After a life-and-death battle led by the special forces of the Independent Regiment and the reconnaissance elite soldiers of the 20th Infantry Wing of the Japanese Fourth Division, a larger-scale offensive and defensive battle between China and Japan with thousands of men each began.

After the arrival of more than 3,800 troops in the 20th Infantry Wing, it only took more than half an hour to repair and launch an attack on the Lianhua Mountain position where Sun Yongqin's unit was located, under the cover of four mountain guns and four infantry guns of the artillery squadron of the wing.

Although the Japanese soldiers suffered heavy casualties, they did not say that they did not play a role at all, and they finally detected the position of the peasant army active in the defensive position of the Huanghuachuan generation in Chengde.

Of course, this is also the result of Liu Lang's deliberate release of water. If they don't know about the defensive position of Sun Yongqin's troops, how can they let the horses attack? If you don't attack, how can you let these peddlers of the Fourth Division knock off their front teeth?

Throughout the history of China's Anti-Japanese War, the characteristics of the Japanese army's divisions and regiments are actually similar to all kinds of dog tempers in Liu Lang's opinion.

For example, the Fifth Division under the leadership of Seishiro Itagaki who is full of militaristic thoughts, they are like a wild dog, the harder you beat them, the more crazy they become, and even if they are dying, they will bite and make your heart ache, and they are a difficult opponent. Another example is the 16th Division of the Japanese Army, which committed heinous crimes in Nanjing, it was like a mad dog, and in the face of a crisis, he didn't care about his own safety at all, and he had to tear off a piece of meat on an opponent who was much stronger than himself. The 16th Division, which was surrounded by the US army in the Pacific War, was desperate and relied on the bones of its own soldiers killed in battle to fight against the US army, and only more than 600 people remained in the entire division after the war, showing that they were not normal people's madness, and they were an abomination and a very terrible opponent.

But the Fourth Division, in Liu Lang's view, is more like a husky. Don't look at the appearance of a wolf, with cold eyes and sharp teeth, but as long as you beat it up, this thing has to show its life-first nature.

What we have to do now is to beat up this pretentious "Erha" fat first before talking about anything else.

The "husky" in Liu Lang's eyes, under the order of Nagumo Zaoji Daisa, who had lost half of his infantry squadron before the official start of the war, launched an attack on the Rehe Volunteers, who had already dug trenches and fortifications, at four o'clock in the afternoon, which was close to the twilight of northern China's winter.

The reason why Sun Yongqin built his first line of defense in Lotus Mountain was because of the topography of Lotus Mountain. Not because it is dangerous and easy to defend and difficult to attack, but because of the terrain of Lotus Mountain.

Lotus Mountain is not just one mountain, but composed of several mountains.

As the name suggests, Lotus Mountain looks like a blooming lotus flower when viewed from above. In the middle is a 130-meter-high hill that resembles the stamen of a lotus flower, surrounded by four large hills that resemble flower petals, and on the periphery are small mountains that are cascading on top of each other.

Further afield, there are higher and higher mountains, which are the points that must be passed if you want to enter the mountains. And if you want to pass through the Lotus Mountain area, the only mountain road that can take the cart is only 300 meters away from the main peak in the middle of Lotus Mountain, as long as you garrison above, if you want to go from that road, it is within the range of their firepower.

However, if you want to attack the defensive position on the main peak of Lotus Mountain, you can't dodge the attack from the other four mountains, but if you want to capture any of the mountains first, because of the terrain, the defensive position on the hills that are not far away can also support it.

To put it bluntly, according to the characteristics of the terrain, the defensive positions of Lotus Mountain are mountain defensive positions that can be horned into each other, and the positions on the main peak can also protect the flank security of all peripheral positions.

Even if the two mountains outside are captured, as long as the main peak is still behind and the two positions on the rear are still there, all the troops can still retreat smoothly under the cover of firepower, and finally escape into the mountains.

