The Japanese cavalry fell short and automatically gave up the attack on the three dogs and scattered, but at this time the three battalions would not let them go.

It is unlikely that the infantry company wants to pursue the cavalry troops, but if it is arranged from the beginning and most of the Japanese cavalry squadron is eliminated, it is still possible to face the scattered cavalry.

The Seventh Company of Wutouling, the Eighth Company of Wugongling, and even the Ninth Company all dispatched some soldiers at this time according to the order of the battalion headquarters and set up ambush points represented by the squad at various key points.

Each group was equipped with a squad machine gun, and the group was connected and protected from each other, using the high ground as a stronghold, not to confront the Japanese cavalry head-on, but only to block the attack and consume the enemy one by one.

In this way, the remaining dozens of cavalry squadrons of the Japanese cavalry were scattered in the small villages of Xia Yu and Shang Yu, and because the target was relatively large in the field, they were afraid of being shot by the Chinese army, so they had to hide in the village houses.

At this time, when the Japanese cavalry attacked the hill where the headquarters of the third battalion was located, they thought that they would succeed soon, so they fired signal flares.

That is, a signal to the main force of the Japanese army on the side of Gray Port, the main force of the Japanese army on the side of Gray Port is ready to go, and is waiting for news from the cavalry.

As soon as the cavalry team succeeded, they immediately launched an attack, and the inside and outside should be combined to flank the first line of defense of the Chinese army.

Therefore, as soon as this signal flare was fired, the Japanese troops in Gray Port Town immediately fired their artillery in unison, and a large amount of steel and gunpowder were poured on the positions of the three battalions of Shaguling, Wutouling, and Wugongling.

The positions of the Ninth Company from Shaguling to Wutouling and the Seventh Company from Wutouling to Wugongling suffered the most serious blows, but fortunately, these two companies, with the help of Shanggao villagers, built a large number of bunkers and hiding caves, and the relative losses would be a little less.

However, the Japanese artillery fire in the position of the Eighth Company was not much, maybe this side was more detoured, and the Japanese army wanted to pass through here to Shanggao, or a big road under the Headless Ridge was the only way to go.

Although the area near the river of the Eighth Company is relatively empty, there is no main road, and the Japanese army's artillery, ammunition and materials need to be transported by the main road to reach the front line.

Ammunition and materials are the blood of an army, and the main transportation route is the blood vessels, without the smooth flow of blood vessels, the blood input cannot keep up, and the front line will soon run out of ammunition and food, and it will not be able to fight.

Therefore, the Japanese army's conical tactics, using superior forces to quickly advance the assault, are to attack along the main road, otherwise it will be the same as the 106th Division in Wanjialing.

For small guerrillas in a small unit, it is possible to try several times, but if it is a large unit, it is very dangerous, and it is very difficult for a unit at the battalion level to maintain a long-term operation without the support of logistical support.

Therefore, it is understandable that the attack of the main force of the Japanese army directly stared at the headless ridge to fight, and now the Japanese army received a signal from the cavalry team and immediately carried out wanton and indiscriminate bombardment of the Chinese army's position at this point.

Although it is said that the main road from Shanggao to Gao'an was destroyed by the villagers into paddy fields, the Japanese army's engineering units were still very powerful, and within a few days, a road was paved to come out.

The Japanese air force was also very supportive, constantly escorting the engineering troops, and as long as the artillery of the Chinese army artillery unit came to blow up the newly repaired road, the planes would immediately follow.

The artillery units of the Chinese army were so chased that they did not dare to show their faces later, so they could only rely on some guerrillas to sneak attack the newly built roads of the Japanese army and blow them up with explosives.

However, the effect was mediocre, as the Japanese engineering units were able to repair it quickly, and they collected a large number of door planks and used light chariots with tracks to advance and pave the road at a very fast speed.

Therefore, the Japanese artillery was able to slowly keep up with the main attacking force, but it was the Japanese army that made sufficient preparations for the Chinese army in the few days when the road was being built.

For example, the excavation of the fortifications of the third battalion this time can have enough time to prepare, otherwise, it will be too late to build so many fortifications, and you can only use the temporary terrain to fight the Japanese army.

When the Japanese artillery passed, its infantry and vehicle coordinated attack formation appeared again, which was the old three of the Japanese attack, aircraft artillery, followed by infantry coordination, and finally cavalry pursuit.

If you deal with the general Chinese army, these three axes are down, and not many troops can withstand it, but now it is different, it is the 74th Army, the elite of the Central Army.

The 3rd Battalion, which had been fighting with the Japanese army for many years, was naturally very familiar with this set of things of the Japanese army, and there were many ways to deal with it, mainly by using terrain and bunkers to eliminate the power of Japanese artillery shells.

Next, in the face of the Japanese tank and combat vehicles, it is much easier to do now, in the past, human bombs were needed to blow up, but now the regimental machine gun company is equipped with 37 tank defense guns.

This gun is simply the nemesis of the Japanese light tanks and combat vehicles, it is small, the barrel is less than two meters, the width of the gun is more than one meter and six points, the height of the gun is only a little more than one meter, and the marching weight is only 450 kilograms.

Therefore, the maneuverability is very good, even without a tractor, 4 soldiers can push it around, and this direct advantage is that it can hide in bunkers, and it can also be pushed and run to avoid planes and multiple points to hit Japanese tanks.

When dealing with tanks, the 37 anti-aircraft gun mainly fires 37 mm cap-piercing shells, which can penetrate 34 mm thick homogeneous steel armor at a distance of 100 meters, and has an armor-piercing capacity of 29 mm at a distance of 500 meters.

The Japanese Army's 97 medium tank, which is now the thickest armored, is only 25 mm, while the armor thickness of the Japanese Type 89 medium tank, which is common on the Chinese battlefield, is only 17 mm.

The larger number of Type 94 and Type 95 light tanks had armor thickness of only 6-12 mm, and the armor plates of Japanese tanks were basically riveted instead of welded.

In the Battle of Songhu that year, the 37 anti-aircraft guns were able to tear through the thin skin armor of the Japanese Type 89 medium tanks from a distance of 500 meters, which made the Japanese army feel very dangerous.

There were seven or eight Japanese tanks that did not dare to attack a 37-millimeter anti-aircraft gun of the Chinese army, and some even fled in panic.

Due to several years of combat attrition, the 37th anti-aircraft artillery of the Chinese army was not only constantly pursued and killed by Japanese aircraft, but also was also studied by the Japanese infantry to find a weak underbelly.

That is, the effective firing range of 37 is too short, just about 500 meters, such a short distance, it is more than enough to deal with combat vehicles and tanks, but in the face of enemy infantry artillery mortars, it will be troublesome.

This is still the weapon of the Japanese infantry unit, if it rises to the artillery and air force, the battle defense artillery can only wait to be destroyed, or quickly slip away, if it can slip away.

Now, in order to take care of the three battalions that bear the brunt of the first position, the 152nd Regiment has transferred the only 37th combat anti-aircraft gun gun of the regiment's machine gun company to the third battalion.

Sangou treated this cannon as a treasure and gave it to the hands of Wu Dingli, the commander of the seventh company, although the commander of Wu Company had not been in office for a long time, but he was also the true biography of the old company commander of the seventh company, Sangou and Xiucai.

The Seventh Company can attack and defend well, and in terms of defense, it is mainly very capable of digging fortifications, renovating tricks, and being practical and simple.

As for how to protect the 37th anti-aircraft artillery, Company Commander Wu and the soldiers below discussed several sets of plans to dig out a few positions and bunkers that hide the 37th artillery, and even the line was planned, and there were special tracks for moving forward and retreating.
