This response was not expected by Li Zicheng. Since the Tiger Guard entered the battlefield, there has been no hearing of the voluntary surrender of the guards. In fact, Li Zicheng also understands that there are not many conditions for him to persuade him to surrender, from Li Yan, he learned that Huwei's treatment is very good, and Yu Guozhen's career is also booming, almost everyone can see that his future is bright, and no one will betray him at all.

"If you don't die in the Yellow River, you're probably still counting on Yanzhou to help." Li Zicheng sneered, and then ordered: "Siege!" ”

On the Yanzhou side, the battle has lasted for seven days, and Gao Jie finally waited for the long-awaited Liu Liangzuo. The two sides joined forces, and the number of troops reached 120,000, and the number of tiger guards guarding Yanzhou, Gao Jie finally figured out, a total of only 10,000.

Moreover, there are 3,000 people who are guerrilla out, attacking his grain road, and the only people who are really guarding Yanzhou City are only 7,000 people.

This made Gao Jie give up all his previous hesitation.

"Today we will have a general attack, we can't delay any longer, our grain and grass are almost finished, capture Yanzhou, we will be able to have enough grain and grass, and then we will harvest half of your and my two armies." Gao Jie said to Liu Liangzuo.

"Brother Gao, just rest assured." Liu Liangzuo smiled gloomily: "However, Brother Gao has attacked Yanzhou City these days, how is the situation of the guards of the Yu thief?" ”

"The garrison is very tight, I attacked several times, suffered heavy losses, and could only retreat temporarily, but with Brother Liu's help, it is different, I am from the east and west, Brother Liu is from the south, we attack together, the defenders are only seven thousand, and I have also sent people to inquire about the Yu ** soldiers here. is not as brave as Qingdao Pass, so he can only do the work of an auxiliary soldier. ”

"That's according to Gobb's."

The two of them have discussed and decided, and as for Zu Kuan and Zhou Zhong's opinions, they are not in their consideration at all. Liu Liangzuo was responsible for attacking the city from the south, and when he supervised the commander's headquarters to the front of the city, he looked through a telescope and found that the forts on the city were dense. To say the least, there were also one or twenty pieces of artillery in the city. Not only that, but the city is also densely covered with ravines, one after another. At least six trenches have been dug for the defenders!

"For the past few days, as long as there is no fighting, the city will send out men to dig trenches, and the trenches will be chest-deep. It will cause some trouble for our siege, but as long as we are not afraid of casualties, it only takes half a day to fill in the trenches. "The man sent by Gao Jie next to him.

"Hmm." Liu Liangzuozai looked at it carefully for a while, and then smiled and said to the people around him: "Brother Liheng, what do you think?" ”

The "Brother Liheng" who followed Liu Liangzuo was dignified and extremely good-looking, but he looked a little like the legendary Guan Yu Guan Yunchang. He squinted his eyes for a moment, and then said, "These trenches are not for stopping us. If we want to stop our siege, we should widen it and lead water into the ditch. ”

"It's Brother Liheng, what else?" Liu Liangzuo asked again.

The staff member sent by Gao Jie was a little surprised, and he also knew Liu Liangzuo's character. It's not much better than Gao Jie, but for this "Brother Liheng", he looks down on him and respects him very much, but I don't know why.

"I see that he was still carrying sacks of earth and piling them out of the stacks—which must have been for people to stand in the ditch. Shoot at us right on the battlement. I understand that there is no danger in Yanzhou City, except for the city wall, it is difficult to have horns outside the city, so Yu Guozhen's subordinates dug these trenches and divided them to defend them, which is a law. ”

"Yu Guozhen's department mostly used muskets to shoot in the trenches...... This is equivalent to adding a few lines of defense for firing. Moreover, the trenches are horizontal and vertical, which is conducive to its movement in the trenches, and indeed, it has added trouble to our siege. Liu Liangzuo said: "However, you have to try the power of these trenches...... Brother Liheng swept the battle for me. ”

After finishing speaking, Liu Liangzuo gave orders to his subordinates, and after a while, the forward composed of death squads began to approach Yanzhou City.

As the "Brother Liheng" said, the purpose of the trench is indeed to shoot.

In Europe at this time, there were still neat phalanxes at the time of the battle, and the two sides approached each other, and then lined up to close their guns. Storm the enemy's flanks with cavalry and, of course, protect your musketeers with pikemen. In China, since Qi Jiguang's regular army was drifted away by bureaucrats at all levels of the Ming Dynasty, all tactics relied on loyal and brave soldiers, but Jianyu learned how to use tactics with the original Ming army in Liaodong, so that he felt Luo's infantry armor and Nala's iron cavalry. As for the trenches, they are generally used to protect the camp tent from direct impact when camping, and it is the first time that it has been used in specific operations.

In this era, only Huwei can use this tactic, because the musket equipped by Huwei is a rifled musket, both in terms of range and accuracy has made great progress, and in the fifteenth year of Chongzhen, the rear-loading gun that has plagued Yu Guozhen for a long time has finally been successfully developed, and now Huwei is already using a rear-loading rifled gun, which has greatly improved the speed and lethality of reloading.

Then there is the barbed wire, for Liu Liangzuo and others, barbed wire is not new, Yu Guozhen often uses a lot of barbed wire when isolating the victims, so when they see the barbed wire in front of the trench, they know that it is used to stop the cavalry charge.

