The surprise attack on the "White Tiger Regiment" by the Chinese Volunteers was a classic battle at the end of the War to Resist US Aggression and Aid Korea, and the soldiers of our reconnaissance squad disguised themselves as the South Korean Army, skillfully passed through layers of checkpoints, inserted themselves into the regimental headquarters of the "White Tiger Regiment" of the South Korean Army's ace capital division, and smashed its command organs in one fell swoop, which was the key to our army's victory. The battle was later adapted into a Peking Opera performance and became a household name. However, the Peking Opera is about the process of the surprise attack, and the situation behind it is not described. As a matter of fact, before the reconnaissance squad set off, the South Korean army was informed of the information and strengthened its vigilance. The success of the surprise attack was largely due to the fact that our troops poured more than 1,900 tons of artillery shells on the enemy's positions. Let's first briefly review the story of the surprise attack on the "White Tiger Regiment". The main purpose of the Battle of Geumseong was to teach the South Korean Army a lesson, so that it could recognize the reality and return to the negotiating table. The task of the 68th Division of the 203rd Army of the Volunteer Army was to annihilate the 1st Regiment of the Capital Division of the South Korean Army. The regiment was the elite of the South Korean Army and one of the first eight regiments formed in South Korea in early 1946. Because of his exploits in the battle to defend Xiangyang, Syngman Rhee personally awarded the regiment a new regimental flag, a "tiger head flag", and the regiment was given the title of "White Tiger Regiment". 
After occupying the position, the White Tiger Regiment built a large number of tunnels, circular trenches, light and dark fire firing points, set up barbed wire, and had tanks, planes, and a large number of artillery pieces, claiming that this was an "impregnable" defensive line. But the enemy has shields, and we have sharp knives. The 203rd Division decided to send a detachment of spearhead troops directly into the enemy's regimental headquarters to destroy its command system after the battle began. For this reason, four days before occupying the offensive position, our reconnaissance unit ambushed and destroyed a search unit of the enemy, captured five people, and found out the enemy's troop deployment and fortification deployment, including the location of the regimental headquarters of the "White Tiger Regiment." The 607th Regiment selected 11 experienced reconnaissance fighters led by Deputy Platoon Commander Yang Yucai, plus 2 North Korean liaison officers, a total of 13 people formed the Sharp Knife Squad. At 00:04 on July 14, they disguised themselves as South Korean troops and plunged directly into the enemy's depth while our troops were launching a frontal offensive. After passing through the enemy's first checkpoint, Yang Yucai found that there was an extra person at the back of the team, it turned out that a South Korean soldier wanted to take advantage of the chaos to follow the team to flee south, Yang Yucai took the opportunity to interrogate the password "Gurum Woba" (cloud hail). On the way, they happened to encounter two more stragglers, and the North Korean liaison officer immediately went up to ask them for a password, and the other party replied, "Muwoba." In this way, the enemy's command was confirmed, and the reconnaissance squad continued to move forward. 
When they marched to the south of Yongjin Bridge, they reinforced, and the enemy's troops went to the front line to reinforce the troops, and their successive troops encountered our army's vanguard battalion, and the rearguard troops stopped at the ditch leading to the regimental headquarters of the "White Tiger Regiment," blocking the way of the reconnaissance squad. Yang Yucai made a quick decision, attacked the enemy, and took advantage of the enemy's confusion to pass through the ditch. At 2:40 p.m., the reconnaissance squad came to the enemy's regimental headquarters and was divided into four combat groups according to the actual situation, with the tasks of annihilating the enemy's guard platoon, the artillery headquarters, the regimental headquarters war room, and blowing up the enemy's car. Due to the swiftness of the reconnaissance fighters, most of the enemy had already been annihilated before they could react, and the battle went very smoothly. According to the summary of the "Selected Examples of Campaigns and Operations" compiled by the Military Training Department of the Jinan Military Region Command, after one hour and 47 minutes of fighting, our reconnaissance squad successfully eliminated the regimental headquarters of the "White Tiger Regiment," killed, wounded, and captured 230 enemies, and the commander of the South Korean Army's mecha regiment and the commander of the US howitzer battalion were killed. Lin Yichun, deputy commander of the enemy's capital division, and Cui Xiyin, commander of the "White Tiger Regiment," who were holding a meeting in the war room at that time, were also captured by our troops after they escaped. Only one volunteer soldier who took part in the battle was slightly wounded. 
