The battle at the pass has reached a fever pitch, the Mongolian army attacked wave after wave, and with the support of absolute superior artillery fire, the Mongolian army lined up in a skirmish line and jumped up in waves, attacking towards the defensive line.

The machine gun nests erected by the 706th Regiment were exposed to the fire of the Mongolian army, and soon, the Mongolian army was killed in front of them.

The officers and soldiers who followed had already prepared their bayonets, and as far as the eye could see, rows of steel helmets and bayonets were shining in the trenches.

The Mongol army had already rushed over, and this group of short and fat stump men had always been masters of the cold weapon era, and their ancestors had made a name for themselves with iron horses.

And today, they will practice the glory of their ancestors with blood and iron!

But on the other side of them, this group of men whom they called "southerners" were not afraid at all.

"When the two armies meet, the brave wins!" Huang Zhengzhong raised his saber and shouted, and the officers and soldiers behind him roared, and the officers and soldiers rushed out with rifles in their hands.

This is the most primitive form of warfare, two iron currents hit together, in this era of the 20th century, this mode of fighting solely relying on cold weapons has been rare, but it is the most able to reflect the will to fight a form of combat.

The bloody battle is still continuing, and at this moment the Hexi Valley has become a flesh and blood mill, and the troops of the Mongolian army are swarming here, rushing here from all directions, and the officers and soldiers of the 706th Regiment can only fight to kill the enemy.

At this moment, a roar sounded in the sky, followed by a blinding burst of fire not far in front of them, followed by the roar of machine guns.

"Air Force! Our Air Force is coming! The officers and soldiers of the 706th Regiment finally saw a glimmer of hope, and everyone seemed to have eaten *, and the vicious Mongolian army pounced.

Huang Zhengzhong held the bloodstained saber and looked ahead. A formation of several dive bombers was throwing all kinds of * into the dense formation of the Mongolian army, and the throwing * was not finished, when the planes swept by, the large-caliber cannons fired at the crowd on the ground, and the sound of the machine guns of the Tata Tower resounded loudly, and the positions of the Mongolian army were full of pieces of meat that had been blown to pieces.

"This battle is fought! Some of this battle has been fought! Huang Zhengzhong knew that the air force brought them not only supplies and damage to the enemy, but also a morale boost in despair.

What could be more exciting than seeing hope in the midst of despair?

"Brethren! Kill all the rebels! Huang Zhengzhong raised his arms again and shouted.

The officers and men of the 706th Regiment rushed forward like a flood.

Gunfire rumbled, and there was shouting of killing all around. Huang Zhengzhong also rushed forward with a saber, and a Mongolian soldier was slashed by him and his neck was cut, and the blood in the arteries soared dozens of centimeters.

Huang Zhengzhong was very happy to kill with a saber, Xiaohuzi was carrying an American-made * next to him to protect the whole process, and when he saw danger, he went up to a shuttle, basically ensuring Huang Zhengzhong's safety.

The troops became more and more courageous, and the Mongolian army was also red-eyed. The large-scale officers and soldiers gathered together, and there was no order or formation to speak of, and everywhere heard the sound of bayonets clashing and stabbing into the human body......

This bloody battle can no longer be seen with the eyes of right and wrong deployment, and the officers and soldiers on both sides have even forgotten why they are fighting, and there is only one thought at this time - to kill each other!

At this moment, a dense burst of gunfire rang out from the south. Huang Zhengzhong frowned, and secretly shouted that it was not good, could it be that the reinforcements of the Mongolian army were coming again?

Just as he was worried, several flares shot into the air, and in an instant, the dim battlefield was as bright as day. With the help of flares, he saw a group of officers and soldiers in khaki uniforms coming from the south, this new force was undoubtedly elite, in such a chaotic situation, they lined up in a basic skirmish line, the light machine gunners in front of them were evenly distributed, and the muzzles of the light machine guns spit flames, clearing the way for the troops behind.

"Mongolian army?" Huang Zhengzhong looked at it again, and saw a black flag waving in front of the team.

There is no doubt that this is the penal camp that made the Mongolian army look different!

"Reinforcements! Our reinforcements are coming! Many officers and soldiers raised their arms and shouted, and their voices passed like waves.

Among the Mongolian army, many people can understand Chinese, and many officers and soldiers have seen this black flag. Coupled with the fear of being attacked by airplanes just now, after encountering the enemy's frantic reinforcements, many people have lost the will to fight, and the pace of the offensive has slowed down.

"The punishment camp has arrived!" The officers and men of the penal battalion who rushed to the front shouted loudly. Their roars were accompanied by the sound of various gunfires.

The Mongolian army, which had previously occupied an advantageous position, suddenly lost its original advantage. The addition of thousands of officers and soldiers of the penal battalion made the scales of this war begin to tilt towards the side of the expeditionary force.

When the reinforcements from the penal battalion arrived, they joined forces with the 706th Regiment and began to fight back, and the Mongolian army began to show signs of defeat, and the attacking Mongolian army began to retreat.

They had now retreated beyond their original offensive lines, leaving nothing on the battlefield but nearly a hundred corpses.

The 706th Regiment began to repair on the spot, and at this time, the commander of the penal battalion came over.

