Zou Jing's questioning, from the perspective of the soldiers, is indeed old and serious, and it is very necessary to think clearly.

The water is soothing, even if it goes downstream, the speed of the boat is slower than that of a galloping horse, and it is even more difficult to catch up with the current.

However, since Li Su dared to make this suggestion, of course he had thought about it, and he asked someone to bring the wooden map at the moment.

Liu Bei next to him was already inspired, and he replied first: "Captain Zou, you and I have been fighting here for several months, and the terrain is already well understood.

The three tributaries of the water do not finally merge until they reach the territory of Yongnu County, Yuyang County. Therefore, even if the enemy had to cross the river in a roundabout way, he would never dare to make a detour back to the middle and upper reaches of the three tributaries, which had not yet converged. Otherwise, wouldn't you be caught in the urn of our army?

If Zhang Ju had just crossed the first tributary of Liangxiang County, but our army had rushed to the second and third tributaries of Changping and Yuyang to set up defenses, wouldn't he have been besieged in the Three Forks River and could not retreat? ”

After listening to this, Zou Jing also reacted quickly.

As mentioned earlier, they fought with Zhang Chun before, and the defensive core was also these three tributaries in the upper reaches of the river, Liu Bei, Jiao Touch, and Zhang Nan each guarded one, and the terrain was already too familiar to be familiar.

And where are the three tributaries of the Haihe River mentioned in Liu Bei's words and the Yongnu County where they eventually converge? It is about Wuqing County in Jinmen City.

And because during the Han Dynasty, the Yellow River had not washed the land on the Bohai Coast bigger and bigger, so the main urban area of Jinmen in later generations is now roughly the coastline. In the later generations, the Dagukou and Binhai New Area of Jinmen are still the sea.

Therefore, to prevent Zhang Ju from crossing the river and escaping back after the robbery, it is enough to hold the river equivalent to the short 20 kilometers from Wuqing County to the main urban area of Jinmen in the later generations.

"Yes, too...... Zhang Ju was the Taishou of Mount Tai, and he should be regarded as a person who knew a little about the soldiers, and he would not let himself fall into danger, if he only wanted to guard the forty miles of the river downstream, he could ignore more than a hundred miles upstream, and the grasp was much greater. ”

After Zou Jing figured it out, he nodded frequently.

On the Hebei Plain, there are few rivers that are large enough to hold back the army. As the boundary river between Youzhou and Jizhou, Xuanshui is already a relatively easy river to defend north of the Yellow River.

No fight here, no fight!

Seeing that Zou Jing and Liu Bei had unified their opinions, Liu Yu hurriedly asked: "Captain Zou, in this way, is it to mobilize most of the officers and troops in this state and move east to the area of the mouth of the sea?" ”

Zou Jing pondered for a few more breaths, and explained: "Envoy, that's roughly the case, but the rest of the risks can't be guarded against - first of all, although it is very important to intercept Zhang Ju, but Zhang Chun's Yanshan defense line cannot be relaxed, if it is too empty and Zhang Chun crosses Yanshan, it will not be optimistic."

Secondly, it is still necessary to deploy small groups of ranger reconnaissance patrols in the upper reaches of the river to ensure that when we cross the first tributary from the middle and upper reaches, we can detect the military situation in time, and then we will have enough time to rush to the third line of defense. Moreover, it is best to have a small group of mobile cavalry to harass and delay the enemy army on the way, so that the enemy will be able to retreat. ”

Liu Yu nodded after hearing this, feeling that it was indeed between the old and the serious.

You can't just ignore the midstream and upstream threats because they're small.

It's like you can't just defend the Sword Pavilion just because the probability of the enemy army entering Shu from the Yin Ping Road is extremely small, right?

So Liu Yu officially ordered: "In this case, according to what Captain Zou said, the deployment will start from now on!" It is impossible for Guanzicheng to rescue directly for the time being, so it can only cut off the grain and grass of the Wuhuan army under Guanzi City, and prevent them from plundering the grain and straw supplies in Jizhou, in order to change over time and the besieging enemy army will collapse before Gongsun Zhan. ”

After Liu Yu finished speaking, most people did not refute again, only Zhang Nan, the governor of Yuyang County, where the defense area was located in the easternmost part, was still a little uneasy and forcibly persuaded:

"Envoy! Even if this plan succeeds, our army temporarily trapped Zhang Ju in the lower reaches of the river and made it impossible to cross the river, but our army could not take the initiative to cross the river to pursue Zhang Ju and annihilate him.

In this way, as long as Zhang Ju is not in a hurry to cross the river and always flows in Bohai County, Jizhou, wouldn't we have to be deployed in the lower reaches of the river for a long time? After a long time, what if other defense areas show flaws?

Moreover, there are 100,000 Qiu Liju under Guanzi City, and they found that the partial division who went out to plunder the grain and grass has not returned for a long time, so what should be done when they come here to respond? At that time, wouldn't it be that our army on the east bank of Chen Bing's water would be flanked by Zhang Ju and Qiu Liju? ”

Zhang Nan asked this selfishly. Because his defense area is in the easternmost part of the three county defense areas, Yuyang County is now the enemy-occupied area of Youbeiping County, the enemy army in Youbeiping really reached the time when there was not enough food, and went west to meet the grain robbery troops, and the pressure behind it was borne by Zhang Nan.

And Liu Bei's defense area Zhuo County is in the westernmost part of the three counties, so he most hopes that the imperial court will concentrate the main force on the side of Zhang Ju to defend it, so that his pressure will be minimal.

Where there are people, there are rivers and lakes, even if they are all for the imperial court, and the officials want their jurisdictions to be as safe and complete as possible.