The 200 death squads that launched the tentative attack all died in front of the barbed wire, and they could not even tear it open.

Liu Liangzuo suddenly jumped a few times at his temple, and said to the "Brother Liheng" with a wry smile: "It seems that there is no way to break through this city without paying heavy casualties, I don't know if the other two sides are the same." ”

"No wonder, no wonder...... Brother Mingfu, I still think that it is better not to fight if you can. The Northern Expedition to recover the Beijing Division, you have the name of righteousness in your hands, and if you want to come to Nanhaihou, you may not really be able to stop it. ”

"It's not that you haven't seen Yu Thief's Xinxiang Daily, where the imperial court is called the Jinling Small Imperial Court, and its intention of not being subordinate has been clearly revealed. Moreover, Yu Guozhen sat on a strong army, and when the thieves entered Beijing, not only did he not save them, but he supplied the thieves with grain and grass in Xuzhou, and after the fall of Beijing, he sold his reputation to buy people's hearts. If he can be loyal to the Ming Dynasty and is willing to lead the Northern Expedition, I, Liu Liangzuo, am willing to immediately disarm and give away all the tens of thousands of soldiers and horses in my hands! Liu Liangzuo sighed.

He said it sincerely, and the brother Liheng frowned slightly, as if he was moved.

"Brother Liheng is a native of Jingshi, Jingshi was first robbed, and then he was captured, and those who suffered were all Brother Liheng's fathers and fellow villagers. Brother Liheng should have relatives who are still in Beijing, so he doesn't want to know if they are safe now, so he doesn't want to go to the ancestral grave to worship? ”

Speaking of which, although he knew that Liu Liangzuo was provoking him, this Brother Liheng also had to be fooled.

He was originally a person with a fierce personality, and although he was resourceful, he had a passionate heart. With a long sigh, he said: "I originally had high hopes for the Marquis of Nanhai, hoping that he could sweep away the thieves and assist me in the Ming Dynasty." However, he did not move forward in the east of the mountain, but blocked the road of the imperial court's northern expedition, and I was really helpless to be an enemy of him—anyway, it was not difficult to break through this trench. ”

Liu Liangzuo listened to what he said before, and he was secretly happy in his heart, and then he said that it was not difficult to break the trench, and he was even more ecstatic: "I knew that Brother Liheng had a way, and it was not in vain that I invited Brother Liheng from Jiangyin!" ”

"Without it, one word, 'water' ear." Brother Liheng said.

As soon as these words came out, Liu Liangzuo immediately understood that he was also used to fighting, but he didn't think about it for a while.

The other party digs a trench and puts the soldiers on low ground, so diverting water to flood irrigation, isn't it a matter of pushing the boat down the river?

And on the bank of Yanzhou, Yishui, Surabaya, Baima River, the three rivers are surging out of the mountains, and now it is the season of abundant water, as long as the embankment is dug again, and the water is diverted to irrigate the city, not only can break the other party's trench array, but even the city wall is blistered!

"Come on, come on, go and ask Uncle Gao to come and discuss—no, I'll go myself!" Liu Liangzuo said with a smile.

The news that Nan Mian had just tested the firepower and did not continue the attack soon reached Wang Haoran's ears.

Looking through the distance with a telescope at the head of the city, Wang Haoran was a little surprised.

Sending soldiers to guerrilla warfare in the field, forcing the coalition forces to storm the city quickly, and unable to bypass Yanzhou to attack the more empty hinterland, was his tactic. As the commander-in-chief of Yanzhou, he has the right to make decisions on the spot, and this tactical arrangement has also been recognized by the vast majority of his colleagues.

It stands to reason that the coalition forces, which are short of food and grass, should immediately launch an attack on all fronts, attacking the positions he has arranged in waves. However, after the probing attacks in the west and south, the other side stopped moving, and the reason for this was that they were discussing ways to break the trench tactics.

Wang Haoran grinned, and there was some cunning in his eyes.

The trench tactic was proposed by Yu Guozhen when he gave a lesson on the future development of the war to the Huwei Staff Corps, but this tactic was first used by Wang Haoran in this battle, and presumably his name will appear in the records of war history in the future.

The artillery and gunners on the city wall, and the six trenches under the city, form a three-dimensional defense line, in this case, even if the opponent is dozens of times his own, it is difficult to break through the city defense. Just by uprooting the trenches he set up on the periphery, the enemy would have to throw behind tens of thousands of corpses, and if the other party had such a will to fight, the Ming army would not have been beaten by the rogues and Jianyu.

But after laughing, Wang Haoran felt a little uneasy in his heart. If something goes wrong with the first use of trench tactics, then he will not have a good reputation in the history of war, and he is afraid that he will be regarded as stupid. He was a traditional scholar and valued his reputation in history, so he tried his best to know if he was doing it perfectly.

"Tuanzheng, do you want to drink some water, this weather is really hot!" The orderly next to him handed over the kettle and nagged: "The weather is stuffy, it looks like it's going to rain......"

"Rainstorm ......"

This word penetrated Wang Haoran's mind like lightning, and he suddenly realized that he had neglected something.

Water!

The trenches under the city are low-lying, and if the enemy uses water to irrigate them, what will they do?

After the opponent tried to attack once, they didn't make any moves, could it be that they also thought of this?

Wang Haoran felt that he was suddenly a little out of breath, and he repeatedly warned himself that he must be calm, but his heart was still pounding.

"How to be good, how to be good?" (To be continued)
