After introducing the background of the battle, Marine Corps Commander Qian Tieshan pointed out: Although there are still two full months before Amin withdraws from Lengkou Pass in history, it is best to launch an attack on the Qing troops at the end of March and early April.

Because from the end of March, the counterattack troops led by Sun Chengzong will start to gather sentinels from Jizhou, and then deploy troops from the east and west, and finally attack in May, encircling the left and right, and driving away the Houjin cavalry guarding several cities in one fell swoop.

Qian Tieshan's plan was unanimously agreed upon by the participants: to cut off a sufficient number of Tartar heads before the Ming court's "recovery army" regained the lost territory, which was originally the established route, and there was nothing to hesitate about.

The traversal didn't want to have anything to do with those Qinwang troops. This group of people seems to be huge, but in fact, the source is complex, and the ability to fight for merit is extremely strong, and it is trouble.

Therefore, in the next ten days, the northbound troops entrenched in Tianjin Wei continued a series of intense pre-war preparations.

Not only did this include stockpiling a large number of supplies, but the three hundred new soldiers also seized the time to start riding special training, and the horses were restless, and one by one they were tied to the back of the horses and vomited their intestines.

Although these 300 people did not need to go to the battlefield in the plan, as the general reserve of the campaign, it was necessary for the members to learn to ride horses, and at least they had to reach the level of mounted infantry.

In this process, Cao Zongbing also had a pen-and-ink lawsuit with a court bigwig - the secretary of the military department, the scholar of the Zhongji Palace, the governor of military affairs inside and outside the capital, and Sun Chengzong and Sun Laoqi.

It is said that after a certain general soldier did not leave Tianjin under the banner of King Qin, he didn't care about the capital at first: the soldiers and horses of King Qin, who gathered near the Beijing Division before and after the Jisi Change, claimed to have 400,000 soldiers, but in fact there were still 200,000 or 300,000 people.

That changed after March.

Due to the retreat of the Later Jin army, the capital began to open its gates one after another, so the density of information transmission between the military headquarters and various places returned to the previous level.

In this way, Comrade Sun Chengzong, who was promoted to the secretary of the military department by Chongzhen's firing line, finally noticed not long ago that Cao Zongbing's list of meritorious service in Tianjin had come, and there was a civilian official's signature on it, which showed that the merits were all true.

So Sun Laoqi ordered that Cao, the deputy chief soldier of Zhangchao, immediately led his troops to Jingyuan to listen to it.

Then a few days later, Cao Zongbing's official document came. The official document said this: Because of the previous battle with the Tartar soldiers, Cao Zongbing personally went into battle, "his body was wounded by seven wounds", and the blood flowed all over the ground, so the general soldier was recuperating from his injuries at the moment and was unable to move.

In addition, there are too many southerners here, and most of them are sick, so they can't come to Beijing to participate in the battle for the time being...... Cao Zongbing promised that once his body improved, he would immediately come to the command of the adult to listen to the order.

Normally, Sun Chengzong would have passed after reading this official document, but this is not the case. Since Mr. Cao's official documents in Tianjin came, then other people's official documents could also come, and there were some personal letters in between. So Lao Sun Tou quickly figured out what Cao was doing in Tianjin.

In this way, Lao Sun Tou was full of interest in this General Cao - he came from thousands of miles to the sea, but after arriving at the station, he stayed in Tianjin; said that he was the king of Qin, but he made a big deal until the emperor ignored it, saying that he was here to mess around, but he led troops to attack the Tartars......

I can't guess you?

Fortunately, the old grandson is experienced, and as soon as his brain turns, he thinks he has seen through Cao Zongbing's heart, liver and lungs.

Lao Sun Tou does have a lot of experience in dealing with warlords.

Not long ago, when Yuan Chonghuan was taken down by Chongzhen on the gate tower of the capital, Yuan Chonghuan's close comrades-in-arms, the core leaders of the Liaoxi Jiangmen Group, the traitors in the late Ming Dynasty, the boss of the Liaosheng Group, and the ogre ancestor Dashou Comrade were also "sweating like pulp".

What's next? Comrade Zu Dashou came down from the city gate with his front foot, and ran away with his army with his rear foot...... Yes, Zu Dashou once again gave full play to Guan Ningjun's ancestral skills, and sold his teammates and ran away at a critical moment.

This time it was the emperor who sold.

At this juncture, Sun Chengzong, who had been supervising Ji Liao and presided over the construction of the Guanning Jin Defense Line, hurriedly wrote a letter to persuade Zu Dashou, who had already run halfway.

However, even so, Comrade Zu Dashou stayed in Jizhou, and never set foot in the capital again for the rest of his life.

Therefore, the old grandson, who has been dealing with the warlords of Liaoxi for almost half his life, still knows the thoughts of the military head relatively well - while dealing with the imperial court, he maintains his independence at any time, and if there is a slight disturbance, the master will not serve.

So although the two sides have never met, Sun Chengzong now thinks that he still has research on Cao Zongbing, the former Haikou: and Zu Dashou and his ilk are all the way, compared to Zu Dashou, Cao is nothing more than a warlord.

In addition, there is another point that makes Lao Sun Tou particularly interested in Cao Zongbing: generous.

In Lao Suntou's impression, except for the Guanning Army, which swallows a large number of imperial court revenues every year, there is no martial artist in the world who is not a poor ghost.