According to the records of the war history of the South Korean side, in fact, before our army launched the attack, they had already grasped the relevant situation and strengthened the frontal defense. On 11 July, the search team of the 26th Regiment of the South Korean Army sent a detachment of volunteers hidden in the cantonment trenches at the foot of the North Mountain, its main position, and five of them were captured. After interrogation, these people were hidden here on the 7th, and prepared to turn to attack a week later, and there were many hidden trenches like this under their main positions. Therefore, the South Korean Army deduced that the Volunteer Army would launch an offensive on the 13th, and reported the news urgently. The South Korean Army immediately put the 11th Division, which had been used as a reserve for the US army, into its positions, and strengthened the density of frontal defenses and the vigilance of the headquarters. Although the enemy is ready, our troops are still able to quickly defeat him, so that he can be convinced. The reason why the reconnaissance squad was able to successfully eliminate the regimental headquarters of the "White Tiger Regiment" under the condition that the enemy had strengthened its vigilance was also largely due to the powerful artillery of the volunteers. At this time, the Volunteer Army was no longer the Volunteer Army at the beginning of the war, and was equipped with a large number of new artillery, the most famous of which was the "Katyusha" rocket artillery. The logistics of the Volunteer Army have also been greatly improved, and before the Battle of Jincheng began, a total of more than 2,700 trucks were organized to transport all kinds of supplies150,000 tons, including 1.3 million rounds of various artillery shells. 
According to the official war history "History of the War to Resist US Aggression and Aid Korea", the 20th Corps of the Volunteer Army, which was responsible for this combat mission, has a total of 4 armies under its jurisdiction and has more than 1,100 artillery pieces above 82 mm mortars. Liu Fengwen, a veteran of the war, recalled that the target of the 201st Artillery Regiment where he belonged was the enemy's "White Tiger Regiment" position. The 201st Regiment was armed with "Katyusha" rocket artillery, and 4,521 rounds of artillery shells were delivered in place before the war. "Katyusha" is a new type of artillery developed by the Soviet Union during World War II, fully loaded with 16 rockets, fast rate of fire, powerful, and can produce a high-temperature combustion effect. However, his disadvantage is that he is not accurate enough, so he can only fire intensively, forming a covering strike. At 21 o'clock on July 13, the Battle of Jincheng began. According to the battle plan, more than 1,100 artillery pieces of the Volunteer Army were fired at the same time, and after 7-28 minutes of rapid firepower, more than 1,900 tons of artillery shells were poured on the enemy's positions. According to post-war statistics, more than 30 percent of the fortifications on the surface of the South Korean army's positions were destroyed, while 80 to 90 percent of the obstacles were destroyed in the areas where our troops focused on striking and opening up passages. After the artillery cover strike, our troops broke through the forward defensive positions of the four divisions of the South Korean Army within an hour. 
What was the reaction of the South Korean army to such heavy artillery fire?According to the record of Korean war history: "The enemy's artillery suddenly **, it is impossible to figure out how many kinds and how many guns, and the power is so great that if it thunders, it will shake the sky and the earth." "The shells that fell at the same time as the rain turned the main position of the 2nd Battalion on the right flank, the 'Missouri' line, and the location of the observation posts of the battalions into a sea of fire. The commander of the 1st Battalion of the 26th Regiment of the enemy recalled that he felt "earth-shaking thunder roaring" in the fortifications of the command post, and he was blocked in the fortifications before he had time to direct the operation. They also wrote in the summary of the battle: "The enemy's artillery coverage is really impressive. After the artillery attack, the volunteer soldiers quickly rushed to the enemy's position and inserted the second echelon into the enemy's depth, disrupting the enemy's order. In order to hold the position, the commander of the "White Tiger Regiment" decided to put the last reserve search company into battle, and at the same time, the commander of the enemy's capital division sent another battalion of the mecha regiment to serve as a reserve. When the 1st battalion of the regiment was in an emergency, the regiment commander also realized that the regimental headquarters was very likely to be impacted, so he urgently mobilized the regimental guard platoon, regimental headquarters company, and service company to hold the bridge and road leading to the regimental headquarters, but at this time the mecha regiment had not yet arrived, and the enemy's rear was very empty. 
As described at the beginning, the reconnaissance squad of the Volunteer Army encountered its alert troops at the intersection leading to the regimental headquarters, and after a fierce fight, took advantage of the chaos to pass through the intersection. Before the arrival of the enemy's reinforced mecha regiment, he eliminated the command post of its regimental headquarters in one fell swoop. The resourcefulness and bravery of the soldiers of our volunteers were the key to the success of this surprise attack, but the covering blow of more than 1,900 tons of artillery shells also provided an important guarantee for the success of the surprise attack. It was under the blow of our army's powerful artillery fire that the Volunteer Army quickly broke through the enemy's forward defense line, and the enemy had to send all his forces to the front, creating an emptiness in the rear. 
There is a saying on the Internet that sums up the tactics of our army since the beginning of history - if it is poor, it will be interspersed with roundabouts, and if it is up, it will be covered by firepower. With the support of heavy artillery, the volunteer soldiers were like tigers, and after covering the enemy's firepower, they gave full play to their own advantages in tactical intersperse, and the perfect combination of the two not only gave the enemy a taste of being bombed, but also knocked out its command post, which became the key to the victory of this campaign. After tasting the sweetness of artillery coverage, our army attached great importance to the building of artillery units, and in several subsequent battles, artillery also made tremendous contributions.
