Ouyang Yu, who had a wealth of troops, ordered the remaining troops not to care about the enemy in the encirclement, and asked them to move quickly along the opened passage to expand the results of the battle, and a tank brigade and three infantry regiments converged with the attacking troops in front of them along the passage, and soon came to the second fortification area of the Mannerheim Line.

The second fortified area is the core position of the Mannerheim Line, the Finns have carefully built a large number of permanent fortifications, countless bunkers, and the two most elite divisions of Finland are also arranged here, as long as the Mannerheim Line is captured here, it can be declared breached, and the rest is the plain that is most conducive to the attack of mechanized troops, and then Finland will have no danger to defend but surrender.

In the second fortified area, Ouyang Yu still adopted the same way of playing, boom, with the most intense artillery fire and bombardment, completely erasing the Finns' positions from the face of the earth.

At 14:24 p.m., a huge group of Soviet planes dropped a large number of bombs on the second fortified area, and each of the 120 SB-2 bombers was loaded with two 1,000-kilogram bombs, which were specially used to destroy the large Finn bunkers, and no matter how strong the Finns' bunkers were, they could only be turned into a pile of ruins in the face of 1,000-kilogram bombs.

Ouyang Yu prepared 24 B-4 203 mm howitzers and 48 M1937 152 mm howitzers, which were specially used to destroy the large pillboxes that survived the bombing, and the large pillboxes that survived under the guidance of the reconnaissance aircraft were uprooted one by one.

At 16:31 p.m., the Soviet ground forces began to attack, still in the vanguard of KV tanks, with more than 100 T-28 tanks and three divisions of infantry slowly advancing.

By this time it was already dark, which helped the Finns somewhat, but the difference in strength between the two sides was too great. The help of the night was very limited, and the small detachments used by the Finns in the past could not be used when the battlefield was filled with Soviet soldiers, and guerrilla warfare had to have a roundabout space, and guerrilla warfare would become a face-to-face positional war without a suitable roundabout space.

Ouyang Yu withdrew her troops as soon as it was dark in the first two days of fighting, making the Finns think that she did not dare to engage in large-scale night battles. Marshal Mannerheim also deliberately prepared a night battle plan, wanting to take advantage of the long winter nights in Northern Europe to recapture the lost position, but he did not expect Ouyang Yu to be unusual, not only did not stop the attack when it was dark, but instead increased the intensity of the attack and invested more troops into the attack, which not only made Marshal Mannerheim's counteroffensive plan abort, but also put the last reserves into the battle in advance.

At 5:16 p.m., the sun had completely set and it was completely dark. But the battlefield was not dark, and the Soviet mortars kept shooting flares into the sky, illuminating most of the battlefield as white as bones.

The Soviet soldiers were not in a hurry to move forward, they obeyed Ouyang Yu's orders and fought steadily, trying to destroy the enemy's living forces, consuming the enemy's strength and energy, and then launching a fierce attack when the enemy was exhausted.

A platoon of Soviet soldiers bent over and advanced on an S-shaped route to cover each other, advancing more than a hundred meters. A machine-gun bunker in front suddenly opened fire, knocking down several soldiers at the front. The remaining soldiers were pinned to the ground by machine guns, unable to move.

Soon a T-28 tank was called, the two machine gun towers in front of the T-28 tank fired fiercely to suppress the Finns' machine gun bunker, the main turret began to rotate and prepare to solve the bunker with one shot, the front armor of the T-28 tank suddenly burst into flames, and then there was a big explosion, and the turret was blown up by the blast wave of the explosion to more than ten meters in the air. After falling, two hapless Soviet soldiers were stoned to death.

"Anti-tank guns!

"Comrade platoon commander, I saw it, there!"

The Soviet platoon commander looked in the direction indicated by the shouting soldiers and saw that there was another anti-tank bunker about forty meters to the left of the machine-gun bunker.

"Cunning guys, call in the artillery and blow up all these damn bunkers!"

