After the commander-in-chief gave the order to attack, the various units began intense preparations. Liu Hai returned to his headquarters, first confirmed that the communication lines between his headquarters and the various artillery divisions were unblocked, and then notified the artillery divisions to get ready. In addition to the various artillery divisions marking their own firing areas, Liu Hai specially arranged the ghost cannon and Wu Fatzi, because the two of them were attacking the main peak of Shangganling. In order to be able to eliminate these permanent firepower points in one fell swoop when the troops counterattacked, the ghost artillery made careful arrangements for each gun, divided them into sections, and strived to get rid of these permanent firepower points in the first round of artillery fire. Wu Fatzi was responsible for the artillery cover of the 537.9 Heights, Liu Hai told Wu Fatzi a set of methods of returning the wheel artillery, and told him to strive to use artillery fire to eliminate half of the guards above 537.9 before the troops counterattacked, and Wu Fatzi arranged his artillery power according to Liu Hai's orders!

After a day of preparation, the night of the 30th arrived, and there was no sound on the entire Shangganling line, as if there was no war here, it was a no-man's land. Under the tranquility before the war, the volunteer troops in the entire Shangganling area were already loaded with bullets and knives in hand, just waiting for an order! Liu Hai looked at the watch silently, and when the three pointers on the watch pointed to twelve, Liu Hai received an order from Zhi Si, and the content of the order was very simple, just two words, fire! "Let's go!" Liu Hai gave the order, and thousands of artillery pieces of various types prepared for this counterattack began to fire.

"Boom, boom!" A huge number of artillery shells were fired out from the positions of the five artillery divisions, and the dense shells set fire to the entire line of Shangganling, and every position of the US army was bombarded by shells, and every target indicated in advance was being destroyed, especially the rocket artillery. From the No. 6 position on the right to the shelling zone on the west side, the entire Shangganling area was plunged into a sea of fire! The most unbearable thing for the Americans is that the artillery fire of the volunteers can last for half an hour in peacetime, which is already rare, but this time, the ferocious artillery fire lasted for more than two hours and did not stop, and the raindrops of shells still kept falling, and the Americans felt that the Soviets had entered the war!

"General, general, it's not good!" Van Vliet had just fallen asleep, and his lieutenant hurried in like a monkey with a burning ass. "What's the panic?" Van Vliet roared! Anyone who is woken up just from falling asleep will be a little unhappy, let alone Van Vliet. But then the adjutant said it like a machine gun, and this passage was suddenly poured on his head like a touch of cold water, so that Van Vliet immediately collapsed, and he didn't even have time to put on his coat, and immediately returned to his command position!

"Your Excellency, General!" A communications staff officer of the US army came over and said: "Now all our positions in Shangganling have been fiercely shelled by the Chinese, and the intensity and intensity of the shelling are unprecedented, and our artillery positions on the first line, on various high grounds, ammunition accumulation points, and assembly points on the second line have all been hit!" "This shows that the Chinese are going to attack!" Van Vliet said, "Order all troops to hold their positions to the death, and must not allow the Chinese to break through our positions!" "Yes!" After the staff officer finished answering, he returned to his post.

While the Americans and South Koreans were crying and wolf were howling from the surface positions at Shangganling, the tunnel troops who had already been notified were also making preparations. Dozens of days of perseverance let the soldiers of the tunnel troops deal with sudden blasting and harassment every day, the lack of water and food in the tunnel, the air is not smooth, the wounded can not be sent, there is no medicine, the dead can not be transported, the smell is pervasive, these difficulties and hardships have made the soldiers in the tunnel endure the most severe test, it is because they are waiting for the day of the counteroffensive, the soldiers in the tunnel can persevere, and now they have finally waited for this day, dozens of days of grievance and forbearance have finally reached the day when they can break out, when they receive the order to counterattack, There was jubilation in the tunnel! When the deafening explosion on the surface position shook the tunnel, but this explosion sounded like heaven in the ears of the tunnel troops, and all the soldiers wiped their guns, loaded their bayonets, and prepared to rush out, venting all the anger of these dozens of days on the heads of the Americans above their heads.

Before the tunnel troops want to attack, they must pull out the firepower points used to block the tunnel mouth, and the places where these firepower points are built are the dead corners or anti-slope planes of the artillery fire, and the artillery fire cannot knock out these firepower points, and they must be pulled out by the tunnel troops themselves. When the cannon roared, the troops in each tunnel began to brave the shells that fell from time to time, out of the mouth of the tunnel, and by the light of the explosion, they used * bags, blasting canisters and * to remove the fire points on the side of the tunnel in a unified manner, and each tunnel mouth had its own target. After observing and accumulating in peacetime, the tunnel troops have long been ready to take out these firepower points, and now is the right time, after more than an hour of fighting, the demomen of the tunnel troops have removed all the firepower points that blocked the outside of the tunnel and hindered the attack of the tunnel troops, and then waited for the order to attack.

