After breaking through the first regiment of the 3rd Han Division, Liu Xiaoshan almost didn't wait, and immediately gathered his troops to attack Longshui Cave! The reason why he wanted to attack Longshuidong was because Liu Xiaoshan knew that all the field fuel, ammunition and other materials of the 1st Marine Division of the US Army were in Longshuidong, so he was going to attack Longshuidong. The U.S. military equipment is not mentioned, but without sufficient supplies, the firepower advantage of the U.S. military will not be able to develop, the U.S. military is different from our army, there is no habit of fighting with inferior equipment, and it is possible to surrender without supplies!

Liu Xiaoshan sent a reconnaissance platoon led by a guide to clear the way, and at the same time led the troops to advance in the morning light, and in less than half an hour, Liu Xiaoshan led people to rush to the back of the American troops south of Longshui Cave. At this time, the US troops were besieging the 3rd Battalion of the 124th Division that had broken behind enemy lines, and more than 40 artillery pieces and more than 20 tanks were preparing for the next round of attacks behind the attacking troops. But they never expected that the Third Division of the South Korean Army, which did not wait to block the bullets for them, waited for Liu Xiaoshan, who was like a wolf. When Liu Xiaoshan knew that there were 40 artillery pieces and 20 tanks of the US army in front of him, he immediately dispatched an engineer company while marching to form a demolition detachment, and under the cover of the troops' attack, he gathered the ** carried and captured, and prepared to blow up this batch of US military combat weapons!

Liu Xiaoshan's assault capability is not covered, the reinforced battalion is still responsible for the assault, and the two main regiments flank and detour, according to his requirements, to defend and destroy the American troops attacking the 3rd Battalion of the 124th Division within an hour, although he does not know how many American troops there are now. After arriving at the location, there was no combat mobilization, only the bayonet was red, and Liu Xiaoshan rushed forward with people without saying a word. The battle situation is actually very clear, the US army never imagined that they would kill the volunteers behind their backs, and before they could react, Liu Xiaoshan broke through the defense of both wings and surrounded them south of Longshui Cave! Liu Xiaoshan led the assault battalion all the way to break through the formation, and in less than half an hour, he rushed all the way to the surrounded third battalion. After the contact, Liu Xiaoshan was taken aback, because the US army unit that attacked the third battalion was a reinforced regiment!

"Brigade Commander Liu, it's already dawn, the US planes are coming soon, the strength of the enemy's reinforced regiment, we can't eat it at all, it's true to retreat quickly!" The commander of the third battalion was already wounded, and when he heard that Liu Xiaoshan wanted to destroy the American troops in front of him in one go, he persuaded him. "A reinforced regiment? It seems that there is some difficulty, and we do have some difficulty eating it! Liu Xiaoshan said. yes, let's retreat! The third battalion commander said. In this case, I'll let a regiment cover you to withdraw first, and I'm still going to do something! Liu Xiaoshan said. Don't do anything, now the U.S. military is indeed blinded by you, but when they recover their strength, it will be difficult to break through! The commander of the third battalion said anxiously, he himself was too far away to be surrounded by the US army, and he had planned to donate his life, but he didn't expect that he would have someone to save him.

"Third battalion commander, if this is not the case, I will call the two regiments to come here to concentrate, and when the troops are ready, we will withdraw to the east and break away from the eastern front!" Liu Xiaoshan said. "Okay! Anyway, it's been a day and a night, and it's not bad for this hour! "The commander of the third battalion is not a bad breed, so he immediately agreed. In fact, Liu Xiaoshan did this for a purpose, that is, the two regiments were concentrated here from both flanks, although they could not destroy the US troops, but they could disrupt the US troops or completely mix with the US troops, only in this way, even if the US planes came, he could not attack. "Third battalion commander, you send a company to cover my engineering company to attack the artillery positions and armored vehicle assembly areas of the American army!" Before Liu Xiaoshan finished speaking, the third battalion commander immediately shouted, "No problem!" ”。 This day and night of blocking battles made the 3rd Battalion fed up with the sins of these US artillery and tanks, and it was naturally not said that they could have the opportunity to vent this evil breath.

And Liu Xiaoshan himself did not change his original intention, and took a company to make a mess of the US army, and killed the US army in Longshui Cave coldly, the US army guards in Longshui Cave only had one platoon, and he did not expect that there would be volunteers to kill him, but Liu Xiaoshan easily killed the guards and stuffed * and * into the US army's field warehouse. All the ammunition and materials prepared by the 1st Marine Division for this offensive on the Eastern Front were destroyed by Liu Xiaoshan, and the sky-high explosions and burning flames soared into the sky! "Well done, I see how he fights Lao Mei! Remove! ”

After finishing this vote, Liu Xiaoshan returned to the position of the third camp, and at this time the engineer company also completed the task, destroying most of the more than 40 artillery pieces and 20 tanks of the American army, but at this time the American army had already relieved its strength and concentrated the strength of the two battalions and began to counterattack. Due to the heavy damage to the artillery and tanks of the US army, without these strong firepower, the US army could only watch Liu Xiaoshan fight and retreat, slowly withdraw from the battle, and withdraw to the western front! Liu Xiaoshan fought this battle in a very timely manner, and disarmed the 1st Marine Division of the US Army at once, so that the US offensive on the Eastern Front had to stop and wait for ammunition and fuel supplies, the threat on the Eastern Front was gone, and the Western Front was safe! Due to the firepower and aircraft interference of the American army, the unfinished Battle of Yunshan was injected with new strength, that is, Peng Dehuai's 40th Army, which was ready to fight and block in order to prevent the American troops on the eastern front from turning to support the western front, joined the Battle of Yunshan. However, Peng Dehuai was still cautious, because when the 40th Army arrived, the troops of the 39th Army had already pushed the Battle of Yunshan to an end with the artillery support of Liu Hai.