In order to ensure that the troops can attack smoothly. Ouyang Yu arranged a large number of fire observers into the company and platoon level troops, and through the fire observer company and platoon commander, he could directly call the artillery in the rear to carry out accurate artillery bombardment.

The fire observer poked out half of his head from behind the cover, closed his left eye and stretched out his right hand to stand up with his thumb, then closed his right eye and opened his left eye, estimated the horizontal distance between the two eyes to see the thumb, and then multiplied this horizontal distance by ten to get the approximate distance of the measured target, and after calculating the approximate distance, the fire observer found out his current position, plus the distance between himself and the bunker, and obtained the specific coordinates of the bunker. (This algorithm is a commonly used eye-jumping method in our army, and interested students can spend their own time.) ）

"Little Bear Ninety-Nine calls the Bear Nest, please fire at small targets in the **** area, repeat ......!"

The call of the front-line fire observer was received by the artillery command center in the rear, and hundreds of radio stations in several large tents and the liaison officers who operated them were very busy, and all the artillery fire requests on the front line were sent here, and then the liaison officers sent them to the corresponding artillery groups according to the targets being shelled, for example, small targets will be handed over to the 76 artillery to deal with, medium targets will be handed over to the 122 artillery to be eliminated, and large targets will be handed over to the 203 artillery guns, which can effectively improve the efficiency of the use of artillery, so as not to cause repeated strikes and waste of firepower.

A few minutes later, more than a dozen shells flew in from a distance, suppressing the infantry's machine-gun bunkers and anti-tank bunkers into the sky.

"Forward, Davarich!"

"Dirty......!"

When the sun rose the next day, the last pillbox in the second fortified area was planted with a red flag, after a night of fierce fighting, the Mannerheim defense line of the Finns was completely breached, the first armored army paid a huge price in this battle, more than 10,000 casualties, more than 70 tanks were destroyed, countless ammunition was consumed, but the price was also gratifying, more than 20,000 Finnish soldiers were eliminated or captured, the three most elite divisions of Finland were disabled, and the Finns were no longer in danger to defend, and the day of victory was approaching.

On January 16, 1940, Vyborg, the second largest city in Finland, was captured, and Ouyang Yu entered Vyborg as a victor.

On January 18, 1940, the Finnish government surrendered and signed the Moscow Peace Agreement with the Soviet Union, which cost Finland the Karelian region, including Vyborg, Finland's second largest city, 10 percent of Finland's arable land and one-fifth of its industrial output. The 222,000 inhabitants, 12 percent of Finland's population, were deported from their homes, and only a tiny fraction of the population chose to remain as Soviet citizens.

Finland also ceded the Rybachi Peninsula in the Barents Sea, four islands in the Gulf of Finland, and part of the Sara region, and leased the Hanko Peninsula to the Soviet Union as a naval base for a period of thirty years. This agreement was very harsh for Finland, and only a year later, an ongoing war broke out with the Soviet Union with the support of Germany.

After the signing of the agreement, the commander-in-chief of the Finnish army, Mannerheim, said bitterly: "The treaty has had disastrous consequences for the strategic position of our country. We have lost all the points that would have guaranteed us to stop the advance of the invading army. The new state borders expose Finland to the aggressor, and Hanko is like a pistol pointed at the heart of our country. ”

No matter how loudly Marshal Mannerheim wailed, no matter how much the Finns cried, it was already useless, they were defeated, this is the truth, if you want to regain what you have lost, you have to be strong, and no one will pay attention to the cries of the weak.

Ouyang Yu was summoned by Stalin after returning to Moscow, Stalin restored her rank of lieutenant general, but kicked her back to the Frunze Military Academy, but this time she was not relieved of her position, Ouyang Yu's combat command during his time in Finland has been sorted out by the Military Academy and compiled as a professional textbook for senior generals, Stalin needs her to teach more, excellent military talents like her come out, so she was ordered to return to the academy, but Ouyang Yu was not interested in teaching, and after returning to the academy, she returned to the other world with the textbooks。 (To be continued.) )
