Starting from the next day, Li Qinglin focused on training the infantry squad's offensive and defensive tactics.

At this time, the squad platoons of the National Army were also learning from the German army. They all assumed that the squad platoons of the attack after strong firepower were prepared, and the formation was relatively dense, which was not in line with the actual situation on the Chinese battlefield at all.

The tactic proposed by Li Qinglin was not invented by him, but he saw the strength of the Japanese wave attack on the battlefield these days, and then recalled the famous tactics of Marshal Lin of the Communist Army, such as "one point and two sides", "three systems", "three fierce", "four fast and one slow".

This tactic is actually mainly learned from the Japanese combat methods. Specifically, it is to divide the whole class into three groups, each group of four people. Each group is commanded by a group leader, and he himself commands three group leaders as the squad leader. When the whole class attacks, one group advances, two and three groups of covers and shoots; when the first group reaches the predetermined position, the second group advances again, one and three groups of covers, and repeats itself in a cycle. The three groups cover each other on the battlefield, attack alternately, and advance in a wavy manner of jumping and undulating waves. Although the actual number of attackers is not large, the pressure on the enemy has never decreased.

When Li Qinglin first saw this Japanese attack method, he was shocked. At that time, he believed that the Japanese army adopted the "one-one-two-sided" and "three-three-system" squad-platoon offensive tactics. Li Qinglin even believed that Marshal Lin's tactics were borrowed from the Japanese tactics, but after refining the Japanese tactics, he taught them to the soldiers in a simple and easy-to-understand way.

As soon as Li Qinglin proposed this tactic, he received the firm support of Xiao Liuzi and Li Gousheng, because they had seen the powerful power of this offensive method.

While other classes were still busy with guns, bombs and assassination training, Li Qinglin and the others had already focused on practicing group offensive and defensive tactics. The platoon leader had also seen the power of the Japanese offensive. He stared at the side for a while, and finally praised it with his thumbs up.

Although Li Qinglin and the others are stepping up their pre-war training, the war did not leave them more time.

In the early morning of August 23, the 57th Regiment of the 10th Division concentrated its forces to launch a counterattack. The Japanese position on the opposite side had been broken and the Japanese army had been defeated. Wei Lihuang ordered the 57th Regiment of the 10th Division to take advantage of the victory to attack and advance towards the border to meet the 13th Army.

The company commander hurriedly arrived and ordered all officers and soldiers to gather immediately, and the troops marched urgently towards the border of the town.

In fact, not only the 57th Regiment encountered the Japanese army's blockade, but the other regiments exchanged fire at about the same time. The purpose of the Japanese blocking troops was to gain time for conquering Nankou.

On August 22, other troops had already broken through the Japanese positions. In order to reinforce the 13th Army as soon as possible, they didn't even have time to clean the battlefield. The troops lost some of the baggage, and the officers and soldiers advanced lightly, and only carried the necessary weapons and ammunition with them to run forward.

Starting from August 22, heavy rain fell. The heavy rain made the mountain roads slippery and difficult to move, and people in the team fell and fell from time to time. However, heavy rain also brought one benefit to the 10th Division, that is, the Japanese planes could not take off, and they could not reconnaise or bomb the 10th Division.

On August 23, the main force of the 10th Division arrived at Qingbaikou. Qingbaikou is a ferry on the Yongding River and is a must-pass place for the 10th Division to reinforce the border troops.

Usually, the Yongding River has little water and is not deep. Generally speaking, soldiers can wade through the river. However, the heavy rain caused the Yongding River to soar. To cross the river, you must use a boat to cross the river.

Li Mo'an immediately ordered: The 10th Division was scattered and forced to cross.

After crossing the river, the 10th Division continued to forcibly marched, and the south entrance was already close.

Just when everyone thought the task was completed, the 10th Division encountered a blockade from the 11th brigade of the Japanese army a few kilometers west of the south entrance. Both sides of the enemy and us suddenly met, and neither set up a solid position. The battle between the two sides was extremely fierce.

