ALTHOUGH OUR ARMY HAS TRANSFERRED FOUR 100MM SELF-PROPELLED ANTI-AIRCRAFT GUNS FOR DIRECT FIRE SUPPORT, SO FAR, ONLY THIS TEMPORARY COMBAT SQUAD COMPOSED OF SIX COOKING SOLDIERS HAS RUSHED TO THE GUITUN FORT.

As long as this A-shaped fortification is eliminated, a passage can be opened for the follow-up troops, and the surface position of the Guitun Fort can be quickly deployed at Pingdingshan to control the Guitun Battery.

At this time, Lao Gao didn't know that the head of the Dao Dao was worrying about him.

He pulled out a white phosphorus grenade from his back with his backhand, expertly unscrewed the bottom cover, and slowly pulled the fuse ring out of it.

In order to knock out the Guitun Fort, Yue Zhongwang specially applied to the military department for a batch of white phosphorus grenades and two sharp knives for the blasting task.

Lao Gao lit the fuse according to the bomb throwing training standards, and silently counted "1, 2, 3, 4, 5, bomb!"

In an instant, I saw that Lao Gao's eyes were quick, and he threw this white phosphorus grenade into the shooting hole with great precision.

The Annan soldiers inside the fortifications panicked when they saw a grenade emitting white smoke falling from the sky. One of the veterans rushed over to pick up the grenade and was about to throw it out.

However, as soon as the Annan veteran straightened up, there was a "boom" that blew off his entire arm in an instant.

The white phosphorus that burst out of the explosion instantly covered almost every inch of space in this bunker with an area of about ten square meters.

The six Annan soldiers inside turned into six howling and screaming fire men in the blink of an eye.

This white phosphorus grenade is not an ordinary grenade.

The bomb can be used to burn substances that are difficult to burn with ordinary combustion materials, and can be fully burned in a small space or with low air density, and the temperature of general combustion can reach more than 1000 degrees, which is enough to destroy all living organisms within an effective range.

Everything that is stained with white phosphorus that is exploded will continue to burn until it is extinguished. When it comes into contact with the human body. The skin is penetrated and then deep into the bone.

The blazing flames suddenly burst out of the shooting hole.

"Well done! Who is this warrior? I'm going to give him credit!" Yue Zhongwang clenched his right hand into a fist and waved it fiercely into the air. Said excitedly.

Through the binoculars, on the Guitun Fort in front, Fat Hong, Da Zhou, Xiao Jiang, Xiao Mao, and Shuai Hu all climbed to the bottom of this A-shaped fortification at this time.

The iron gate of a passage more than fifty meters away suddenly opened, and three Annan soldiers rushed out from inside.

Fat Hong and Da Zhou reacted the fastest. Grab the fire now!

The Type 81 assault rifle and general-purpose machine gun instantly smashed the three Annan soldiers who had no time to make any tactical moves into a sieve.

"Fire blockade, don't let the Annan monkeys rush out!" Fat Hong shot with a Type 81 assault rifle. While shouting loudly.

Xiao Mao, Xiao Jiang, and Shuai Hu all lay on the ground smartly after hearing the sound, holding the Type 81 assault rifle in their hands, aiming at the passage without aiming, and holding the trigger and not letting go.

At this time, Da Zhou also set up the Type 81 general-purpose machine gun to form crossfire, blocking the only passage to the top of this A-shaped fortification.

At this time, there was a loud sound of charging horns from the bottom of the mountain, and the soldiers of the Sharp Knife Company rushed one after another from this safe passage opened by the fat flood to the top platform of the Guitun Fort.

5:20 p.m. The 1st Battalion of the 385th Regiment Sharp Knife Company occupied all the surface positions on Pingdingshan and controlled all the air vents and entrances and exits of the Guitun Fort. The method of combining beating and burning was adopted to block all the remnants of the enemy in the fort.

However, since all the passages on the top floor of the inside of the battery were firmly blocked from below by the recalcitrant enemy. For a while, our army could not find a way to destroy the enemy hiding in this fort in one fell swoop. At least 240 or so firing holes were still spewing tongues of fire, providing intensive fire support for the enemy troops stationed at the Tongdeng railway station.

Just when Liu Hongsheng, the commander of the sharp knife company, was helpless with the iron turtle under his feet, the cooking squad leader Fat Hong said with a smile: "Company commander, I have a way to force out all the Annan monkeys inside, but this trick is a little damaged." ”

"Hurry up!" Liu Hongsheng hurriedly said: "To deal with the Annan monkey, the more bad the trick, the happier our head will be!"

"Find some dried chili peppers, the spicier the better!" Fat Hongyin said with a smile: "Throw the big bag of chili peppers into the air vent, and then take a flamethrower to burn the chili pepper buns! If you don't choke the Annan monkeys inside, you have to blind their eyes!"

Liu Hongsheng immediately reported the situation to the regiment commander Yue Zhongwang, and soon, a large number of Chaotian peppers were gathered from the whole regiment.

At Fat Hong's instructions, the flamethrowers carrying flamethrowers on their backs, and the soldiers who used to throw pepper packets all put on gas masks.

Even so, these warriors who performed this trick were choked by the spicy smoke that gushed out and coughed violently, and some of them even had their eyes red and tears flowing.

