Originally, the soldiers of the ROK army of that battalion were stationed in the military fortress of Xiajieyuli and had to take dozens of military trucks to the hillside five kilometers away on the south side to attack the volunteers of the Sharp Knife Company, who were already on standby in the trenches and air-raid shelters, with less than 200 people.

However, before the departure of the South Korean battalion commander, he submitted this application to the commander of the US Army, Colonel Madeep, but was ruthlessly refused, and the reason given by Madeep was that they only let a battalion of South Korean troops go to a hillside area about five kilometers away, the distance is very short, and there is no need to take military trucks and other transportation roads, and they can march directly on foot, which saves time and effort.

As a matter of fact, the reason why Colonel Madip, the commander of the US Army, really rejected Lee Doo-hyun, the commander of the ROK battalion, in the depths of his heart was that all these military vehicles left in the lower corner were provided by the US military, and naturally they should be used by the US soldiers first, and the soldiers of the ROK army could only stand aside, and if it were not for a particularly urgent situation, they would not be qualified to use these military vehicles provided by their US military at all.

What's more, when they left the military fortress of Xiajieyuli and marched south for less than two kilometers, it was already an undulating hillside and hilly area, and the military vehicles could not continue to drive south at all, but only a burden for marching and fighting, and it was better to march on foot than to take a vehicle to march.

The most important point is that in the previous more than a month of fighting, countless military vehicles of all kinds were lost from the ROK troops, and the vast majority of those military vehicles that were not destroyed fell into the hands of the Chinese volunteer troops who launched an attack to the south.

In the face of the ruthless refusal of the commander of the US Army, Colonel Madip, the commander of the South Korean battalion, Lee Doo-hyun, felt that he would have to be controlled by others, so he had no choice but to take the soldiers of his battalion out of the south gate of the fortress in Xiajieyuli after breakfast, and walked towards the hillside area five kilometers to the south.

Although, more than a month ago, in the area of Onjeong and Cheongcheon River, the well-armed and well-equipped Korean troops led by Lee Doo-hyun at that time suddenly had an encounter with the raiding Chinese People's Volunteer Army troops, which eventually led to the almost total annihilation of his battalion of Korean troops.

Seriously wounded, with the help of military staff officer Kim Sung-ki, he crossed the ice-covered Cheongcheon River and came to the rear hospital of the US army, which saved his life. If it weren't for that, he would have died on the battlefield long ago.

It can be said that when Li Douxuan faced the Chinese People's Volunteer Army, he had lingering fears, and at the same time, deep in his heart, he still hoped to make up for the big loss he had suffered before.

At this time, he felt that he was leading this battalion of ROK troops, with more than 1,000 troops, and that the small force of the Chinese Volunteers, which was less than 200 people on the hillside five kilometers to the south, showed a huge advantage of more than 5 to 1 in strength.

In addition, although Colonel Madeep, the commander of the US Army, did not agree to let them ride in military vehicles this time, he allocated them a lot of sophisticated American weapons and equipment, and generously gave them as many as 10 mortars and more than 500 shells. In addition, there are twenty light and heavy machine guns,

With so many heavy weapons, Li Doo-hyun, the commander of the South Korean army, felt that he was above the Chinese volunteer army that did not fight 200 people in terms of troops, personnel, and weapons and equipment.

However, what the commander of the South Korean army battalion, Major Lee Doo-hyun, did not expect was that he led the South Korean army troops of this battalion to march on foot for about half an hour after marching on foot for about half an hour when he was discovered by the three companies of sharp knives of the Chinese volunteers on the hillside.

At this time, it was already half past nine in the morning, and for the soldiers of the first platoon of the five squads who were responsible for the vigilance task in the trenches, they only needed to survive another half an hour before they could hand over the vigilance task with the soldiers of the second platoon.

Sun Lei, the leader of a platoon of the third company of the Sharp Knife Company, who was responsible for guarding the north side of the hillside, picked up the telescope and observed it for a few seconds, and found that there was an enemy situation about two kilometers north of the hillside where they were located.

Because he couldn't see it particularly clearly through the telescope, Sun Lei didn't dare to be sure what kind of troops the enemy was rushing in the direction of their hillside, how many troops there were, and what the situation was with weapons and equipment, so he didn't report this matter to the company commander Zhao Yifa and instructor Wang Wenju like a frightened bird, but continued to stay where he was and observe.

After continuing to observe for about five minutes, Sun Lei learned some about the situation through the telescope, and then hurriedly ordered the soldiers of the five squads in the platoon who was in charge of the vigilance task with him, so that they could be vigilant and ready to meet the battle at any time.

Immediately afterwards, Sun Lei rushed to the front of the company commander Zhao Yifa and the instructor Wang Wenju, and reported in a slightly nervous tone: "Company commander, instructor, I just discovered the enemy situation on the north side of our hillside, less than two kilometers away.

"I have made a preliminary judgment on the enemy situation with my observations, and most of the enemies who attacked our hillside this time were South Korean soldiers. Based on my visual observations, the number of troops is probably around 1,000. Moreover, among the weapons and equipment they are equipped with, there are not only one American rifle for each soldier, but also dozens of machine guns and many mortars. ”

After listening to Sun Lei's report, instructor Wang Wenju thought for a while, and then muttered to himself in some confusion: "Did the South Korean army unit near us on this hillside not know about our existence, but passed by here unintentionally, or did they come out of the military fortress in Xiajieyuli in order to attack us?" ”

After pondering for a moment, Zhao Yifa, the company commander standing on the side, said in a firm tone: "Instructor Comrade Zhao, what do you want to do so much, don't care where this South Korean army unit comes from, as long as they are close to us, it will pose a very big threat to us."

"In my opinion, we have room to wait here so that they can find out that they are passively beaten, but it is better for us to strike preemptively and take them by surprise. Anyway, we are now in trenches and bomb shelters, and we are not afraid of their heavy weapons. ”