The commander of the punishment battalion is a fat man with a black face who is not tall, and Huang Zhengzhong has never dealt with him, but I heard that this person has a bad temper.

Can you manage such a force, can you do it with a good temper?

After he walked over, the general's hat raised slightly and said: "I am from the penal battalion, our three battalions have now detoured from the left flank, now let's join forces and break through the pass of the Hexi Valley." ”

Huang Zhengzhong nodded, "That's the best." ”

He glanced at the saber in Huang Zhengzhong's hand and the blood stains on it again, and then glanced around, his face changed slightly, he patted Huang Zhengzhong's shoulder and said, "I'll listen to you!" ”

……

The combined penal battalion and the 706th Regiment attacked towards the Hexi Valley Pass of the Mongolian army. The defense line of the Mongol army was like a chicken and a dog in front of this iron stream, and the defeated Mongol army was quickly defeated, and the pass of the Hexi Valley was torn open, and the two armies in one place began to advance towards Kulen City.

……

At this time, the battle in the city of Cullen was still going on. General Batu commanded a large army to win a victory in a frontal battle with the Mongolian army, and the 2nd Expeditionary Army, under the suppression of strong firepower, surrounded the main tank units of the Mongolian army with sufficient mobility, and the anti-tank troops and tank troops together ate this group of enemies.

South of Kulen, under the pressure of strong firepower, the Mongol army began to retreat. The army pursued the victory, and by noon, the vanguard of the 2nd Expeditionary Army had entered the city of Kulen.

Batu and the generals walked out of the command post and drove towards the city of Kulen in a jeep, and along the way, there were discarded tanks and armored vehicles, some of which had been beaten and deformed, some of which were still burning, and thick smoke was rising...... Next to the destroyed tanks and armored vehicles were rows of prisoners. They were all dressed in military overcoats, with their belts and all their equipment, and they were squatting in rows on the side of the road, with their heads in their hands, guarded vigilantly by soldiers with steel guns.

Batu glanced at them and stopped looking at them, in his eyes these people were not complete evildoers, they were probably ordinary herdsmen like his own origins, but they were driven by this general trend.

"Did you get it?" Batu asked casually.

"No, Naganda and the Soviet advisers fled north after the defensive line collapsed. Troops have been sent to chase them, but they may not be able to catch up. Chen Xingguo seemed to have some regrets. He felt that if he could catch the Soviet advisers, he would be able to pull back the game diplomatically.

Batu disagreed, "If you catch it, you will come to a stalemate, and if you are diplomatically fooling, you will be swordsical and sanctimonious on the surface, but everyone knows the actual situation." Didn't Nanjing know that the Soviets supported the Khan? Doesn't Moscow know? Don't worry about these things anymore. ”

……

After two days of fierce fighting, the 2nd Expeditionary Army recaptured the city of Kulen, and at the same time, the 2nd Expeditionary Army took advantage of the victory and took back many important points around Kulen one after another.

This is not the point, the point is that the Khan and the group of independent people who relied on the survival of the army, the Mengzi army, were wiped out in this battle.

By the time the field troops of nearly three divisions stationed at Kulen retreated to the northern border, there were less than 1,000 men left, and not a single piece of heavy equipment such as tanks, artillery, and trucks had been lost.

At least for two years, they will not be able to launch a large-scale counterattack.

Batu's battle can be said to be a complete victory, but the 2nd Expeditionary Army also paid a lot of price. The Mongolian army was strong in combat and well-equipped, and in these battles, all units of the 2nd Expeditionary Army suffered serious losses.

Especially in the 706th Regiment, the casualties accounted for more than half of the total number, and even the regiment commander Huang Zhengzhong was wounded, which shows the fierceness of the battle. The other troops, even the penal battalion, which was extremely combat-ready, suffered a lot of damage, and the six battalions could only be fully formed in the battle.

But flesh and blood are exchanged for the integrity of the territory.

The Mongol army was defeated, and the independent forces of Mongolia no longer had anything to rely on. The next thing is Nanjing.

On the same day, the Ministry of Foreign Affairs of the Republic of China sent a note to the ambassador of the Soviet Embassy in Nanjing, through the People's Commissariat of Foreign Affairs of the Soviet Union, to lodge a solemn protest to Moscow over the discovery of a large number of Soviet-made weapons in the Mongolian army.

Conclusive evidence was in front of the Soviet ambassador, and he could not deny it.

An official of the Ministry of Foreign Affairs told the Soviet ambassador: "Your country is doing this in a clear violation of the covenant of the allies of the Cairo Declaration, and if this continues, we will consider dissolving the alliance with your country." ”

This did threaten the Soviet Union, because once the alliance was dissolved, it would mean the rupture of the anti-fascist front, which would be extremely unfavorable to the current counteroffensive of the Soviet army, after all, there were still millions of German tigers and wolves waiting for them in Europe.

On the same day, Stalin asked for a telephone conversation with Huang Ke, but the Nanjing side rejected the Soviet proposal on the grounds that it was "busy with affairs." Sun Ke, the premier, had a telephone conversation with Marshal Stalin, and the two only exchanged pleasantries and did not involve in-depth talks.
