Before Qi Hongying's reinforcements arrived, even if Stilwell had a good way to deal with it, he was unable to implement it due to the limited number of troops.

But now it's different, although the arrival of reinforcements can't achieve the effect of turning the tables, some tactics can be implemented, and if you're lucky, you may not be able to hold out for three or five days.

"So you want the instructor to go to defend the capital peak." Qi Hongying almost understood what the other party meant.

"You can't go all of them, at most four regiments (more than 6,200 people), in case the Russian-Manchurian coalition forces abandon that area, the Juyong Pass side may not be able to withstand it." Stilwell said.

Although there were reinforcements, they were not large enough for Stilwell to squander.

"Don't worry, I only need three regiments (more than 4,200 people) to be enough, and I guarantee to contain at least 20,000 enemy troops!" Qi Hongying swore an oath.

Maybe the first division needs four regiments, but the instructor is well-equipped and the combat effectiveness is stronger, Qi Hongying is confident that he only needs three regiments, and he will definitely be able to hold the military capital peak for at least three days.

What's more, in this rescue of Juyongguan, the instructor also brought three weapons of mass destruction from the Weapons Research Institute..........

The battle in front of Juyong Pass has not been temporarily suspended because of the arrival of the instructor, and even the Russian-Manchurian coalition forces have not found any trace of the instructor until now.

As time went on, the sky darkened, and as night fell, the frequency of the Russian-Manchurian offensive did not decrease, but became more violent.

The Russian-Manchurian alliance is to use this kind of non-stop attack to exhaust the defenders in the city, if Stilwell has no reinforcements, or only 5,000 defenders of the capital have arrived, it really can't hold out for long.

It's a pity that what arrived this time was Qi Hongying's instructor, an army that was only stronger than the first division in terms of equipment and soldiers' military quality.

Zhang Xiaopeng was originally a weapons tester at the lowest level of the Beijing Weapons Research Institute, but when he signed a five-year employment contract and a lifelong confidentiality agreement with the Weapons Research Institute, he was doomed to obscurity for the rest of his life.

Although the Weapons Research Institute does not strictly restrict the personal freedom of these staff members, due to the provisions of the confidentiality agreement, except for the free movement of these staff members in Majiazhuang, any plans to go out must be reported to the department head in advance.

Zhang Xiaopeng's ancestral home is Taizhou, a few years ago, the natural disaster **, his family was ruined, he was alone, he entered the weapons research institute for two years and three months, usually in addition to work, can only stay in the dormitory to drink and chat with colleagues.

It can be said that today is the first time Zhang Xiaopeng has walked out of Majiazhuang, and of course, this is also the first time he has joined the battlefield.

"Master Zhang, no matter what situation you encounter later, don't panic, just follow us, we will try our best to ensure your safety!" A soldier with the rank of second lieutenant said to Zhang Xiaopeng.

The battlefield is changing rapidly, and this second lieutenant does not dare to guarantee the safety of the other party 100%, but it is not difficult to see from the establishment of the national defense force that Zhang Xiaopeng's treatment is at least the treatment of a regimental-level officer by sending a platoon to protect it.

The first time he entered the battlefield, Zhang Xiaopeng's whole person was blindfolded, and he didn't hear the second lieutenant's words clearly.

"Boom!"

A cannonball hit the city gate not far ahead, and the huge impact force made the ground dozens of meters away from the city gate tremble slightly.

"The 12-pound (5.4 kg) Hongyi cannon, solid bullets, the maximum range is 2,100 meters, the killing range is 10*10 (10 meters in a radius), and the power is ...........weak," Zhang Xiaopeng involuntarily reported the data after the shell landed just now.

As a weapons experimenter, this is a basic skill that he has mastered in two years, and in today's highly tense atmosphere, he can't help but say it to relieve the tension in his heart.

At this moment, the gate of Juyong Pass was finally opened, and a fierce shout of killing came from the front team, and the instructor took the initiative to launch a counterattack against the Russian-Manchurian coalition forces outside the pass.

At the same time, the Ming army concentrated all its artillery and launched a fierce counterattack towards an artillery concentration area of the Russian-Manchurian coalition army outside the city.

The sound of shouting and killing and explosions was endless, Zhang Xiaopeng's spirit was getting more and more nervous, and his mouth was even more involuntarily, saying some puzzling weapon data, and even how to leave Juyong Pass, he didn't know himself.

Zhang Xiaopeng's team is the second echelon of this raid, this echelon currently has no combat mission, basically every soldier, carrying a large number of weapons and ammunition, followed the first echelon of soldiers responsible for opening the way.

