After the start of the counterattack against Vietnam, the PLA quickly ended the fighting in northern Vietnam, and then advanced to the Lang Son area. Lang Son is a vital military point for Vietnam, it is a barrier between the north and the south, once Lang Son is lost, it means that Vietnam has lost its protective cover. To this end, Vietnam urgently adjusted its deployment, focused on deploying defenses around Lang Son, and also transferred the famous "Venus Division" of the Vietnamese army to take command. This is an elite division that has fought with the US military, and its combat effectiveness is quite good.
At that time, Vietnam thought that it had the support of its "big brother" behind it, and it was very arrogant and arrogant, and it did not take our People's Liberation Army seriously at all, and even made wild remarks that it would come to China to celebrate the Spring Festival after winning the war. At that time, the commander-in-chief of our army on the front line was General Xu Shiyou, who had fought for many years and was famous.
The People's Liberation Army defeated the Vietnamese army north of Lang Son at the beginning, but because the other side was familiar with the terrain and carefully deployed, our army also suffered a lot of losses, so Xu Shiyou planned to suspend the offensive first and wait until the artillery unit arrived before continuing the offensive. And the Vietnamese army saw the loss of the north and urgently launched **, which caught the PLA by surprise. It is a shame that they ignored the provisions of international law and actually used the chemical ** left by the US army in the battle, which made the PLA ** miserable, for which our army had to temporarily retreat.
In this regard, Xu Shiyou was furious, since Vietnam does not emphasize martial arts, then our army will no longer shrink back, and directly ordered to raze Lang Son to the ground. At this time, the artillery unit was in place, so Xu Shiyou mobilized more than 300 artillery pieces, bombarded the Lang Son area indiscriminately, the Vietnamese army's pillboxes and fortifications were powerless in the face of countless shells, after the shelling ended, the People's Liberation Army blew the charge to attack, at this time Vietnam also transferred artillery, but it was too late, the shells could not play a good effect.
The People's Liberation Army occupied most of Lang Son under the cover of artillery, and by the fourth day, the main Vietnamese forces were largely annihilated, and the remnants of their troops hastily withdrew from Lang Son, and this tragic battle came to an end. After the war, Lang Son became a ruin, thick smoke billowed everywhere, the number of Vietnamese troops in this battle exceeded 10,000, and our army also sacrificed more than 1,000 people, and more than 4,000 people were wounded. After the war, after Deng Gong understood the situation, he said: The fight was too hard.
This battle can be said to be the most tragic of the counterattack against Vietnam, and the overwhelming shells turned Lang Son into a hell on earth. After seeing the tragic situation in Lang Son, the Vietnamese leaders were also apprehensive, and then they built a mass grave memorial in the local area, believing that this was an evil act committed by the People's Liberation Army in Vietnam, and they also sold misery everywhere in the international community in an attempt to win sympathy.
The Vietnamese army in the Battle of Lang Son was heavy, the ace troops were almost annihilated, and the other main divisions were also heavily damaged, but they still did not give up, thinking that the PLA would continue to attack. But they were wrong, and instead of continuing to advance southward as they expected, the PLA chose to withdraw north.
In fact, China does not want to have a conflict with Vietnam, but it is only Vietnam's in-depth progress that forces China to fight back. This counterattack was not to occupy Vietnam, but to teach them a lesson, so that they would not dare to provoke China at will in the future. However, Vietnam does not want to admit defeat, and waits for time while negotiating, smearing China internationally in a vain attempt to gain the support of other countries.
Since then, the armies of China and Vietnam have been facing each other in the area of Lao Son and Zheyin Mountain, and Vietnam intends to fight a protracted war, but it is obvious that Vietnam has not taken any advantage, but has been suppressed by the People's Liberation Army to the death. Under the deployment of Deng Gong, the troops of the major military regions in China took turns to compete with the Vietnamese army, treating the other party as an opponent in actual combat exercises, and by the way, they also tested a lot of new styles. At that time, although all the people in Vietnam were soldiers, without the support of the Soviet Union, they would not dare to compete with our army with the courage of the two of them. After losing the aid of the Soviet Union in the later period, Vietnam could only choose to bow its head and negotiate peace.
In order to recover their vitality more quickly, China embarked on the road of reform and opening up in the 80s, and its comprehensive national strength has become stronger and stronger. Vietnam, on the other hand, has been deeply affected by the war and can no longer compete with China today, which is the price they pay for their hubris.
