readx; Sun Liren, this person can be regarded as the younger generation in the Chinese Army, and his career in the army is a little different. Pen & fun & Ge www.biquge.info Born in 1900, he was not in the army at the beginning, but first studied at Southeast University, and only after graduation did he apply for the Wuhan Army Military Academy, after graduating from the Wuhan Army Military Academy, he did not directly enter the army with other military cadets and climbed up step by step, but was sent to the Virginia Military Academy in the United States to study, when China and the United States were in a honeymoon period, every year China sent a large number of students to the United States.

After graduating and returning to China, he was promoted relatively quickly, and successfully crossed the threshold of major, and today in 1931, he has already worn the rank of lieutenant colonel and served in the headquarters of the First Army as an operational staff officer.

He was extremely interested in the armored forces, and he put forward a new proposal on the use of armored forces, suggesting that in large-scale breakthrough operations, the consumption of armored forces should be avoided as much as possible in the early stage, and the gap should be opened with infantry and artillery units in the early stage, and then the armored forces should be put into the rapid breakthrough and expand the gap, so that the armored forces can avoid the consumption in the early stage and maintain more combat effectiveness for subsequent in-depth assaults.

This suggestion intrigued Huang Anyuan, chief of staff of the First Army, and believed that if the First Panzer Army did not participate in the first wave of attacks in the early stage of the Anzhou Campaign, but instead entered the battle after the infantry units had opened a gap, they would not have been subjected to stubborn resistance from the defensive forces of the Japanese army, thus avoiding the fearless losses of tanks in the early stage.

In the formulation of the Pyongyang battle plan this time, Sun Liren once again put forward his idea, which was supported by Huang Anyuan, although it was said that several combat plans focused on the rapid assault of armored units, but how to assault was very different.

When the General Staff of the First Army perfected the No. 3 Operational Plan, it was strongly supported by Fang Dashan, the commander of the First Panzer Army, saying that if its armored forces could avoid the attrition of breaking through the enemy's defense line in the early stage, then they would be able to save more strength for in-depth assaults.

The complete concept of the third operational plan is to concentrate at least half of the infantry and more than 70 percent of the artillery and the corresponding air force aviation on the entire front to form a first wave of offensive on the length of the entire front of less than 10 percent, and to use absolute superiority in strength and firepower to smash a certain point of the enemy's first line of defense.

Having made a breakthrough in the first line of defense, the infantry units of the second echelon were quickly thrown in to widen the gap and advance into the depth of the enemy. At the same time, the armored forces were also engaged in battle, and quickly advanced into the enemy's depth through the breach, disrupting the enemy's deployment and encircling the enemy.

The reason for this strategic concept adopted by the First Army is very simple, that is, it wants to preserve the strength of the armored forces in the early stage as much as possible, not to say that a large amount of the strength of the armored forces will be consumed in the early breakthrough battle, as in the last Anzhou Campaign.

Although the operational concept put forward by Sun Liren is already some of the large-depth strategic theory put forward by the Soviet Union in World War II in later generations, it is actually not the same thing, or Sun Liren did not take into account the deeper strategic issues at all.

The purpose of this idea he proposed was very simple, that is, to avoid the consumption of armored forces in the first wave of the offensive. After all, China's current armored forces seem to be quite a lot, but the overall number is not much, and every tank is precious, and the role of these tanks should be to quickly advance into the depth of the enemy's army, and not let it be consumed in the first wave of the offensive.

In order to concentrate more firepower and troops on the predetermined breakthrough front, China's First Army carried out a large-scale mobilization on the front, and although the Third Army on the opposite side also found some delays, the Third Army on the Pyongyang defense line was originally insufficient, even if it was reinforced by three divisions one after another, making the total strength of the Third Army as high as seven divisions, but the eighth division was under the jurisdiction of the former First Army. The remnants that broke out of the early stage of Suchuan were only more than 10,000 people. During the Battle of Anzhou, the 4th Division and the 9th Division carried out a fierce counteroffensive in order to rescue the First Army of Anzhou, and finally not only defeated the interception of China's First Armored Army, but also caused heavy losses to themselves.

After the First Army was almost completely wiped out, the Third Army and the Second Army remained, and the Second Army had already retreated to Wonsan Port, and together with the Third Army, it formed a defensive line nearly 200 kilometers long, stretching from the west coast of Korea to the east coast of Korea. The western defense line was based on Pyongyang and the Taedong River, while the eastern part was based on the Wonsan port and the complex mountains of central Korea for resistance.

The Pyongyang defense line in the mouth of the Chinese generals in Pingyue does not mean that it refers only to the city of Pyongyang, but to the defense line of the Taedong River, which is 100 kilometers wide from east to west.

In fact, only such a long width of the battlefield can accommodate hundreds of thousands of troops on both sides, otherwise it would be impossible to deploy so many troops if it was only ten or twenty kilometers. The width of the deployment of modern troops is very wide, and it is very normal for a division to control the width of the battlefield of more than 10 kilometers.