Due to the sudden large-scale counteroffensive of the Ming army, and it took the initiative to go out of the city to fight, it directly caught the Russian-Manchurian coalition army by surprise.

The battle between the two sides lasted for a whole day, and although the Russian-Manchurian coalition forces attacked in turns, it was much easier than the Ming army on the city tower, but the numb attack all day long, and the reaction ability was still reduced.

Especially after the Ming army took the initiative to launch a counteroffensive, many generals of the Russian-Manchurian coalition army, thinking that a large number of the Ming army had arrived, instinctively began to search the battle line, observe the follow-up movements of the Ming army, and did not dare to confront the other side at all.

Fighters are often fleeting, because of the hesitation of the Russian-Manchurian coalition forces, resulting in the emptiness of the front-line troops, and soon the instructor rushed through a gap, and successfully took the military capital peak outside the pass..........

"Hurry up, hurry up, hurry up and set up defenses, the first battalion will continue to bite the enemy and not give the other side a chance to breathe, and the second battalion and the third battalion will dig trenches on the spot and build firepower points!" Li Runshu, the head of the second regiment of the instructor, said loudly.

They did take the Jundu Peak, but the height of the entire peak is less than 100 meters, and the terrain is gentle, once the Russian-Manchurian coalition forces react, mobilize heavy troops to encircle and suppress, and there are no fortifications, the three regiments of the instructor want to withstand the attack of the other party, it is still very difficult.

Therefore, we must take advantage of the fact that the other side does not know the reality and does not dare to attack rashly, and quickly build several simple lines of defense.

There are two regiments in the first echelon, one of which is Li Runshu's second regiment, not long after they took Jundu Peak, the fourth regiment where Zhang Xiaopeng, the second echelon, was located, also arrived smoothly and began to assist the second regiment and the third regiment to build a defensive line.

As night fell, the Ming army launched a sudden attack, and for a while, the Russian-Manchurian coalition army could not figure out the pulse of the Ming army, so they could only retreat ten miles back and put up a defensive formation, trying to find out what the Ming army was smoking.

It's a pity that the battle came and went quickly, only an hour passed, the Ming army's attack came to an abrupt end, and the army out of the city did not return to Juyong Pass again, but directly occupied the military capital peak and began to build a defensive front..........

Zhang Xiaopeng was in the trenches at the forefront of Jundu Peak at the moment.

The area where he was located was only 300 meters away from the roadside, surrounded by a natural fortress formed by a huge rock, and more than 10 meters in front of him, there was a ravine more than 10 meters deep.

Set up a firepower point here, except for the Russian-Manchurian coalition army from the left slope, the enemy is basically unable to directly reach here, it can be said that as long as a battalion on the flank is not exhausted, Zhang Xiaopeng's position, there will definitely be no enemy can step into this position.

"Master Zhang, what the hell is this? The gun is not like a gun, the gun is not like a gun, why is our division commander so precious to this thing? A little soldier who was in charge of helping couldn't help but ask.

"This is the Thunderbolt machine gun, the latest burst weapon developed by the Weapons Research Institute, with a long range and great power, with these three machine guns, no matter how many enemies come, they don't want to break through from here!" Zhang Xiaopeng said confidently.

That's right, Qi Hongying got it from the Weapons Research Institute, and the big killing weapon that is really in the experimental stage is a heavy machine gun.

And it's a manual, multi-barreled machine gun similar to the Gatling.

Due to the partial similarity with the Thunderbolt developed by the Ming Army before, the personnel of the research institute called this weapon the "Thunderbolt Machine Gun" before the official thing was named.

The automatic principle of the Thunderbolt machine gun is not much different from the principle of revolver firing, which uses a set of transmission mechanisms to rotate several barrels around a common axis, so as to complete continuous shooting.

The Thunderbolt machine gun has a separate steel chamber (the chamber is separated from the barrel), its tail section is closed and equipped with a ramming cap.

The shooter rotates the barrels, which are evenly arranged along the circumference, by shaking the crank, and the chambers filled with ammunition enter the latching slots behind each barrel from the feed hopper. When the barrel is turned to a certain position, the firing pin fires the ammunition.

And when the barrel is turned to another position, the chamber after the shot is withdrawn from the machine gun, and the work of automatic exit of the cartridge case is completed.

The chamber can be reused, and the barrel rotation can complete the loading, firing and unloading of 5 rounds (five-barrel machine gun) ammunition, reaching a rate of fire of 200 rounds per minute, but there are disadvantages such as gunpowder gas leakage.

In order to solve this problem, the developers used a separate metal cartridge ammunition that had only been developed recently, thus eliminating the paper cartridge ammunition used in the "single pistol".

