The reason why such a large number of casualties surprised Song Zhewu and even made him feel a little puzzled was mainly related to the memories of his past life that remained in his mind.

In the memory of Song Zhewu's previous life, in the late stalemate stage of the Korean War in his previous life, the U.S. 9th Army launched the Battle of Shangganling in order to control the southern foothills of Wushengshan Mountain, Jinhwa County, central Korea, and its vicinity. The battle lasted 43 days, and in an area of 3.7 square kilometers, the two sides fired more than 2.3 million shells, of which more than 2.1 million were fired by the US military, and about 30,000 casualties were suffered on both sides.

However, in Song Zhewu's memory, the casualties of the volunteer army as the defending side was 15,000, while the U.S. and South Korean coalition forces on the attacking side suffered 25,000 casualties, and the battle loss ratio of the two sides was 3:5. The reason why Song Zhewu suggested building a large number of tunnel fortifications in the fortress was entirely because the famous battle in Shangganling had impressed him too much and too deeply.

In that tragic battle, the reason why the Volunteers with backward weapons and equipment finally won the battle and paid a lower price than the US Army, which was armed to the teeth, was that the Volunteers adopted the method of tunnel warfare, and under the wanton and indiscriminate bombardment of the US Army, they were able to preserve their vital strength and continuously have soldiers engaged in defensive operations.

What puzzled him was that the No. 1 fortress group not only had a large number of tunnel fortifications, but also a better and more complete core bunker fortification than that on Shangganling back then, and at the same time more solid as a fire support point. With such fortifications, how can the proportion of casualties be higher than that of the volunteers and the American army in those years?

Also, no matter how strong the firepower of the Soviet army is, it will never exceed the American army, which just experienced the baptism of World War II in the early 50s, right? Many words must be known that more than 90 percent of the more than 2 million shells and bombs in the Shangganling Battle were fired by the US military, and after the war, the entire hill was blown up and loosened by about 2 meters.

Compared with the current Soviet army, the US army in the early 50s not only has a larger caliber and more number of artillery, but also has heavier aerial bombs and thicker tank armor, and the US army is definitely much stronger than the current Soviet army, and the two sides are not even comparable, but how could the Soviet army let its 39th Army suffer so many casualties in just a few days? Moreover, the casualties on both sides are still so close?

Could it be that the casualty figures of the Battle of Shangganling, which he knew in his previous life, are watery?

Seeing that Song Zhewu stopped the chopsticks in his hand with a worried face, he was silent with the bowl.

Li Wentian said in a solemn tone: "Commander, the 39th Army has not been fought well, and I, the front-line commander, am responsible. ”

Seeing that Song Zhewu was listening carefully to himself, Li Wentian continued: "However, there are indeed some reasons why the battle was not fought well. In addition to the Soviet army's artillery and air superiority, the Soviet army also has some characteristics in combat, which is also the reason for the excessive casualties of our army. ”

"Oh, what's the characteristic? Tell me about it. Song Zhewu put down the bowl and said.

Li Wentian also put down the rice bowl with only a little porridge left, organized his language a little, and said: "For example, the firepower of the Soviet infantry is very fierce. ”

"Their rotary machine guns with cartridges are not only fast-moving, allowing machine gun positions to be established in almost any location, but also have a large ammunition load, 47 rounds at a time, and a long duration of fire, almost two and a half times that of our ZB-26, and our machine guns are often suppressed in counterfire. When the Soviet infantry accompanied the tank charge, the fire was so fierce that we could not raise our heads, allowing the Soviet tanks to calmly approach our position. Even tanks fired directly at the firing holes of the fortifications at great proximity. It was difficult to find an opportunity for anti-aircraft artillery and rocket launchers to strike at Soviet tanks. Part of the fortifications of our first line of defense was lost in this situation. ”

"In addition, the infantry of the Soviet army is very strong-willed to fight, very fierce, will never retreat without an order, and will not hesitate to charge even when facing the muzzle, which puts a lot of pressure on the hearts of our fighters.........,

Although Song Zhewu knew that what Li Wentian said was the truth and his analysis was also correct, he still felt that something seemed wrong, but he couldn't think of what was wrong for a while.

Song Zhewu had no choice but to nod and said, "The regiment of the mountain division that stayed behind enemy lines in the northwest mountains also reported this situation. I have also seen the Soviet army's rotary machine gun in Taiyuan, although the manufacture is crude, but it is conducive to rapid mass production, and it is easy to maintain, it is indeed a good gun. I have already handed over the gun to Zhou Liqun for his reference. In the future, we will also learn from the advantages of this machine gun of the Soviet army. ”

Song Zhewu then said: "As for the Soviet tanks, it is indeed very troublesome, I think it is better to transfer more of our 45mm anti-aircraft guns to them as much as possible to destroy them at a long distance." ”

Seeing that Song Zhewu understood the 39th Army, Tao Rong secretly breathed a sigh of relief in her heart, thought about it and said: "Commander, our first and second two tunnel fortifications are located at the foot of the mountain with slower terrain, once the anti-tank fire is suppressed by the Soviet army for a short time, it is easy for the Soviet tanks to rush to the front, I have seen it with Canxuan, the location of the third tunnel fortification group is on the mountainside, where the terrain is steep, even if the tank drives near the fortifications, it is not easy to find a firing angle......

Tao Rong's words made Song Zhewu's heart suddenly shocked, and he suddenly figured out why the volunteers could defeat the American army with the help of the tunnel.

