao ang did not dare to be careless, and immediately arranged for someone to investigate.
A day later, Cao ang found out the details.
"Zhang Yu actually divided his troops, and they were so scattered that he wanted to attack everywhere." Cao ang said to Xun you and Jia Xu.
"Young master, Zhang Yu's move seems risky. In fact, it is not. His purpose is to hold down our army, not to fight with us. His subordinates judge that Zhang Yu will not let their army fight with us, but to harass us."
"Moreover, we can't ignore it. If we ignore it, Zhang Yu will become a real attack, and once they seize the opportunity, they will also attack us."
At present, Cao ang is facing a huge problem, how to deal with Zhang Yu's attack.
At first, Cao ang ordered all places to be on guard, because he was really unable to start.
Zhang Yu's troops are divided into more than a dozen. If you want to intercept them, you don't know where to intercept them. You can only let the army and the city guard carefully.
For two days, Zhang Yu's army did not launch any attack.
They are far away, but not in a hurry to attack.
The sudden appearance of the army made Cao Jun very uncomfortable.
The long border, Cao Jun suddenly stopped activities, transportation of food and grass dare not transport, hide inside the city.
The garrison quickly stepped up its defense, and many cities on the border were temporarily closed.
Zhang Yu's army roared past, then immersed again.
The whole border line became active, and Zhang Yu's army moved around the long border line.
Too active, the city is there, and Zhang Yu's soldiers turned around outside the city.
Some go straight through the city to the rear.
When Cao Jun sent someone to check, they ambushed dozens of scouts and then left.
Cao's generals were stunned. Five thousand troops came out to ambush dozens of their scouts.
But Zhang Yu's army did.
Zhang Yu's troops are crossing the border. Sometimes a city passes three armies in one day.
"To prepare ten days of dry food, we are ready to ambush a wave." Han Dong had been living on the border for five days when he suddenly smelled the opportunity.
Han Dong felt confused with his own army, not to mention the enemy.
So he thought and smelled the opportunity.
When there is a chance, Han Dong orders to prepare decisively.
Han Dong is a young general that Zhang Yu focuses on training. He has outstanding performance in Fusang. In this war, Han Dong still has a chance to play.
There are more than 130 young generals trained by Zhang Yu, but more than 50 of them have died in the war. The rest of them will continue to experience, and those who can finally grow up are the pillars of the army.
In the future, Zhang Yu will choose some people to focus on training every year. Undoubtedly, they are all highly educated people, many of whom graduated from colleges and universities.
Han Dong led 5000 troops. After wandering for a few days, he judged that the enemy must have been confused by them.
Han Dong went back to Qingzhou to replenish supplies, and then came out again as usual.
In the evening, they slip into the path, then make a detour in the woods, hiding their tracks.
The sudden loss of more than a dozen troops on the border did not arouse the idea of others. Even our own army did not know that they were hiding.
There is a lot of intelligence on the border. The enemy can receive more than ten different intelligence in one hour, and these intelligence seriously interfere with their judgment.
They collect so much information that they can't analyze the enemy's purpose at all. Often, they report the presence of a troop in the west a few minutes ago, and then report the presence of a troop in the East a few minutes later.
Even the number and number of the enemy were not clear, and the enemy disappeared again.
The city on the border is restless, and Zhang Yu's army will move within dozens of miles of the border.
Several times after Cao's troops were sent out, they disappeared immediately.
Cao Jun also knows that sooner or later something big will happen, but there is no good way at present.
Send a large army to encircle and suppress, then Zhang Yu's goal will be achieved, and Jizhou will not be easy to fight.
At this time, Cao Jun felt that Zhang Yu was too rogue.
