In fact, even if it is half a city, it still underestimates Liu Lang after all.

From the moment Liu Lang learned that all the Japanese baggage warehouses had been captured, he had already made up his mind for a great retreat from Chengde.

Yes, in order to prevent the return of the main force of the embarrassed Japanese army from causing the tragedy of the slaughter of a country's capital in the former time and space in advance, Liu Lang wanted to carry out a city-wide retreat unprecedented in modern Chinese history.

In fact, when Liu Lang led three regiments to fight against Luo Wenyu and the Eighth Division after the war, Liu Lang's anti-slope tunnel tactics and the tactics of using night to sneak attack the enemy's heavy artillery positions were unanimously praised by the generals of the north and even the generals at all levels of the Central Army. Even Liu Lang and the remnants of the Eighth Division blocked the Northern Military Commissioner's ten orders to withdraw troops during the confrontation at Rehe, and many generals thought that that was Liu Lang's only choice at that time, and it was very likely that the Eighth Division would bite back if the situation was not stable, not to mention that it was possible that the main force of the Japanese army on the Pingjin front would be blocked north of the Great Wall.

In their opinion, when the two armies were fighting, Liu Lang had to stubbornly protect the nearly 20,000 civilians in Chengde, or the greedy behavior of emptying the Japanese army's supplies, either way, it was really stupid.

The massive amount of supplies and civilians will definitely become a big burden, a burden that can lead to the annihilation of the entire army at any time.

Generals who had not experienced the history of the past planes and planes clearly did not know what kind of beast army they would face now.

Maybe when they look at this battle more than ten years later, they will definitely make diametrically opposite evaluations of Liu Lang.

The 14 years of China's unyielding resistance to the enemy were also the 14 years when Chinese civilians were slaughtered by the Japanese invaders, and the more than 30 million military and civilian casualties counted after the war were only statistics with written records.

Those brutality who were slaughtered by the Japanese invaders, the entire family, the whole village, and the whole village in the mountains and wilderness, and then burned to the ground, were submerged in the long river of history, and countless white bones were found decades later, and the evidence was all pointed to the Japanese invaders who once wreaked havoc on the land of China.

Therefore, Liu Lang ordered Chen Yunfa to send Niu Er to pretend to be a subordinate to send false information, and then completely annihilated Li Shoushan's Fengtian Independent Brigade to scare away the entire Eighth Division.

Yes, the escape of the Eighth Division was completely expected by Liu Lang, and it can even be said that he did it on purpose, if he did not scare away the Eighth Division that still had more than 10,000 troops, it would not be so easy for the people of the entire Chengde City to leave, as long as the Japanese army sent a few infantry squadrons to intersperse behind the Great Wall Regiment, the Great Wall Regiment with insufficient troops would also have to take care of one or the other, and even suffer heavy losses as a result.

If Tanibe Terube had been a little smarter and used 20,000 people as a cover to fight the Great Wall Regiment in close combat, the final outcome of the Great Wall Regiment and the 20,000 people of Chengde would have been extremely tragic.

Fortunately, Liu Lang used the strength of capturing the Japanese army's baggage and ambushing Li Shoushan in World War I to intimidate Gube Terubei, and the Great Wall Regiment not only had the main force that could chase him everywhere, but also had a force that could block his back road at any time.

Tanibe Terube was directly frightened, and ran out of more than 50 miles in one night, which was already 130 miles away from Chengde. The main force of the Great Wall Regiment temporarily led by Qi Guangyuan was still making an all-out pursuit, and the Eighth Division would continue to retreat to the middle of Rehe, and Liu Lang had finally gained precious time to evacuate the entire city of Chengde to the Great Wall Mountains.

In fact, when military historians studied this war after the war, they also had to sigh at the good fortune of the Great Wall Regiment and the 20,000 people of Chengde.

The reason why the whole retreat was successful was also entirely due to the extremely bad weather during this time, the Japanese reconnaissance planes could not take off, and Tanibe Terube had no idea that the excellent Chinese commander in his eyes would be impulsive enough to move the whole city of Chengde.

If he could have known that Liu Lang would be on the road with 20,000 slow-moving Chinese people, he would definitely divide his troops and attack this huge crowd. The Great Wall Regiment was originally an invincible tiger, but the moment they carried the huge burden of 20,000 Chinese people, they became an overwhelmed sick tiger, and even the wounded wolf of the Eighth Division, which was already extremely weak, could tear open a fatal wound on their body.

It's a pity that in that era when there were no satellites, Terube Tanibe, who was busy running for his life, couldn't see that the dangerous opponent he thought was doing an extremely "stupid" and "stupid move mountains" greedy move.

The entire 240,000 catties of grain were summoned by Sun Yongqin and nearly 3,000 mountain people carried 60,000 catties overnight and sent them to the mountains 30 miles away. The crowd was like ants transporting the Eighth Division's piles of wartime supplies, from guns to bullets to shells, into the mountains.

Liu Lang provided 2,500 Type 38 rifles, 20 Taisho 11 young machine guns, 6 Type 92 heavy machine guns, 20 grenadiers, 3 mortars, 2 infantry guns, 3,000 Japanese-style grenades, nearly 1 million rounds of various machine rifle bullets, and 5,000 shells of various types to the Anti-Japanese National Salvation Army established by Sun Yongqin more than 10 days in advance.

But this is still only a fraction of the materials seized.

Even, Liu Lang left Cai Dadao, Shi Datou and Niu Er as tactical instructors of Sun Yongqin's Anti-Japanese National Salvation Army, and they will return to the independent regiment station after training the Anti-Japanese National Salvation Army for half a year, and at the same time there is a Japanese-style radio station for the liaison between the three special forces and the regiment headquarters.

Except for Liu Aba who somehow had to choose to go south with the Great Wall Regiment, the remaining nine puppet soldiers who were captured by the bandits rookies all chose to join Sun Yongqin's Anti-Japanese National Salvation Army, and Sun Yongqin was overjoyed and asked them to serve as instructors at all levels of the Anti-Japanese National Salvation Army.

The Anti-Japanese National Salvation Army, which was completely armed by Liu Lang with a large number of captured Japanese weapons, was much more powerful than the Anti-Japanese National Salvation Army that had fought with birds in time and space, and Liu Lang believed that this time they would not be wiped out after only two years of fighting.

In the face of such a regular army active in the mountains of Rehe, even if the Japanese invaders occupy Rehe, they must be anxious!

Of course, this cannot be said to be Liu Lang's strategic layout in northern China in advance, he is only a small regiment leader now, and he can't think about it that far.

Liu Lang simply hoped that the flame of resistance against the Japanese invaders left in the north was strong enough that it would not be extinguished so soon.

At the moment of the full-scale invasion of the Japanese invaders, there were beacons everywhere, which was the best answer of the Chinese to the invasion of the invaders.

The fight against the Japanese is not a war for Liu Lang alone, but a war for the whole of China.

If one person does not retreat, ten thousand people will not retreat; If 10,000 people do not retreat, then 10,000 people will not retreat;

What Liu Lang wants to do, that's all.