The soldiers of the Sharp Knife Company were choked on the open-air platform outside, and the fate of those Annan monkeys hiding in the fort can be imagined.

Coughing and howling continued to come from inside the fort, and there was no movement for almost half an hour.

However, at the four passages of the east, west, south and north, not a single enemy army in Annam came out of it and surrendered.

The firing holes on the upper three floors were all muted, but there were more than a hundred firing holes on the bottom two floors that continued to fire.

Yue Zhongwang saw that this damn stubborn enemy was still fighting to the death, and he couldn't do anything for a while.

Individual Cloud Burst Shells were also used, but they didn't work very well.

Obviously, when the enemy built this fort, he took into account the possibility of being trapped, and must have set up multiple levels and different building structures inside, which could cut off the independent space of other floors and passages.

By seven o'clock in the evening, all the stubborn enemies on the heights of Tan and 339 were annihilated, and the Tongdeng Railway Station was also captured.

However, the railway station could not be used for the time being, because there were still nearly 100 shooting holes in the Guitun Fort that had not been knocked out, and the stubborn enemy inside could condescendingly attack the Tongdeng Railway Station with anti-aircraft machine guns at any time.

By this time, the Battle of Tongdeng could be said to have been successfully completed.

But the fly in the ointment is that there is still a remnant of the enemy in the Guitun Fort who is stubbornly resisting and not surrendering.

At this time, Yue Zhong Wangke was really ruthless, and he applied to the military department for 20 tons of explosives, 10 tons of gasoline, and 1 ton of small Chaotian peppers, which were poured into the ventilation hole and carried out a complete blasting.

The whole preparation was carried out overnight, and by the morning of the next day, eight days ago, our troops made the most humane shouting at the southern entrance to the mountain pass. But the Li army entrenched in the fort refused to surrender.

At nine o'clock in the morning of March 6, a big explosion sounded on Pingdingshan, which shook the ground of the entire Tongdeng county.

More than 1,200 officers and soldiers of the 12th Regiment of the 3rd Division of the Annam People's Army were all buried in the ruins of this fort, and none of them came out to surrender from beginning to end.

The last barrier to Lang Son was opened. It only needs to take a further step to conquer Lang Son, and our army can get out of the mountainous area north of Annam, and then to the south is Yima Pingchuan, which can be free to gallop at will by the torrent of steel composed of our army's mechanized troops.

Attacking Lang Son from the front, there is only one road south to Lang Son via Dong Deng, surrounded by mountainous jungles.

The 3rd Division of the Annam People's Army placed its main forces on the various hilltop heights on the outskirts of Lang Son, overlooking the road, forming a dense crossfire.

If all the high ground on both sides of the road is captured, the mechanized units of our army will not be able to smoothly attack the city of Lang Son.

Our 41st Army and 42nd Army, which had combat experience in the Gaoping Campaign and the Tongdeng Campaign, adopted the offensive tactics of fighting steadily and steadily, step by step.

Carry out targeted uprooting of the hilltop heights of the enemy garrison on both sides of the Tonglang Highway.

These hilltop positions are no longer permanent fortifications such as the Guitun Fort, but field positions.

Our army gave full play to the superiority of our artillery fire and opened up a channel of advance with dense bomb landing points. At the same time, a large number of incendiary bombs were dropped.

Each attacking force will form different attack echelons, with battalions as units, adopting squad and platoon evacuation formations, alternately covering, and attacking from multiple directions.

The artillery observation post, equipped with the "Houyi" artillery fire control system, closely follows the infantry forward, provides firing coordinates for the artillery at any time, and calls for artillery support.

Signal flares were fired at each commanding height, and the artillery units immediately launched a 200-meter fire assault to put the next firing point of the defenders of Annam under a dense fire net.

In this way, our army advanced intensively like combing its hair, pulled out the attacks, and knocked out the firepower points deployed by the 3rd Division of Annam on both sides of the Tonglang Highway one by one.

The large minefields set up by the 3rd Division of Annam on the periphery of the positions at Kuma Mountain and Bawaishan Mountain were wiped out under the intensive sweep of our army's rocket minesweepers.

The artillery positions deployed by the enemy behind the main peak, as long as they fire, will immediately be locked by our army's counter-battery radar, followed by more than 130 rocket launchers.

At 9 o'clock in the morning of March 7, our army successfully captured the main peak of Kuoma Mountain and the nearby 417 heights, as well as the main peak of Bawai Mountain.

Because Qixi had long been captured and controlled by our army, at the same time as attacking Tongdeng, the 55th Army of our army carried out a long-distance attack on the Luping and Hengmo areas in the east of Langshan.

Every time a hilltop is occupied, the follow-up engineering units immediately begin construction and build permanent fortifications. All the mountainous heights in the north of Lang Son were firmly under the control of our army.

The battle continued until 2 p.m. on 7 March, and all the points of defense on the periphery of Lang Son had been cleared. The 41st, 42nd, and 55th armies of our Eastern Front Group attacked Lang Son from the east, north, and west.

At this point, all foreign military observers who had been following the war in Hua'an and all countries in the world knew that the occupation of northern Annam by the Chinese army was a foregone conclusion.

Le Duan's strategic plan of first occupying Cambodia and then returning to the northern mountains can be said to be a complete failure. (To be continued.) )
