Chapter 1631 The Wind Rises in the South

In the conference room of the Institute of Electromagnetism, Laizhou, An Yi was listening attentively to Ding Molan's explanation of the experimental footage taken by the camera. Pen fun and pavilion www.biquge.info

In the afternoon experiment, Tesla used his supercoil to drive a payload of 10 kilograms on a 50-meter track to conduct a full-output test, but the test was interrupted because the shock wave of the payload broke through the sound barrier on the track, shaking the track.

Sound barrier refers to the fact that when the speed of a flying object is close to the speed of sound, it will catch up with the sound waves emitted by itself, and the result of the superposition and accumulation of sound waves will cause the generation of shock waves, which in turn will hinder the acceleration of the flying object.

After breaking through the sound barrier and entering supersonic speed, the front of the flying object will produce a cone-shaped sound cone, which will sound like an explosion to onlookers, so it is called a sonic boom or sonic boom. A strong sonic boom can cause damage not only to nearby buildings, but also to the parts of the flying object itself that extend beyond the impact surface.

Tesla's experiment, for the first time to verify the existence of the sound barrier, became the first person to confirm the sound barrier, from this point of view, this experiment was successful, especially rare, but also the use of the camera to capture the object when the sound barrier broke through, for the later research to provide valuable information.

After the experiment, Tesla couldn't wait to summarize and try to improve the payload and orbit, so Ding Molan, who served as the assistant of the experiment, explained the importance of the experiment to An Yi instead of Tesla.

Although An Yi also felt that this experiment was great, he still couldn't help but whisper: "Mo Lan, is there any hope that Uncle Nikolai's experiment will be useful in military technology?" ”

Ding Molan nodded affirmatively: "Of course, once this electromagnetic projection track is successfully developed, the first benefit is the research on supersonic aircraft, through this projection track, the aircraft model can be hit to double sonic speed, hypersonic speed and even extreme supersonic speed, which will be a useful supplement to the supersonic wind tunnel we are building."

In addition, this projection rail can also be used on aircraft carriers being designed, think of relying on electromagnetic catapult to send fighters into the air, so that the fighters accelerate evenly and the force is controllable, which reduces the probability of many accidents for pilots. And for the designers and naval operators of the aircraft carrier, it is a big boon, which can reduce the occupied area of the hangar deck to a third of the original area, and the weight is also significantly reduced. There are many other uses that I haven't thought of yet......"

"That's enough!"

An Yi was greatly satisfied, seeing that the time was not early, he stepped forward to hug Ding Molan's waist and said gently: "Molan, there is nothing else to do today, right?" Eat together and finish ......"

As soon as he said this, the door of the room rang inappropriately.

An Yi hurriedly let go of Ding Molan, turned his head and shouted, "The door is not locked, come in!" ”

Shen Fengdao hurriedly entered and strode to An Yi's side: "There is movement over there in Siam, according to the information detected by the intelligence department, it will be very dangerous today and tomorrow!" ”

An Yi smiled apologetically at Ding Molan, and then said to Shen Fengdao: "Old Shen, you go outside first to prepare the vehicle, I have something to say to Molan!" ”

Shen Fengdao nodded to Ding Molan and turned to leave.

An Yi held Ding Molan's hand, his face full of regret: "I'm sorry, Molan, originally I wanted to take advantage of this opportunity to accompany you well, but the Siamese people didn't give me this opportunity, I ......"

Ding Molan raised her head, stretched out her hand to cover An Yi's mouth, and looked at An Yi affectionately: "I'm fine, everything is based on the overall situation." Now Nanhua is at a critical juncture, and the slightest carelessness may lead to the deterioration of the situation. ”

An Yi gently kissed Ding Molan on the forehead and strode away.

......

At nine o'clock in the night, on the Siam side of the national border, in Aran, Kachun, Phibun, Mudahan, Tabo and other places, artillery fired in unison, and countless bombs were poured on the land of Nanhua on the other side of the border.