Therefore, listening to Zhang Nan's instigation, Liu Bei immediately jumped out: "How cowardly this is this!" Qiu Liju is known as a hundred thousand people, but in fact, most of them are farmers and coerced people, and they are still available to besiege Guanzi City, and if they want to run hundreds of miles to take the initiative to attack the field, they can't do it at all.

Moreover, not everyone in the Hu people has horses, Zhang Ju only sent thousands of partial divisions to plunder, so that one person could have two horses. And the main force of 100,000 camps, it would be good to have one or two thousand war horses. Even if the Xianbei people also joined forces with Qiu Liju, counting more than 10,000 horses from the Kebi Neng Department or the Suli Department, it was only 30,000 horses, and it was impossible for at least 70,000 or 80,000 people to come to Yuyang for reinforcements! All the departments of Zhuo County fully support the plan of the envoy and Captain Zou! ”

Zhang Nan grinned angrily, forced himself to go back, and reluctantly said that he had no objections.

A few months ago, when he fought against the Wuhuan Cliff King, Zhang Nan carried Liu Bei's injuries to harvest the spoils of war, and the two had a lot of grievances. Later, when he saw that Liu Bei had actually obtained as many as 2,000 horses from the King of Nanqiao, he was even more envious.

Now that he has done it again, the contradiction between the Zhuojun system and the Yuyang system has been completely made public.

The troops of each county immediately deployed according to the deployment of Liu Yu and Zou Jing.

Liu Yu glanced at Li Su, who was the first to propose "cutting off the enemy's partial division and returning home", and glanced at it slightly.

In addition, in order to temporarily requisition the fleet of the big businessman Mi family, Liu Yu also personally promised Mi Zhu a lot of benefits as compensation for delaying their business - this is the first time to come to Youzhou to sell horses on a large scale, Mi Zhu still attaches great importance to it, so he personally led the fleet. In the past two days, Liu Bei invited Mi Zhu to drink almost every meal, and the two seemed to be chatting very well. Now even Liu Yu has begun to show favor to Mi Zhu.

……

The war machine directly under the ship and the horse Xiaoxiao, and the Youzhou Mu Liu Yu was running rapidly, and in just two days, near the mouth of the lower reaches of the Bashui River, full preparations were made to intercept Zhang Ju's return journey.

At the same time, in the southern part of Bohai County, Zhang Ju, the new leader of the anti-thieves and the former Taishan Taishou, was not aware of any crisis at all.

This can't be blamed on him, because when he crossed the water and went south into Jizhou to plunder, Guan Yu and Li Su's fleet had not yet returned to Youzhou.

In this era, there was no precedent for anyone to drive a sea ship from Xuzhou to Youzhou to do sea trade.

The original boats on the Hao River were small fishing boats without roofs, and if they tried to carry soldiers to stop the Wuhuan cavalry, they would be wiped out by a rain of arrows from the archers, so who would be wary of such a threat that has never appeared?

"I've robbed enough for the time being, and I can't afford to rob my 7,000 people, and the cattle and donkeys that have been plundered from the people have also pulled carts and loaded goods, let's go."

It was June 26th, and seeing that tens of thousands of horses and thousands of cars were crammed to the brim, Zhang Ju was very satisfied.

In fact, if you really want to grab it, there are still a lot of things you can grab, but you really can't take it, so you should transport it back first and grab it next time.

This trip, in a sense, can be regarded as a return to his hometown - because he killed through the entire Bohai County, and also killed Pingyuan County, all the way to the border areas with Le'an County in Qingzhou and Taishan County in Yanzhou.

And his original official position was the Taishan County Guard of the Han Dynasty, which is tantamount to betraying the imperial court and actually returning to the jurisdiction when he was an official again, what a beautiful scenery!

The whole Jizhou, like a piece of paper, is unarmed! Let him come and go! Assassin Shi Jia Cong was actually paralyzed to such an extent!

After a day of slow swallowing, he saw that the boundary river of Youzhou and Jizhou was in front of him, and after crossing this river, he could return to Youzhou again.

A general under Zhang Ju's command also took the initiative to ask for instructions when the troops were approaching the water: "Your Majesty, the downstream of the water is deep, and it is not easy to wade in vain, why don't you swim through it like when you came?" It also saves the need to requisition ships. ”

Ladies and gentlemen, don't think it's strange that Zhang Ju's generals call him "Your Majesty", because Zhang Ju is a very arrogant person.

In history, he rebelled for only a few months, and he officially proclaimed himself the Son of Heaven, let Zhang Chun be called the general, and clearly raised the banner to replace the Han family.

In this life, although he has not yet proclaimed himself emperor externally, he has already asked his subordinates to call him Your Majesty.

Faced with the questions of his subordinates, Zhang Ju laughed directly: "Stupid! When I came, I traveled lightly and simply, not afraid to cross the river a few more times, of course, I had to walk in the shallow water. Now that you have brought so many heavy wagons, do you still let the chariots cross the river three times? It's better to find some boats and finish the battle. ”

"Your Majesty is wise, I can't wait!" The subordinate generals hurriedly received the order, and led hundreds of cavalry pioneers to speed up, and first went to the river to search for civilian boats.

It's a pity that the sycophant general didn't find the boat back.

About half an hour later, several rebel cavalry with arrows on their bodies staggered back: "Your Majesty...... Your Majesty! Captain Chen was killed by the Han army's random arrows, and dozens of big boats came to patrol back and forth on the water, and the civilian boats were also taken away by the Han army! I'll wait for my life to escape before I come back! ”

"What? How dare you kill the vanguard I sent to conquer ships? When Zhang Ju heard this, he was immediately furious.
