The Eight Banners Han Army was a firearms unit in the Qing Army, but this firearm unit was more of an artillery unit, although it was also equipped with firearms such as bird guns and three-eyed guns, but the most were all kinds of artillery.

The Han army has more than 100 red-coated cannons, and most of them are more than 10-pound guns, while the large and small Franc machines are equipped with more than 1,000 pieces.

The Francois was equipped in various armies in this land, and Suarez was no stranger to it, and many of the Shun troops also used it.

Tang Tong explained the Han army flag firearms he had seen, except for the number that was a little surprising, the rest was nothing, Suarez even said that in an artillery battle with light artillery like the Franc machine, the four-pounder field gun could easily defeat, but the problem was that the Qing army did not only have the Franc machine gun.

"I sent a few people to spare the forest last night to investigate, although a few were damaged, but I also found other movements of Dongyu, that is, the shield car, Dongyu's shield car and the Han army flag together have also arrived, and my subordinates also found that they are reinforcing and manufacturing new shield cars, a lot of them, maybe dozens, maybe hundreds." Tang Tong said.

Zhang Nai smiled slightly, with disdain at the corner of his mouth: "It's just a shield car, it's not difficult to destroy." ”

Tang Tong immediately responded solemnly: "Yihou, although all armies use shield cars, but the shield cars of the Donglu are different from the Ming army, if you use the method of breaking the shield cars of the Ming army to deal with the shield cars of the Dongyu, I am afraid that you will suffer a big loss." ”

Bounce up the shield car, the most used, or the Ming army, the Ming army often set up a car battalion to fight, Zhang Nai and the Ming army have been dealing with for many years, so he is very disdainful of this, but what he doesn't know is that the shield car of the Ming army and the shield car of the Qing army are not a thing.

The shield cart of the Ming army originated from dealing with the Mongolian cavalry on the open ground, the Mongols only had bows and arrows, and the guns of the Ming army were easy to disturb their horses, so the wooden planks used by the shield carts of the Ming army were relatively thin, usually one inch thick, and there were even light carts with a thickness of only six points during the ten thousand years.

However, the shield vehicles of the Qing army were used to deal with the firearms of the Ming army from the beginning, so they highlighted a strong defensive force.

Its structure is relatively simple, the most important structure is the huge wooden shield of the tree on the two-wheeled vehicle, this wooden shield can cover more than 20 people, only five or six inches of wooden planks, and add cowhide and iron sheet to form a three-layer composite structure, the small cannon that shoots shotguns such as the Franc machine and the tiger squat cannon cannot break through its defense, and the bird gun, the three-eyed gun and the like are even worse.

Only artillery over three pounder could effectively deal with shield carts, and they had to be solid shells, so the Shun army had no weapons that could break the shield carts except for Suarez's four-pounder cannon.

"It seems that the Tatars have some tactics and special weapons against firearms, but I don't think it's a big deal, their artillery is basically not a threat, because we can put the infantry under the embankment, just hide it in the anti-slope, and their artillery cannonballs can't hit our soldiers," Suarez said.

As for the shield carts, we can smash some stakes into the ground to slow down their advance, give my artillery more room to play, and smash their shield carts one by one with solid bullets. They have reinforcements, we have reinforcements, and although we are still at a disadvantage, we have a geographical advantage.

Well, the only problem is that I have only half of the shells left. ”

Suarez's artillery company was accompanied only by artillery trucks and ammunition trucks, so each gun only carried about fifty shells, and the supply trucks were too heavy, so they were stranded in Tongzhou.

Zhang Nai looked at Tang Tong: "General Tang, what do you think?" ”

"Maybe we can retreat to the other side of the river, the enemy's shield carts will definitely not be able to cross the river, so their artillery and shield carts will be useless." Tang Tongxian was very conservative, after all, the infantry involved in this battle were all his men, and in the case of the results already achieved, he hoped that the casualties would be as few as possible.