The Thunderbolt machine gun is mechanical, requiring a human hand to turn the shaker to shoot, and someone must be on the side to load the gun to prevent jamming.

A Thunderbolt machine gun requires at least three professionals to operate, and soldiers who have not been exposed to this kind of firearms really can't get started in a short period of time, Qi Hongying can only take the risk and let these weapon testers who have never been on the battlefield come to handle it personally.

Although the Thunderbolt machine gun is still in the experimental stage, it has also reached the final commissioning threshold, and in order to test its sustained combat capability, the weapons research institute has prepared more than 30,000 rounds of ammunition, which this time were transported to the front line along with three heavy machine guns.

Although it is not clear that the average service life of this firearm, after preliminary experiments, Zhang Xiaopeng and others have a general understanding of data such as rate of fire and range.

The Thunderbolt machine gun is a five-barreled machine gun, with a total weight of about 78 kg, a caliber of 14.7 mm, a maximum rate of fire of 200 rounds per minute, and a maximum effective range of 600 meters after using smokeless gunpowder.

Not to mention anything else, with a rate of fire of 200 rounds per minute and an effective range of 600 meters, three Thunderbolt machine guns blocking the intersection at the foot of the mountain are definitely more than enough.

This is also one of the confidence of Qi Hongying to dare to face 100,000 Russian-Manchurian coalition troops alone with 4,600 people.

The other strength is 36 80-mm mortars with a range of up to 1,200 meters.

Mortars have been invented as early as during the Northern Expedition, but their manufacturing technology and cost have been very high (mainly the cost of shell manufacturing), and after the reunification of the Ming Dynasty, the fortress trenches faced by the face are much less, and in the field, the mortars with a range that is not outstanding are greatly reduced.

However, the newly developed 75-mm light rapid-fire gun is more favored by the Ministry of Defense in terms of cost performance and output.

Therefore, after 300 mortars were manufactured to meet the needs of the Air Force and special forces, production was temporarily discontinued.

After all, mortars, a siege weapon, did more harm than good to the Ming army, which mainly relied on the defense of the city, and no one wanted the mortar's technology to leak out and let the enemy use it to bombard their own cities.

It can even be said that thanks to the Ming army in Mongolia, no mortars were used, if the Russian-Manchurian coalition army captured more than ten mortars through the battle and put them into this siege battle, then it is really difficult to predict whether Juyong Pass is still in the hands of the Ming army.

Of course, mortars are not only suitable for siege warfare, but also because of their high rate of fire, they are ideal for suppressing enemy infantry.

As the most equipped unit in the whole army, the instructor is also equipped with mortars, and this time Qi Hongying delivered all 36 mortars to the three regiments of the defending army Dufeng for centralized use............

In the face of the sudden attack of the Ming army, the Russian-Manchurian coalition army was in great confusion in a short period of time, and if the Ming army took the opportunity to launch a full-scale counteroffensive, the Russian-Manchurian coalition army might even suffer a major defeat.

If the reinforcements from Zhangjiakou could arrive at this time, maybe Stilwell would really dare to give it a go, but unfortunately, the Ming army had too few troops, so he could only "bluff" and close the city gate again, waiting for the next move of the Russian-Manchurian coalition army.

After this counterattack, the two sides unanimously ceasefired, and the Russian-Manchurian coalition army needed to find out the true intentions of the Ming army, and the Ming army hoped that such a ceasefire would last as long as possible.

After about an hour of exploration, the Russian-Manchurian forces finally figured out the intentions of the Ming army.

"As I expected, this should be the reinforcements of the Ming army, listening to the report of the soldiers in front, the number is about five thousand, which is not much different from the defenders of the capital as originally envisaged." Han Dai said.

"Please make it clear, the report from the front line says that the other party's army out of the city this time is nearly 5,000, is the Ming army a fool and does not leave a trace of reserves? And you also saw the battle just now, in just one hour, there were 20,000 troops in front, and they were easily dispersed by the other side, do you think this will be the combat effectiveness of a garrison? Tsarist general Yerumov questioned loudly.

"It's ........ Since it is the capital of the Ming Dynasty, there must be a lot of weapons in reserve, and it is normal for these people to have more sophisticated equipment and improve their combat effectiveness. As for the reserves, it must also be a conspiracy of the Ming army, deliberately bluffing. Otherwise, if the opponent's forces were sufficient, they should have continued to attack in one go, and would not have stopped just after taking Jundu Peak. Han Dai argued.

Although even he himself did not believe in this reason, there was no better explanation.

Could it be that his intelligence is wrong, and the Ming army really has more troops stationed in the capital?