At this time, Palmer of Unshan was already crying without tears, the retreat road of the southern front was blocked, the South Korean army was scattered, the volunteers were still attacking, their own defensive depth was constantly decreasing, and there were hundreds of wounded lying in the defensive circle of the core position, fortunately, the volunteers had a firepower weakness, otherwise they would have been dead for a long time now! The only good news is that the reinforcements in the south are about to break through the resistance of the volunteers, and as long as they can open a passage, their eighth regiment can escape! But the heavens did not fulfill people's wishes, and just when the blocking troops were about to be unable to withstand it, Liu Xiaoshan, who had withdrawn from the Eastern Front, arrived!

"Brigade commander, we have received an order to take over the position of the 322nd Regiment of the 118th Division, block the US army's withdrawal from the north and south, and buy time for the troops in Yunshan to destroy the enemy!" The correspondent passed the new order. "! Lao Tzu just came back, don't they know? Is it easy to go so far from the Eastern Front to the Western Front? It's really like Lao Tzu is iron! "Liu Xiaoshan ran all the way, and at this time he was exhausted and needed to rest urgently." So what to do? The correspondent asked. What can I do? Tell the brothers to drum up more and go to bed when they're done! Although Liu Xiaoshan complained, he still carried out the order! Liu Xiaoshan led people into the position of the 322nd Regiment and set up a position to fight a blocking battle, but the American army began to retreat! Liu Xiaoshan was taken aback by the retreat of the American army, the enemy of Yunshan had not been eliminated, and the reinforcements of the American army retreated, something was wrong, and the situation was reported immediately! This situation attracted Wu Xinquan's attention, but it was still a step too late, allowing the 8th Regiment of the 1st Cavalry Division of the US Army to retreat!

The reason why the U.S. troops retreated was because a South Korean guide told Palmer that there was a small road to the southwest of Unsan that could retreat south, and that it would only take an hour to evacuate from Unsan! Hearing the news, Palmer felt like a lifesaver and immediately began to decorate! Palmer ordered the 8th Battalion of the South Korean Army, that is, the battalion commander who warned him to be careful of the CCP army, saying that he would lead the team to launch a counter-assault and destroy the current CCP army in one go, so his battalion needed to hold on to the spot for an hour, and all the artillery and remaining tanks of the US army were reinforced to him! After giving the order, Palmer couldn't wait to start retreating along the path with the remnants of his troops, and contacted American planes to cover and clear the way for him when he retreated. The battalion commander of the South Korean army who was ordered to stay and hold on was not a fool, otherwise he would not have warned Palmer before the battle, but now Palmer still swore that he would lead the troops to counter-assault and destroy the current volunteer army, he really thought he was a fool, and as soon as the American army left, the battalion commander also retreated along that path with his people!

But as soon as he was negligent, Palmer forgot that he was cooperating with reinforcements to break through the third battalion of the Volunteer Army's defense line, and when he remembered, the third battalion was already surrounded by the Volunteer Legion! Finally caught a big fish, it was impossible to let him go. The 3rd Battalion of the U.S. Army, at this time a feeling of despair enveloped everyone. The Volunteer Army's pursuit shells continued to fall into the encirclement, and the casualties of the American troops continued to increase, and at this time there were only more than 450 people left, of which more than 200 were still able to move. The commander of the 3rd Battalion, who was on morphine for life, decided: all the wounded would be left behind, led by the captain of the military doctor to surrender to the Chinese, and the others would disperse after dark to break through. This was the last decision made by the commander of the 3rd Battalion. More than two hours later, the commander of the 3rd Battalion died of his wounds.

The hard days passed. As night fell, the breakout operation of the American army began. However, the Volunteer Army moved faster. The U.S. troops who broke through did not climb a few steps, and the general attack of the 345th Regiment of the Volunteer Army on the besieged U.S. troops had also begun, blocking the U.S. troops head-on and taking advantage of the situation to break through the U.S. positions. After a night of fierce fighting, the third battalion of the US Eighth Cavalry Regiment was completely annihilated, and the battalion commander, battalion staff officer, and four company commanders were either killed or captured. As a formed unit, the 3rd Battalion no longer exists. The U.S. Army was forced to revoke the number of the 3rd Battalion.

The Battle of Yunshan ended at this point. The first contest between the Chinese and American armies on the Korean battlefield ended in the victory of the volunteers. In the battle of two days and three nights, the 39th Army of the Chinese People's Volunteers inflicted heavy losses on the First Cavalry Division of the US Army, killing, wounding, and capturing more than 2,000 US and South Korean troops, including more than 1,800 US troops, shooting down three planes, capturing four planes, destroying and capturing 37 tanks, more than 100 automobiles, and more than 100 artillery pieces of various kinds. This was the worst defeat in the history of the U.S. 1st Cavalry Division. Commander-in-Chief Peng Dehuai said happily: "The 1st Cavalry Division, the 'winning division' of the United States, which has never suffered defeat, has suffered defeat this time, and it has been defeated under the hands of our trump card--- 39th Army!" ”
