In the depths of a mountain like Taihang Mountain, not to mention a field radio station that relies on long and short waves to transmit information, that is, in the next eighty or ninety years, if there is no base station, 3G and 4G can only draw a small cross, and it is normal to not receive field radio information.

Kawagishi Bunzaburo couldn't know the battle situation in detail in the area of Shichiwa Village, but he was not as anxious as he imagined. With a field force of nearly 10,000 people, not to mention that the main force of the Chinese is pinned down in the area of Niangzi Pass, even if there is really one army or even two armies with tens of thousands of people? Wasn't Liangfu a pig last month? Can't run if you can't beat it? Open the way with mountain artillery infantry artillery, how can the Chinese take them?

Little did he know that Yoshio had really turned into a roast pig last month, and his reinforcements were also in dire straits. It's about to turn into a roast pig.

Regarding the "flying thunder cannon", which is not a cannon or at most a projectile, Liu Lang actually did not say that he had great confidence, hoping to collapse nearly 3,000 Japanese troops in the river valley with about 500 explosive packs.

That miracle is not replicable.

This river valley is not like the Qiqian Village, in fact, the terrain is quite open, the narrow place is about 200 meters, the wide place is 300 meters, as long as you hide far away, no matter how powerful the explosive bag is, the lethality is limited after all.

However, Liu Lang forgot that the launch of the flying thunder cannon was projected from the top of the mountain, and the range was much farther than that on the flat ground, and the attack area was naturally much wider.

In the first two minutes of the explosive bag flying, the number of Japanese soldiers killed and blown up was 300, and then it gradually decreased.

However, inflicting casualties on the Japanese army is one of them, and blowing up the Japanese army at dusk is the most important thing.

There was an infantry regiment on each side of the hill with a total of more than 4,000 people shooting downward, and the Japanese did not have the courage to rush into the unsheltered river valley.

For these devils who have entered the encirclement, if they want not to be bombed by explosives, they have to hide in a field with only stones and bushes, but if they go there, they will become a live target for Chinese soldiers who shoot condescendingly.

Either they were shot or they were blown up by explosives packets, and the Japanese had to make a choice.

Recruits are afraid of artillery, veterans are afraid of guns. These Japanese troops, who had received at least more than a year of military training in China and fought for at least two months in North China, still made a relatively correct choice and did not blindly run into the field. After the initial panic, under the constraints of the squadron leader and squad leader, he searched for cover along the mountain road and took refuge in the mountain, and also launched a counterattack on the mountain.

However, the lower part of the mountain is mostly bare rocks, and even weeds do not grow much, and anyone who dares to climb the mountain has been hit hard by the red troops on both sides of the mountain.

In just three minutes, there were no less than 100 devils who were killed on the way to counterattack.

Perhaps Ikeda's military orders also worked, and instead of blindly counterattacking upwards, the Japanese invaders organized themselves in squads and squadrons to frantically build positions, and the grenadiers carried by the troops also continued to fire grenades at the firing points on the mountains to cover their infantry.

The Japanese grenadiers are the best front-line support weapons designed by the Japanese during World War II, especially the Japanese grenadiers are almost always the most cunning veterans, and from the very beginning of the battle, they hid. Don't look at the terrifying power of the explosives flying in the sky, the Japanese army suffered a lot of casualties, but the casualties of the veterans were not too large, and most of the Japanese soldiers who were killed or shot were new recruits, especially the second-line soldiers of the baggage wing squadron who rarely had the opportunity to go to the battlefield.

Dozens of grenadiers and the smoke of explosives were sneaking up the hill, causing some casualties to the attacking troops, and two heavy machine gun squads were attacked by the grenadiers because they were too engaged, and not only the team members were either killed or seriously injured, but even the heavy machine guns were damaged.

This made the two infantry regiment commanders extremely angry, and they invariably sent the elite shooters from their respective infantry battalions to carry out key strikes on the Japanese grenadiers on the battlefield, not to mention the fact that they also took out their own belongings ---- mortars to chase the discovered Japanese grenadiers.

That's right, don't look at the tinkling of the poor red troops, each soldier only fires twenty rounds of ammunition in a battle, but there are still mortars. Not to mention that Liu Lang sent a batch of mortars in Hadapu, that is, the red troops themselves, when they set out from Jiangxi, they were reluctant to throw away the mountain artillery that had been emptied of the shells, and they forcibly crossed 25,000 miles with hundreds of kilograms of the thing on their shoulders, and you know how much importance the red soldiers attached to artillery.

This mortar, each infantry regiment of the red army has as few as two and as many as four, which is much stronger than the Sichuan army that went out of Sichuan to resist Japan in the old sleeve wearing straw sandals, straw hats, carrying bolts, and tied with hemp rope in time and space.

Fighting with mortars and grenadiers is naturally much cheaper, and the two weapons are not at the same level at all. That is, the Japanese army had more grenadiers.

In fact, the number of Japanese grenadiers in the valley was actually quite pitiful compared to their numbers.

Surrounded by the valley were two squadrons of infantry and four squadrons of baggage wings, numbering as much as 2,500 men. According to the normal equipment of the Japanese army, there are nearly 200 people in one infantry squadron and three infantry squadrons, and according to an average of 2 grenadiers per squad and 6 grenadiers in one infantry squadron, then the Japanese army with a strength of up to 2,500 people will have at least 60 grenadiers.