In his previous life, he had seen it in the movie, in order to resist the heavy artillery and bombs of the American army, the volunteer army built a deep tunnel fortification on Shangganling, except for leaving a few exits, and then there was no shooting hole, the main role was to garrison troops, and to resist the attack or rely on ground fortifications. The main point is that the tunnels and defensive positions are located on the top of steep hills, and American tanks cannot go up.

"When we built the tunnel fortifications, we did not consider the threat of Soviet tanks enough, and the advice of Chief of Staff Tao was very good and ordered Gao Zongbao not only not to fight with the Soviet army for the first tunnel fortifications, but also to blow up the second tunnel fortifications and withdraw the troops into the third tunnel circle. Tell Gao Zongbao again that the No. 1 fortress group must not be lost, and that is the key to whether we can hold Kulun and Beimeng......"

For holding the No. 1 fortress, Song Zhewu is still very confident. He has seen the drawings of the fortress, not to mention that the Soviet army is only attacking the fortress on one side now, and the reinforcements, weapons, ammunition, and baggage of the 39th Army can be continuously transported in, and the wounded can also be sent out in time. Even if the Soviets were besieging from all sides, he believed that the 39th Army, with its complete fortifications, could hold out for at least three months.

"Okay, that's all for the situation at Fortress No. 1, what is the situation on the Eastern and Western Fronts?"

Song Zhewu said as he pulled the rice into his mouth.

It stands to reason that since Song Zhewu's headquarters has been moved to Northern Mongolia, Li Wentian, the front-line commander, should hand over the errand of reporting the battle situation to Tao Rong, who arrived in Northern Mongolia in advance and has fully understood the situation in Northern Mongolia, to introduce it, and Tao Rong's position in the Fourth Route Army is even higher than Li Wentian's. So, Li Wentian turned his face to look at Tao Rong.

But Tao Rong raised her chin and motioned for Li Wentian to introduce the situation.

In contrast, the battle on the Eastern Front was the most difficult.

Zhou Yaoming's 48th Army held off the Soviet troops coming along the Shilka River valley for more than 10 days in the mountains north of Wendu Khan, and every day they had to endure the fierce artillery bombardment of the Soviet ground and the onslaught of infantry, and there were also groups of Soviet planes in the sky that kept diving and strafing bombing. Although the three divisions of the 48th Army took turns to block the attack, the casualties of each division were very large, and the whole army suffered nearly 20,000 casualties. If it weren't for Li Wentian's shooting of the brigade commander who had withdrawn to the exit position in the Shilka River valley without authorization, and the magnitude of the earthquake that deterred the Northern Mongolian troops, several divisions of the 48th Army would have been unable to withstand it a long time ago. …,

The 46th Army of the 5th Mafa had no choice but to withdraw from Krurensi, an important town in eastern Northern Mongolia, after the Soviet army advanced into the Shilka River valley. However, as soon as they left Krulen, a division of the Soviet army crossed the border with a large amount of baggage and moved south, quickly occupied Krulen, and built Kruren into the main station of the Soviet army on the eastern route.

It was only at this time that the true intentions of the Soviet troops on the Eastern Route were finally revealed.

In addition to taking the Soviet army on the eastern route into the Shilka River valley by surprise and disrupting the deployment of the Fourth Route Army, the main purpose was to force the 46th Army of Marfa 5th to take the initiative to withdraw from Krulun. If the Soviet army uses Kruren as a military station, with the flat terrain of the Kruren River Valley, it is enough to ensure the logistics supply of the Soviet army on the eastern route.

It should be said that the Soviet army was very clever in this hand, and it really mobilized the troops of Ma Fawu to take the initiative to evacuate Krulen, so that the Soviet soldiers occupied Kruren without blood.

In contrast, the fighting on the Western Front was the calmest.

After the Soviet army on the Western Front was ambushed twice, although there was no shadow of the elusive Chinese army, this also made the Soviet army a lot more vigilant, the Soviet army on the western route was not only far away from the Soviet Union, but also very far away from the two Soviet troops in Northern Mongolia, if it was surrounded by the Fourth Route Army, the logistics were cut off, it would be very dangerous.

Blyukhel immediately telegraphed the Soviet troops on the western route to stand by and must make up enough for half a month's supplies before they could continue to advance eastward. At the same time, a cavalry regiment was urgently transferred from the Trans-Baikal Military District to the Soviet Army on the Western Route.

After the Soviet troops began to advance eastward on the western route, this cavalry regiment of the Soviet army went out 10 kilometers and carefully searched along the road every day to prevent the main force of the Soviet army on the western route from being ambushed at all times.

As a result, the movement of the Soviet troops on the western route was much slower, and it was still five days away from the ambush site set by Song Zhewu, on the west bank of the Erhun River.

Looking at Song Zhewu, who had put down his job, and after glancing at Li Wentian, he said to Song Zhewu: "Fu Zuoyi commands the 35th Army, the 38th Army, Sun Weiru's 17th Division, and Li Ruifang's Mountain Division, as well as all of them enter the standby area, as long as the Soviet Army on the West Road enters and stops on the west bank of the Huerhun River, the Soviet Army can be encircled immediately." ”

"Very good"

Song Zhewu stood up, paced a few steps on the ground and said: "As long as the Soviet army on the western route is eliminated, Beimeng will be regarded as defending, and the other two Soviet troops must withdraw." The lives of these officers and men who we sacrificed are worth it. ”

Tao Rong hesitated for a moment, and said hesitantly: "However, Fu Zuoyi called and said that he thought it was inappropriate to encircle and annihilate the Soviet army on the west bank of the Hun River...... "......,
