Zhangjiakou, also known as Zhangyuan, Wucheng, known as the pearl outside the plug, the Great Wall of China winds through its territory, the grassland on the dam is endless, the grass is blue and the sky is beautiful.

However, such a beautiful place, since it was invaded by devils, has become increasingly depressed, slaughtered, humiliated, and oppressed, everywhere. The people are living in dire straits all the time.

However, today, the people in Wucheng City found that the devils and puppet army traitors in the city no longer had the laziness and arrogance of the past, and they were extremely nervous, as if they were facing a great enemy.

The people didn't know that the Dragon Tooth Column and other anti-Japanese troops of the Eighth Route Army were about to arrive, and the devils and puppet troops were about to come in a catastrophe, so of course they were very nervous.

Qiao Youhua led the northern offensive force consisting of four infantry regiments, one artillery regiment and two tank companies, and marched north from the same road.

Two days later, he rushed to the south of Zhangjiakou City, in these two days, Qiao Youhua led his troops all the way like a bamboo, successively recovering Yanggao, Tianzhen, Huai'an, Wanquan four counties, traveling more than 400 miles, everywhere he went, because there was no devil stationed, the local puppet army was invincible, and surrendered the city one after another, so the dragon tooth column almost did not fight much, and recovered the lost territory of hundreds of kilometers.

The topography of Zhangjiakou is high in the northwest and low in the southeast. The Yinshan Mountains go around the city from north to west, and the mountains are the world-famous Great Wall.

Therefore, the topography of Zhangjiakou is also to defend the north, not to defend the south, originally this is a border fortress town, without the steepness of the Yinshan Mountains and the winding Great Wall entrenched on it as a basis, in the face of the dragon tooth column from the south, it can almost be said that there is no danger to defend.

In this case, how can the Japanese puppet army stationed here not be afraid and panic?

On the hilly grassland at the southern end of Zhangjiakou, a well-equipped dragon tooth cavalry wearing gray-blue military uniforms suddenly poured out from behind a dirt hill.

They were the cavalry reconnaissance battalion of the Guards Regiment that was ordered to act as the pioneer.

Under the leadership of the deputy commander Zhao Tiezhu, they came first, and as soon as they appeared, they happened to meet some cavalry scouts sent by devils.

The devil cavalry found this loaded Chinese cavalry, and immediately turned their horses' heads as if they were facing a great enemy, and fled back in a hurry.

Seeing this, a cavalry company commander couldn't help but ask Zhao Tiezhu: "Battalion commander, what should we do, do you want to lead someone to chase and kill?" Kill these devil cavalry scouts? ”

Zhao Tiezhu stared at those devils and cavalrymen who were galloping wildly, shook his head and said, "No, we have more important things to do."

After saying this, Zhao Tiezhu suddenly pulled the reins of his war horse and shouted in a deep voice: "Without further ado, the brothers and I will continue to march towards Shaling Town, and we must cut off the contact between the enemy in Zhangjiakou and the Japanese army in Xuanhua and even Beiping."

This is the task assigned to them by Qiao Youhua, using the rapid mobility ability of the cavalry to run long distances, and seize Shaziling, a key place at the eastern end of Zhangjiakou, and cut off the connection between the Japanese army in Zhangjiakou and Xuanhua.

In this way, there was no fear that the Japanese puppet army in Beiping, Xuanhua and other places would come to reinforce it, and the enemy army in Zhangjiakou would either abandon the city and flee north, cross the Great Wall and the Yinshan Mountains and flee to the outside of the pass, or they would only be completely annihilated by the dragon's tooth column on the spot.

With the strength of the Northern Route Army, as long as there is no reinforcement from the Japanese army in Beiping, recover Zhangjiakou, and then recover most of Chahar, Qiao Youhua still has this confidence.

Shaziling is located in Zhangjiakou east of 30 miles, is from the road to Beiping, Xuanhua area must pass through, is also from the west of Beiping out of the plug outside a must road, in addition to this road, there is a river in the south of Shaziling, called Yanghe, the water is deep and the river is wide, Zhao Tiezhu with the cavalry reconnaissance battalion along the dirt road on the bank of the river all the way to march all the way.

It took less than an hour to arrive at the town of Shaziling, where the Japanese army stationed two infantry squads, and these devils and some local puppet soldiers blocked the only road in the town and built a blockade ditch, a group of pillboxes and two artillery towers, just to hold it and control it.

As soon as Zhao Tiezhu led the elite cavalry to arrive, the devils and puppet soldiers discovered their traces, and rushed to all floors of the turret and each pillbox as if they were facing a great enemy, raising their guns and aiming at them, and preparing for defense in a hurry.

Zhao Tiezhu turned his head unhurriedly and ordered: "Let the gunners add up the 60mm mortars for me, and bombard the devil's turrets and pillboxes fiercely, damn, I really think that the Lao Tzu are cavalry, so there is nothing to do about them?" ”

"Yes!" Several battalion and company commanders suddenly agreed, and one of them immediately turned over and dismounted, and led the artillery to prepare, and Zhao Tiezhu also ordered other soldiers, especially the cavalry soldiers equipped with general-purpose machine guns, to immediately prepare for the attack.

It didn't take long for the cavalry battalion to carry six 60-millimeter mortars lined up in a spacious area more than 500 meters away, and after the gunners' correction and aiming, they were ready for shelling.

"Fire!" With the order of a cavalry company commander, six mortars roared one after another, and grenades were fired in groups of six rounds to smash the devils' gun towers and pillboxes in Shaling Town one after another.

The devil's turrets are all brick structures, no reinforced concrete, and there has been no war here, and it has been in disrepair for a long time, so it is not too strong, and it is not a big problem to resist ordinary machine gun bullets and rifle bullets and even grenades.

However, it is somewhat inadequate to withstand the bombardment of mortar grenades with a caliber of 60 mm.

The rate of fire of mortars is very fast, generally a dozen rounds a minute is no problem, experienced gunners are faster, the artillery of the cavalry battalion in just a few minutes, one after another fired dozens of shells at the devil's turrets, pillbox groups.

The deafening explosion sound was endless, and the fire and smoke continued to rise from the ground, completely enveloping it, and waves of violent explosion shockwaves destroyed the devil's turret and pillbox walls, and even more devils and puppet soldiers were blown down directly from the top floor of the turret.

Before the man could hit the ground, he was hit by shrapnel raging in the air and was killed. Bang! Bang! In the earth-shattering explosions, the devils' bunkers and turrets were blown up to crack the walls, the earth and rocks were splashed, and they collapsed one after another, and there were constantly devil soldiers or puppet soldiers crawling out of the ruined turrets and bunkers covered in fire, rolling on the ground, and constantly screaming until they were burned alive or killed by raging shrapnel.

After the fifty shells were gone, the last turret of the devils finally could not withstand the continuous bombardment, and collapsed with a bang, filled with smoke and dust, and the flames were everywhere, and the devils and puppet soldiers inside were also buried alive on the spot.