Zhang Nai did not respond, but looked in the direction of the enemy and entered into thought, Tang Tong and Suarez both looked at him, hoping that he would accept his suggestion. Suarez's tactics have big results and big losses, and once he wins, he can even counterattack the enemy, while Tang Tong's method has small results, and the losses are definitely small, and there is no chance to expand the results.

"Actually, it doesn't make much sense to choose, the enemy who entered the Kou is a partial division, and the drama on the Gubeikou side will not be punctured for a long time, and it is a matter of time before we retreat, but the brothers of Modaoyu can't be saved." Zhang Nai said lightly, with a slight helplessness in his voice.

"Huh?" Tang Tong exclaimed in surprise: "Sharpening Daoyu? Are you worried about the defenders of Sharpening Valley? ”

Zhang Nai nodded, and Tang Tong said: "They have fled back, there are more than 140 men, women, and children, and I arranged for them to enter the baggage camp, in addition to them, my people also collected more than 300 refugees who were taken away by the Horqin people." ”

"Are you sure? When was this? Zhang Nai asked in surprise.

Tang Tong first instructed his soldiers to call a few people from Modaoyu, and then said: "The people from Modaoyu arrived in the second half of last night, and the refugees arrived one after another from yesterday morning, and now there are still people coming." ”

"Why didn't you tell me?" Zhang Nai looked at Tang Tong.

Tang Tong didn't know how to answer, he didn't care about the life and death of these defenders and the people at all, but Zhang Nai was very concerned, in the early days of the peasant army, betrayal, surrender, and fear of war were endless, until Li Zicheng became the king of Chuang's serious military discipline, this army did not change, but for Guan Qi and other soldiers who were trapped in a lonely city and caused casualties to the enemy, Zhang Nai, who was from a humble background, was extremely appreciative, on the contrary, the Ming army betrayed each other and pitted each other It was very common, and the battle of Songjin, Tang Tong would have lost on the battlefield if he had not thrown away the friendly army and ran fast.

Therefore, Tang Tong is not a person who sharpens the knife, nor is he a cronie, it doesn't matter if he is dead or alive.

Not long after, Guan Qi and You Yu were brought to Zhang Nai, and the two of them revealed their identities and told them how to get out.

When the camp of the Horqin people was attacked by Tang Tong's own soldiers, Guan Qi and You Yu knew that reinforcements had arrived, but they could not be contacted, and during the day, they heard the rumbling of artillery here, and guessed that the reinforcements and the enemy were fighting, both of them felt that the opportunity was rare, so they were ready to retreat, they first loaded some property into the carriage, and ran out during the day, and were intercepted by the cavalry of the Horqin people, so they retreated to Modaoyu, and when the Horqin people controlled the carriage and robbed the property, the gunpowder inside exploded, killing more than a dozen people.

Therefore, when Guan Qi and You Yu fled with the people for the second time, the Horqin people did not dare to approach.

They have always thought that there are 300 soldiers in Modaoyu, plus the people, maybe thousands, thinking that the number of people who escaped is only a small part, but they ended up with an empty city.

"How did you find here?" Zhang Nai asked.

Guan Qi said: "We walked around the mountains to the north for one night, crossed the river from upstream, and came through the forest. With the old and the weak and the injured, Yu Yu came directly through the forest at the bottom of the mountain, came from the side of Baishitan, joined us, and a dozen people, took the safest route, went north to Lin Quanzi, and found this place again, so it was not long after arriving. ”

"Wait, there are more than 100 of you, and you are divided into three ways." Zhang Nai felt a little strange, because there were the old and weak and the wounded, Yu Yu took the most dangerous but most convenient road, Guan Qi took the safer one, and the most cautious people, the farthest detour, was also the safest.

"There are a lot of trails here, so it's easy to escape," Guan said. There are also many people who are familiar with the terrain ........ Speaking of this, Guan Qi avoided Zhang Nai's eyes, but Zhang Nai asked seriously, promising not to blame him, and Guan Qi gave the answer.