Some of the generals are to support their families, and some are simply to live a luxurious life for their own promotions and fortunes, so they wantonly deduct the food of ordinary soldiers, resulting in low combat effectiveness and no fighting spirit among the troops.

However, judging from some information received by Lao Sun Tou recently, this chief soldier from the south, wherever he went, businessman Jia Jingcong, and the southern goods rolled in, as if he was a contemporary Tao Zhu's posture.

Therefore, Lao Sun Tou wanted to have more contact with Cao Zongbing: the military leader, who is unique and can support himself, is a figure worth exploring more than Guan Ningjun in the long run.

So Old Man Sun took up the pen and wrote a letter to Cao Zongbing.

The content of this letter is very appetizing to the warlord: Lao Sun Tou not only warmly encouraged Cao Mou, who was born in a reckless manner, but also solemnly expressed his appreciation for the spirit of this Qianli Floating Sea King.

At the same time, Lao Sun Tou also made a promise in the letter: as long as Cao Zongbing can make new contributions in the follow-up Qinwang Campaign, then he will definitely ask for credit for the general in front of the emperor, which is the due treatment of the humerus of the imperial court.

As a result, Lao Sun Tou's sincere letter was finally exchanged for General Cao's rhetoric, but it was a little more polite: when the southern soldiers in his hands are healed, Cao Chuan will raise troops to the north and fight to the death with the Tartars, in order to repay the love of the bachelor.

When things get to this point, Sun Chengzong has no choice. The reason why the imperial court was able to mobilize the world's troops was nothing more than grain, grass and silver. Now that the surnamed Cao is not short of silver, it is impossible for Sun Chengzong to mobilize this army, and people can stay in Tianjin for as long as they want.

So the first contact between the two sides ended hastily - Lao Sun Tou led hundreds of thousands of troops, and he didn't have the time to spend it with Cao Zongbing. And the traversal side is also making pre-war preparations, and everyone is very busy.

..........................

In a hurry, ten days passed.

On the 25th of March, flags were unfurled on the old school grounds, a phalanx was erected, and a mixed force of 1,000 Imperial soldiers and indigenous cavalry participated in the pledge meeting with full morale.

Chief Cao Bing, who was sitting on the podium, and Zhang Zhongqi, the newly appointed commander of the Flying Tiger Battalion, spoke respectively.

The content of the speech is very vulgar, nothing more than obeying orders and listening to commands, the general will not treat everyone badly, he wants silver to have silver, and he wants official positions - General Cao promised that this time, the Flying Tiger Battalion will not be disbanded, and the adults will spend silver to support everyone, and the days of bathing and eating pig's head meat every day and paying salaries on time will continue.

There was cheering on the school grounds.

Indigenous soldiers were convinced of this rhetoric. The encounters in the Flying Tiger Camp during this period gave them a deep understanding of Cao Zongbing's ability to fulfill his promises. So in today's old school field, the murderous spirit is shocking, roaring again and again, and the soldiers are full of horses, and everyone is waiting to kill the Tartars and make contributions.

The change in mentality of the indigenous soldiers was incredible even to themselves.

At first, these people thought they were the kind of auxiliaries who were huddled in the rear and could run away at any time. As a result, after training and fighting in this completely different barracks for a while, their ability to run has increased greatly, but now everyone is eager to go and do a few Tartars to drink......

The Ming people didn't know what the army's organizational ability was, but they really felt the improvement of their ability and the change of mentality, which in today's school field, have been transformed into the confidence that the Ming army lacks the most, fighting the enemy.

So, after the last slogan was sounded, thousands of people ...... The army marched out.

The so-called soldiers and horses have not moved the grain and grass first. In fact, the day before the pledge meeting, the supply convoy composed of fifty carts had already set off in advance.

From Tianjin to Yanshan Yumai in the north, the distance is 150 miles. According to the plan, the large convoy will be shuttling between the two places without being harassed to provide supplies to the troops.

In this way, unless there are special circumstances, the soldiers of the Flying Tiger Battalion can be put into battle as a whole and do not have to carry grain and grass back and forth.

The large force of cavalry that had set out from the school yard overtook the large convoy in the middle of the day and rushed straight north.

This time, Qin Wangjun, on the surface, was Cao Zongbing himself, but in fact, Zhang Dongdong went back after going out of the city for a circle. His forte is to sit in the center and deal with various forces, and the march and war have nothing to do with him.

It is Qian Tieshan who is really responsible for commanding the troops, and the newcomer Zhang Zhongqi will take over the Flying Tiger Battalion as the deputy of the general army on the surface. After the war, he would exchange his merits for the rank of high-ranking military general, so that he could stay in the north in the future.

The order of departure of the entire contingent was in the order of the special combat team, the Flying Tiger Battalion, and the Guards Battalion.

Although the establishment of the Flying Tiger Battalion was still a brigade of five hundred, after this departure, the communication between the teams was significantly strengthened, and the soldiers were told that everyone would gather as a whole group to fight at any time.

Then early the morning of the second day after departure, the Flying Tiger Battalion all rushed into the Yanshan Yumai in the north. The soldiers began to scatter and search the mountains under the command of the radio, without any scruples - the main force of the Eight Banners has already been released, what are they afraid of at this time?