"Division commander, the Chinese are going to counterattack!" The staff officers of the US army helped Cowen, commander of the 7th Division of the US Army, to hide in the anti-artillery hole; Cowen has not had a good day since he came to North Korea, where the artillery is under fire, and the No. 6 high ground alone has been fought countless times, whether it is the US army or the South Korean army, they are all dead, but until now, the No. 6 position is still in the hands of the Chinese. "Tell the troops that they are not allowed to go out of the anti-artillery hole without my order, and they will all stay in the anti-artillery hole for me, and the several artillery regiments in front tell them to transfer their positions, quickly!" Cowan is not a fool, he knows that such a large artillery bombardment by the Chinese is by no means untargeted, so now saving strength and dodging the shelling is king. Cowen's orders worked hard, and when the counterattack began, Cowen's high ground cost the Volunteers a lot of casualties.

In front of the main peak of Shangganling, the ghost artillery ordered each artillery battalion to begin to uproot the enemy's permanent fortifications that had been calibrated; because they were very well prepared, and because all the subordinates of the ghost artillery were good at firing directly at the artillery, dozens of cannons opened fire on the permanent fortifications on the 537.7 high ground that had already been calibrated to shoot at Zhuyuan, almost one cannon at a time, and no matter how strong the permanent fortifications of the Americans were, they could not withstand the direct bombardment of more than 100 mm cannons. The American and South Korean soldiers, who thought they would be able to avoid the shelling by hiding in the permanent fortifications, watched each other's shells with their eyes in disdain, and smashed them in the face as if they had long eyes in the dark night. After a round of shelling, the permanent firepower points on the 537.7 heights had been knocked out, and with the help of ghost artillery, the covering firing of 537.7 had begun, and the dense shells had knocked out a considerable part of the fire points, thus laying a good foundation for the counterattack.

"Listen, after each cannon has fired a hundred shells, stop and wait ten minutes before proceeding to the next round, adding five minutes between each round!" Wu Fatzi said to his artillerymen. After firing a hundred shells, Wu Fatzi's artillery stopped, and at this time, the American soldiers and South Korean soldiers on the high ground rushed out one after another, preparing to resist the attack launched by the other side, while rushing to repair the fortifications that had been blown up. But ten minutes later, Wu Fatzi's cannon rang out again, and the Americans and South Koreans who had already rushed out were blown up and cried out to their mothers! But as soon as the artillery stopped, the other side would attack, and everyone knew this, and the Americans did the same, but after the second round of artillery fire stopped, there was no more shelling after more than ten minutes, so the Americans and South Koreans rushed out again, and the result was that they successfully caught up with the third round of shelling!

According to the results of the reconnaissance, the second echelon of the US army, that is, the troops that Van Vliet was preparing to launch an attack on the Volunteer Army, were concentrated on several hillsides five kilometers behind the main peak of Shangganling, and the two rocket artillery divisions gathered in the direction of the main peak fired devastating at the enemy here! Hundreds of rocket launchers smashed fire dragons on the slopes of the second echelon of the Americans. These second-echelon troops did not expect that they would be smashed on their heads by such fierce artillery fire, so that one South Korean division and two American regiments of the second-echelon suffered heavy losses, and when the rocket artillery firing was over, several slopes were covered with human stumps and corpses that had been blown up, and the American troops who came to the rescue were instantly stunned!

Although there were also two artillery divisions on the right side of Shangganling, in this shelling, only one-third of the artillery was fired by the two division commanders according to Liu Hai's orders. Why? Because Liu Hai knew that this west side was the area used by the commander-in-chief to lure the other two American regiments to attack, and then use the two armies to destroy them, if he showed too strong artillery strength, it was likely to make the other party cancel the attack plan, in that case, the commander-in-chief's siege plan would not be implemented, so Liu Hai deliberately ambushed on the artillery fire to hide his strength!

"Comrades! We have been fighting in Shangganling for almost 40 days, and many of our comrades-in-arms and comrades have died on these two inconspicuous high grounds. I ask you now, follow me and rush forward and retake our positions! The commander of the assault company clenched his gun and said to his fighters. Take back your ground! The warriors below said immediately. Company commander, the artillery has stopped, it's time for us to go! The correspondent next to him shouted. Great, for the sake of the motherland, for the sake of the people, after the order to attack is given, follow me and rush forward to recapture our positions! As soon as the commander of the assault company finished speaking to his fighters, he heard the voice of the signal soldier: "Attack!" "Rush!" The commander of a company rushed out of the shelter and rushed towards the high ground opposite.