This is the best defensive terrain that can be defended and withdrawn. Although once sent heavy troops up to three infantry brigades, Sun Yongqin did not want to suffer too many casualties and took the initiative to retreat into the mountains to give up this defensive location, but Sun Yongqin's troops can be entrenched here for a long time, it does not mean that the Japanese can also, and as soon as the first mixed brigade withdraws, they will come out to occupy this territory, which makes the first mixed brigade stationed in Rehe very distressed.

If you win the battle, you will use the terrain advantage to carry them hard, and as soon as you see that there are many little devils, we will withdraw. As soon as you leave, you will come back to occupy this area and harass the Japanese army in this area endlessly. In the past two years, there have been three or four hundred Japanese soldiers who have died under Sun Yongqin's troops, and countless property has been lost.

Otherwise, they would not have lowered their faces and asked the Kwantung Army Headquarters to send heavy troops to encircle and suppress Sun Yongqin, who could not kill Xiaoqiang.

The Kwantung Army Headquarters sent more than 7,000 people from the 1st Brigade of the 4th Division to Rehe, hoping to annihilate the increasingly powerful Chinese peasant rebels in one fell swoop with a thunderous force, and never give them a chance to resurrect.

According to the information provided to Nagumo Zaoji by the 1st Mixed Brigade, the Chinese may symbolically defend this area for a period of time, and then retreat and flee. Although Nagumo was angry at the huge losses under his command, he was also prepared to occupy this important place first, wait for the arrival of another infantry wing of the brigade, and then divide his troops into two ways to carry out a long-term encirclement and suppression of the Chinese peasant rebels who had fled into the mountains.

As a top student at Kyoto Army University, Nagumo Shuji knew that the army that had escaped into the mountains was safe for the time being, but it was also a dead end. No army could hold out for long without any supplies, and the mountains provided an endless barrier of protection while also blocking their ability to get supplies.

The reason why the Rehe garrison has failed several times to encircle and suppress the mountains is because they are insufficient, and there is still a rebel army in the outer Qinglong Mountain that echoes here, and they are often stabbed by cunning Chinese on that side before they finish fighting.

But now, here they are, it's completely different.

On the periphery, the Rehe garrison was heavily armed. In the mountains, more than 7,000 troops carried out a tight blockade and sought an opportunity to fight a decisive battle with the main force of the Chinese peasant army trapped in the mountains. Even if they don't dare to show up because they are afraid, then they will be trapped in the mountains.

This trick has long been played by the Imperial Army in the three northeastern provinces, and several large Chinese rebels have been annihilated in this way.

Nagumo's idea was good, but the facts gave him a slap in the face.

The No. 1 position on the left side of the main peak of Lianhua Mountain is stationed the strength of a battalion of Sun Yongqin's department, which is said to be a battalion, but in fact it is only equivalent to a reinforced company of the regular army, and it is less than 300 troops. Because Sun Yongqin has already organized his more than 4,000 people into a division and three regiments, the establishment is large enough, but the manpower is not enough, so he can only change the company into a battalion, and the battalion into a regiment.

More than 4,000 people were organized into four regiments, but each regiment was actually only a little more than a thousand troops. In fact, this is also the old routine of the volunteers in the Japanese occupation area during this period, pulling the tiger skin and erecting a big flag! The banner is erected, and sooner or later people will recruit enough.

You must know that Sun Yongqin only had more than 300 people when he first pulled the team, and it swelled to 3,000 people in a month, and now after two years of so many battles, it is already rare to have more than 4,000 people.

The first position was attacked by a Japanese infantry squadron, flanked by another infantry squadron to contain the Chinese peasant fire on the other hill, and two infantry squadrons in reserve.

The four mountain guns and four infantry guns of the artillery squadron directly under the wing sent by Nagumo Zaoji, as well as the two infantry guns equipped by the infantry brigade that served as the main attack, a total of ten cannons, provided fire support to them.

This momentum is no less than the first battle fought by Liu Lang's Independent Regiment in Luo Wenyu and the Fourth Brigade.