In modern warfare, in addition to the attack on the fortress, it is basically impossible to see a concentrated charge of thousands of people and tens of thousands of people in the field, and most of the charge battles take place at the company and battalion level, but these battles at the level of hundreds of people do not occur in one place, but on the entire front.

In order to make a breakthrough in the 100-kilometer-long defense line of the Taedong River, the First Group Army concentrated the Eighth Army and the Seventeenth Army to carry out a large-scale river-crossing operation about 30 kilometers southeast of Pyongyang.

When Chen Yi, who was on the front line, looked at the huge explosion sound coming from the military position in the distance, Rao was proud of himself as an army general, but he had to admit that the giant cannon of the navy was really fierce.

When those 16-inch huge shells smashed into the positions of the Yue troops on the opposite side of the Datong River, the explosion area covered almost several hundred meters, and if they hit, it would not be a problem to kill hundreds of Japanese troops with one shot.

In fact, the high-explosive charges of the main guns of the 16-inch battleships in the Chinese Navy were not as good as the 250-kilogram bombs dropped by aircraft, but the blow to morale of the two was not the same, and the sustained firepower could not be compared.

In recent years, the land bombardment of large-caliber naval guns was still very threatening.

In the midst of numerous artillery bombardments and the positions of the Yue army on the other side of the Datong River, the Eighth Army, the main force that crossed the river, had already begun to cross the river.

Assault boats, ordinary wooden rowing boats, small landing ships of the navy, the Chinese First Army concentrated almost all the ships that could cross the river to launch the river-crossing offensive, not only some ships were hit by the bullets of the Chinese army, but some of the ships were even overturned by the artillery fire of the Japanese army.

Before half of the boats crossing the river had rushed over, there were already quite a few casualties, but in Chen Yi's opinion, such casualties were acceptable, and the river crossing operation continued.

The fastest assault boats and small naval landing ships were already close to the shore, and the soldiers on top jumped into the water without paying any attention to the icy water below, and then launched an attack on the river. The machine guns and mortars accompanying the crossing of the river were also quickly pulled down, and then fire support was carried out on some low mounds of earth, and even some mortar crews could not find cover, so they directly set up mortars in the open space for bombardment.

Bullets continued to shoot out of the muzzles of both sides, and then drilled into the bodies of two [***] people, and the riverside was soon covered with corpses, and the river water on the bank had been dyed red, even if the first wave of troops crossing the river suffered heavy casualties, but more Chinese troops were crossing the river one after another, landing from a battalion, then to a regiment, and then a division. In less than an hour, the Eighth Army had already rushed past a division of troops, and after these river-crossing troops had passed, they quickly attacked their own positions and expanded their own riverside positions.

Two hours later, the engineering units had begun to erect large pontoon bridges, and at the same time, more troops were still crossing the river by boat and entering the battle, although the army wanted to launch a counterattack, but in the face of China's sudden launch and investment of two whole armies to cross the river, the third army could not draw more troops from other fronts to reinforce in a short time, and the reserves in the rear also needed a certain amount of time to arrive.

At that time, China's troops crossing the river estimated that all the pontoon bridges had been erected, and when China erected the large pontoon bridges, more troops would continue to enter the battle, and China's armored troops would also cross the Taedong River and advance deep into the south of Korea.

At one o'clock in the afternoon of 7 February, when the Eighth Army of the Chinese First Group Army launched a river crossing nine hours later, the first improvised pontoon bridge had been successfully built, and although this pontoon bridge still could not allow tanks of several tens of tons to pass, a large number of field artillery and several tons of automobiles and armored vehicles had been able to pass, and the main force of the Eighth Army had already begun to cross the river.

At 6 o'clock in the morning of 8 February, after a day and night of intense construction, with the boat-bridge battalion of the First Armored Army as the core, a temporary heavy boat-bridge regiment composed of a large number of boat-bridge troops in China was finally completed, and the steel pontoon bridge was fully able to withstand the passage of T6 tanks weighing more than 20 tons in the armored troops.

Because the tanks equipped in the armored forces weigh as much as tens of tons, and it is inevitable that rivers will be encountered in combat, and with the infrastructure of today's East Asia, there are not many bridges that can accommodate more than 20 tons of tanks to pass, in order to avoid the situation that the river cannot be crossed, China's armored forces have always attached great importance to the construction of large pontoon bridges, and each armored army has a heavy boat and bridge battalion under its jurisdiction, and has a large number of professional pontoon bridge construction equipment, and it is completely difficult to build a pontoon bridge that can accommodate tank traffic in a short time.

After the pontoon bridge was successfully built, the tanks of the First Panzer Army passed through the pontoon bridge under the cover of smoke one after another, in order to provide cover for the river-crossing operation and avoid the pontoon bridge and the river-crossing troops from being hit by enemy artillery fire, the Chinese river-crossing troops deployed a large number of smoke bombs in the river-crossing area, so that the entire river surface was shrouded in smoke, effectively covering the troops that had passed the pontoon bridge.

At nine o'clock in the morning of February 8, in the city of Pyongyang, Gingu Fan San looked angry: "Why hasn't the 24th Division arrived in Songlin yet, it's been nearly twenty-four hours now, why haven't they arrived yet!" ”