After an hour of suppression, the invasion of the Siamese Army officially began.

The Siamese, with the help of instructors sent by Japan, armed a total of thirty divisions. In this attack on Nanhua, the 1st to 5th Divisions attacked Bobe and other places in the Tonle Sap Plain of Tiannan Province, Nanhua, and the goal of the first stage was to occupy the town of Shisophong, the county seat of Mianji County; The 6th to 10th Divisions attacked Osma, Gonggelie and other places, and the goal of the first stage was to capture Sanlong Town, the county seat of Sanlong County; The 11th to 12th Divisions attacked Mong Kau with the objective of capturing Pakse City on the right bank of the Mekong River and holding it; The 13th Division attacked Savannakhet and the 14th Division attacked Vientiane, and these two armies were feints to contain the southern transfer of troops from the north of the Anjia Army.

The Siamese Army used five divisions as territorial defenders and eleven divisions as strategic reserves, concentrating superior forces to attack the defense-empty southern plains of South China, hoping to take advantage of the chaos to first solve the Tonle Sap Plain in the lower reaches of the Mekong River, advance the battle line to the Mekong River, and threaten the security of Saigon.

"Porphyr—"

The continuous firing put a lot of recoil on the machine gunner's shoulders. In the sound of tearing cloth, the body of the general-purpose machine gun and the body of the machine gunner were shaking rhythmically, and the obtuse angles of the foot bracket at the front of the machine gun were rubbing back and forth, leaving two obvious scratches on the rock base of the trench, and the bullet casings that jumped out of the chamber of the gun, like beads with broken threads, fell in strings into the trenches.

With one of the cartridge belts completely eaten by the machine gun, the Heavy could already feel the heat of the barrel, and he quickly dragged the machine gun off the position, and the co-gunner, wearing thick gloves, immediately replaced the barrel that was about to deform. For a well-trained machine gunner, this process takes only fifteen seconds, plus half a minute to reload the new cartridge belt, and this universal machine gun can be rejuvenated.

When the general-purpose machine gun returned to the battlefield, the Siamese infantry was still rushing forward and charging towards the Enjia army's entrenched positions.

This is the town of Pobi, a small village of just over 1,000 people, on the border between South China and Siam, and the townspeople were evacuated when the shelling began. The three-line trench to the west of the town was a strong guarantee for the An Jia's army to resist the Siamese invasion.

On the border between South China and Siam, there are not many roads that can be easily accessed by the army, and the town of Pobe is located on this main transportation artery, and its geographical location is extremely important.

However, in order to tempt the Siamese army to invade, Gu Changfeng only arranged one battalion of troops here, and the Siamese army, which took the initiative to attack, had an absolute advantage in numbers and rushed to the front of the position.

Flares rose into the sky one by one, and in the sound of machine gun fire, the snipers assigned to each squad quickly shot at the key figures in the attack group, first those officers who had learned from the Japanese who rushed forward with command knives, and then the Siamese machine gunners and grenadiers, one by one, hateful fellows, spewing blinding bloody arrows above their heads, fell to the ground one after another.

The infantry of the An Jia Army lay on their stomachs on the trenches, and the bullets fired from their semi-automatic rifles flew out like a whirlwind, knocking down the Siamese soldiers who were rushing forward in front of the position. During the attack, many of the Siamese infantry lay down and fired, but their marksmanship was very poor, and even ten shots might not be able to hit a single shot.

However, there were so many Siamese that the Siamese infantry at the forefront had reached less than thirty meters from the first trench under the charge of the first one. Suddenly, an overwhelming array of grenades flew out of the trenches of the An Jiajun army and smashed down on the locust-like crowd of Siamese troops.

Grenades fell into the crowd, exploding fireballs, countless steel shards flew in all directions, and with a violent explosion, the Siamese soldiers let out terrifying screams and fell to the ground.

However, the numerical superiority was still playing a major role, although the grenade temporarily exploded a fault more than 30 meters wide, but it was instantly filled up by the Siamese army that pounced on the back, and advanced another 10 meters to the position, and the officers and soldiers of Anjia on the position seemed to be faintly hearing the breathing sound of the opponent.