However, the squadron of the baggage wing is just a supplement to the regular infantry of the Japanese army, and the most important job in peacetime is to carry materials, and their equipment can not be compared with the regular infantry squadron, although the number is as high as more than 500 people, but it is still divided into three squads, and the number of each squad is three times that of a regular infantry squad.

To put it bluntly, the four squadrons of the baggage wing numbered more than 2,000 people, almost close to two infantry brigades or an infantry regiment in China, but they were 24 light machine guns and 24 grenadiers, no heavy machine guns, no infantry artillery, they were pure light infantry.

The equipment of the Continental Army, which was coaxed by the Imperial Japanese Army, was not reflected in them at all. Not to mention encountering an ordinary Chinese infantry regiment, they can't occupy much advantage, if they encounter the bald boss who has spent a lot of effort to equip the German armor infantry regiment, they can be hung and beaten into a Xiang.

The Japanese troops in the valley were only equipped with 36 light machine guns and 36 grenadiers, and the most powerful ones were probably the 12 heavy machine guns of the heavy machine gun squadron and the two infantry guns.

If you just look at it, it's not bad, such equipment is enough to hang an ordinary Chinese infantry regiment, even better than the infantry divisions of some local warlords. However, they faced a condescending blow from the two infantry regiments, the most elite of the Red Army, which were supplemented with a lot of guns, and moreover, on a position of 3,000 meters long.

On average, more than 80 meters, a light machine gun and grenadier will be allocated, and an average of 250 meters, there will be a heavy machine gun, such a density of firepower is really too sparse.

What's more, under the leadership of Ryo Ikeda, a squadron of 700 men from an infantry squadron and a squadron of baggage wings were desperately rushing towards the road from which they came, trying to hold the rear road. The firepower of the 1800 centaurs left in the valley is even more ridiculously low.

Fortunately, it is not the independent regiment that is participating in the battle now, otherwise, with their crazy firepower output of mortar and "Hitler chainsaw" reinforced to the infantry platoon, they would not immediately beat the Japanese army, which is mainly the second-line soldiers of the baggage wing, immediately doubt life?

After the Japanese army's frantic counterattack achieved certain results, it immediately suffered a retaliatory blow.

Not only did the two commanders of the infantry regiment angrily move out of their own regimental treasures, but they used the few mortar shells to hit the grenadiers that caused many casualties on their own side.

As the commander-in-chief of the front line, Liu Lang, who had observed the battle situation at close range, quickly ordered the 80 flying thunder cannons that had already been exhausted to have a base of five explosive packs to stop firing, and each cannon left two explosive packs for final reuse.

After several minutes of throwing explosives, the expected effect had basically been achieved, and although it was impossible to replicate the miracle of the Qigancun Gorge that destroyed more than 2,000 Japanese soldiers in one explosion, the Japanese army suffered at least three or four hundred casualties.

Originally, the role of flying thunder artillery in this kind of ambush battlefield was to "surprise and attack the unprepared" and take advantage of the characteristics of such weapons that the enemy was not familiar with before, to kill and injure a large number of living forces, but we cannot expect the opponent to be stupid all the time. The opponent is not stupid, although the aura of being called the first army in Asia is a bit ridiculous, but people really have not encountered any opponents in Asia, except for eight years in China.

However, how many casualties has China paid for this? That's almost eight years filled with human lives.

The Japanese troops who had basically judged the approximate range of the flying thunder cannon were all hiding outside the explosion range of the explosives thrown by the flying thunder cannon, and if they continued to fight, they would only create a little more gunpowder smoke to cover for the little devils.

As a result, the flying thunder artillery, which relied on great power and great luck to kill and kill, stopped shelling, and the artillery battalion officially debuted.

The artillery observation group, which had already been on the ridge, quickly sent to the artillery battalion the positions they had observed the Japanese troops were building, especially the positions of the heavy machine gun fire points, in the language of flags.

The river valley is wide, and for the Japanese troops who were ambushed by pure infantry, it was not as miserable as the 40th Infantry Brigade in the previous Qiqian Village, but there was still some room for survival, and they could even build field positions according to the terrain in the fields in the river valley to resist stubbornly.

Just like in the Battle of Pingxingguan, because the 115th Division only had a small number of mortars, the two squadrons of the baggage wing that were ambushed resisted for hours in front of opponents who were several times their size.

However, this terrain is simply the coolest position for the artillery battalion that has moved the mountain artillery up the mountain, and there is no one.

They didn't have to worry about accidentally hitting friendly troops on the hills on both sides, they just needed to aim at the Japanese positions at the bottom of the valley and open fire.

The mortar position with a range of 2,500 meters was built in the middle of the valley only 700 meters, and the four 41 mountain guns with a range of 6,000 meters were located on the Cangyan Peak, completely covering all positions in the valley and there were almost no dead ends.

When the familiar sound of mountain cannon guns ejecting their chambers sounded, Ryo Ikeda, who was rushing towards the place where he had imagined himself to come from, was first overjoyed, and then his face turned as pale as a dead man's face when he saw the fire flickering in the river valley in the distance.