It turns out that the wall is not only the side wall of the Ming Dynasty, but also the distribution center of smuggling, a large number of salt, iron, cloth from here into the territory of the Mongols every year, there are many people who come and go, and there are many people who are familiar with the road, and whether it is Modaoyu or those locals who were captured, they mostly make a living by smuggling, so after getting free, they immediately found their familiar path and fled.

"Okay, you go and rest, from today onwards, you will follow me." Zhang Nai said to Guan Qi and the others, and after sending them away, Zhang Nai said: "General Su, let your artillery retreat to Horseshoe Bay, General Tang, transfer the rear team, after dark, we will retreat." ”

Tang Tong listened nervously to Zhang Nai's dispatch, and thought that Zhang Nai's would continue to fight, but he didn't expect that the final order was to retreat.

"If we're going to retreat, what are we going to do with the rearguard?" Tang Tong asked.

"When the rear team comes, the East will think that we will continue to fight, so that the retreat at night will be smooth." Zhang Nai said lightly.

There are two reasons for Zhang Nai's retreat, one of which is that it is of little significance to fight any longer, his own forces have no advantage, it is difficult to achieve a decisive victory, and he has to risk the empty city plan of Gubeikou being discovered. The second is that Guan Qi and those refugees can escape back, which shows that there are too many hidden paths nearby that he doesn't know, and the enemy is likely to copy his own back roads around these paths, which is why he wants the rear team to follow.

Maybe the Horqin people and the Dongyu didn't know these paths, but the local people knew, and more importantly, the scouts sent out by Zhang Nai and Tang Tong found that the Horqin cavalry was nowhere to be found, and Zhang Nai didn't know that Manzhu Xili was a guy who only wanted to rob and make a fortune, and didn't want to lose it, and had withdrawn from the side wall. Zhang Nai could only think about the departure of the Horqin cavalry to the worst, maybe they had already begun to go around the rear.

Four days later, Zhang Nai successfully led the team back to the starting point of Tongzhou, Miyun also gave up, and after handing over the troops to his deputy, he immediately went to the capital, and informed Li Zicheng and the high-level of Dashun about the experience of this trip and the battle with Dongyu.

"Your Majesty, Gubeikou and Qiangziling have lost ........" Zhang Nai entered the Qianqing Palace, which has become the command center of Dashun, and there is a military atmosphere.

"Yihou, don't panic, drink saliva, we have time." Li Zicheng had already learned the general situation of the battle of Modaoyu from the Tang newspaper, and the beheading of more than 400 was not a big victory for a force like Dashun with an army of more than 400,000, but it boosted the morale of the army and proved that Dongyu was not invincible.

As a result, Li Zicheng was extremely satisfied with Zhang Nai, and the army also spoke highly of him.

Liu Zongmin pointed to the map and told Zhang Nai everything that was happening now from the perspective of the overall situation: "Now a main force of Donglu has entered from Xifengkou, the number is about twenty or thirty thousand, Jizhou has been lost, Dongyu occupies Zunhua, on this basis, sweep the periphery, our cavalry has had large and small battles with them, and the losses are not small.

The last news sent by Gubeikou showed that, as Yihou guessed, this was indeed the main entry route of the Eastern Prisoners, and it was mainly Manchuria, which had entered the customs and occupied Miyun.

We can't be sure for the time being, but obviously, more than 100,000 is certain. ”

"What about Wu Sangui, his attitude?" Zhang Nai immediately asked, he thought it was the key.

"This guy is watching from the wall." Li Zicheng said lightly, and some ruthlessness flashed in his eyes.

But Zhang Nai immediately said: "Your Majesty, this is already a very good situation, we should probably release more kindness, such as sending Wu Sangui's remaining relatives back, and giving him some silver and so on." ”

Song Xiance said with a smile: "The emperor has sent 40,000 taels of silver in the name of preparing for famine, and Wu Sangui accepted it, but Wu Sangui refused the rest of his relatives. ”