At this time, the An Jiajun began to use mortars to conduct blocking fire.

"Bang-"

After the sound of a platoon of mortars, the shells flew into the sky in patches to reach the highest point, and the shells smashed down into the dense crowd of Siamese troops with a piercing whistle.

"Boom-"

A series of explosions rang out, and countless black and red fireballs rose from the ground, and sharp fragments flew through the air, cutting through the flesh and blood of the Siamese soldiers, some of whom were cut in two, some of whom had their heads cut off, some of whom had their limbs broken, and some of whom had been beaten into hornet's nests. The screams were incessant, and the Siamese soldiers on the ground were flying with blood.

At the same time, the snipers fired at the Siamese officers, machine gunners, and grenadiers who were cowering beyond the blast point, smashing monkey-like heads into rotten watermelons.

With the cooperation of mortars and snipers, the fighters in the trench once again threw locust-like grenades at the front of the position.

The grenades were overwhelming, and the Siamese soldiers who were in the trenches were blown to pieces, and the screams were repeated.

In a short period of time, the Siamese people have suffered more than 2,000 casualties, in this case, the Siamese officers who commanded the battle were ruthless, and the infantry guns, field artillery, and mountain artillery of various calibers poured dense bullets into the position of the Anjia army, and all kinds of fireballs of all sizes fell to the ground, raising countless fireballs of various sizes, violently exploding, and the tumbling flames merged into a dense wall of flames.

The Siamese soldiers, who were lying on the ground and crawling forward, suffered heavy casualties under the suppression of their own artillery fire, and the soldiers of the An Jia Army also suffered serious casualties. For a time, the mutilated corpses of soldiers on both sides lay on the trenches.

The bursting brains, the splattered blood, the mutilated bodies, the charred limbs, and the burning corpses made the soldiers on both sides feel sick, and the filthy and tumbling heat was filled with the pungent smell of gunsmoke, blood, and a vomiting stench.

The battalion commander of the guard in the rear town was stunned, and just wanted to give the order to put into the reserve, but the instructor Jiang Wentian stopped him: "Battalion commander, the task given to us by the division and regiment commander is to resist for an hour, and to give the Siamese army the illusion that our side is putting up heroic resistance." Now that we have repelled three enemy charges, and almost two hours have passed, we can retreat. ”

The battalion commander pointed to the outside of the town and shouted: "Old Jiang, look at it, our soldiers are bleeding and dying outside, but you call retreat, I, Zhang Meng, have not fought such a battle, if you want to retreat, I will take people up to ......"

"Comrade Zhang Meng!"

Jiang Wentian grabbed the battalion commander who was about to rush out of the command post: "What you should do now is not revenge, but to carry out the orders of your superiors." If we want to take the moral initiative in the international arena, we must put the Siamese people into the national border to fight! At present, the preparations for the group army and the front army have been completed, don't you know that if you insist on going your own way, you will ruin a big thing? The most important thing is that if you continue to do this, you will lead our battalion into a desperate situation! ”

Zhang Meng was drunk like this by Jiang Wentian, and his head suddenly sobered up.

With the introduction of the political commissar system in the troops, instructors have become de facto deputies, and in some cases, they can even replace erring commanders in command of troops.

"Okay!"

Zhang Meng finally chose to carry out the orders of his superiors.

Soon, the guard battalion withdrew from its positions one after another under the artillery bombardment of the Siamese army, quickly got on the trucks, motorcycles, armored vehicles that had been activated, and some of them rode horses, and quickly retreated.

After half an hour of suppressive fire, the Siamese attacked again, this time with great success, and rushed into the town of Pobi with little effort. Soon, the "great victory" of the "smooth" capture of the town of Pobpi, which was defended by a "large number of troops", was reported to the head of the Siam Army Central Cluster and the Ministry of Defense in Bangkok, causing a revelry.