Judging from the fire exchange, the 11th Brigade of the Japanese Army was also at the end of its strength. Wei Lihuang ordered the radio station to call the Tang Enbo's troops guarding the Nankou, hoping that they would cooperate in combat, attack forward and backward, and annihilate the current enemy in one fell swoop.

But no matter how the radio calls, there is no answer from the Thirteenth Army, and the Thirteenth Army can no longer contact you.

Wei Lihuang deserves to be a tiger general of the national army. He immediately ordered: No matter whether the 13th Army cooperated or not, the 10th Division must enter the border.

Because the 527th Regiment finally broke through the Japanese position, they became the guards of the entire division. Because Li Qinglin and his second battalion were just reorganized, they were arranged to be the reserve team, so the battles on the march were not as good as theirs. However, this was good for the recruits, and they could slowly adapt to the war environment.

The heavy rain also destroyed the roads. Japanese tanks and armored vehicles were unable to assist, and the planes could not take off and bomb. The 10th Division made a concerted effort and each unit attacked continuously. One of the 10th Division finally attacked the town west of Nankou on the afternoon of the 26th, and the other occupied the village near Nankou.

But these two places were empty, and the people had long disappeared, and even Tang Enbo's troops were gone.

Wei Lihuang ordered the troops to be vigilant and stand by on standby, and at the same time asked the radio station to contact the Nanjing Command. After a long time, he received a reply, saying that Tang Enbo's troops had evacuated on their own!

Since Tang Enbo's 13th Army fought back with the Japanese army on August 7, although they fought hard, their weapons and troops were not as strong as the Japanese army, so they suffered heavy casualties and the front line was in danger.

Tang Enbo received news on the 21st and 22nd that the reinforcements of Wei Lihuang's troops were blocked by the Japanese army, and his heart began to shake. At the same time, his left-wing Liu Ruming's troops were also attacked by the Japanese army in Wanquan and retreated to Zhangjiakou on the 23rd.

On the 25th, the Japanese army attacked Hengling City and the Badaling Great Wall. At this time, Tang Enbo thought that there was no hope of reinforcement, and all the reserves in his hands had been put into battle, and his left wing no longer existed. At this time, the Japanese army's fierce attack made him even more panic, so he issued an order in the early morning of the 26th: the troops retreated on their own at 1:30 pm on the 26th.

The National Army guarding Nankou has retreated, but the troops have not yet left contact with the Japanese army during the evacuation, and the transferred troops are still fighting hard with the Japanese army coming from all directions.

On the 27th, the 11th Brigade of the Japanese Left-wing Fifth Division and the 11th Brigade of the Independent Mixed Mixed Brigade had occupied Huailai and Yanqing near Nankou respectively. In addition, the aviation troops of the Japanese Xiangyue Qingshi First Army, the artillery troops had already been eyeing the 10th Division, and the 10th Division had the possibility of being surrounded and annihilated by the enemy.

Wei Lihuang, who was on standby, had no targets for reinforcements, and his troops might be surrounded and annihilated by the enemy. On the 29th, Wei Lihuang ordered the reinforcements to stop and the troops retreated.

Li Qinglin's squad did not participate in the battle during this period. They had been spending the forced marching, but Li Qinglin did not relax the pre-war training for the new recruits. On the way of the marching and in his free time during rest, Li Qinglin, Xiaoliuzi, and Li Gousheng all wanted the new recruits to repeatedly explain the key points of grouping tactics.

Grouping tactics are just a reasonable combination of individual tactics. The most important thing is the mutual trust and cooperation between combatants.

The recruits were also trained by the recruit battalion and had received the most basic individual combat training. However, lack of culture is a common phenomenon among the recruits. Their acceptance ability is indeed very poor. After repeated emphasis, the recruits finally mastered the most basic theory, and the actual effect must be tested in combat.

Faced with this situation, Li Qinglin couldn't help but sigh in secret: It was still Mao Taizu who was talking about the truth, and an army without culture is a stupid army!
