The half-arc drawn by Tukhachevski's finger was like a flash of lightning passing through Chu Sinan's mind, instantly causing a mixed feeling of surprise and worry in his heart.

The point that Tukhachevsky pointed to was exactly the front battlefield of the Leningrad Front Army fighting against the German Karelia cluster - the front battlefield of Petrozavodsk. This front line is between Lake Ladoga and Lake Onega, and is far away from Leningrad across the Lake Ladoga region. It belongs to the eastern front of the Leningrad battlefield.

The Gulf of Finland, the Ladoga Lake District, and the Onega Lake District. The three major lake areas in the northern Soviet Union are distributed in the shape of "Chuan". The Ladoga Lake is a vertical line in the middle of the character "Chuan", which just separates the Leningrad battlefield from the Petrozavodsk battlefield in the east.

Since the German army launched a large-scale battle to capture Leningrad, the Northern German army, which broke into the Soviet Union from Finland, has made rapid progress. When the southeastern Finland cluster arrived at the city of Leningrad, another attack cluster advancing eastward, the Karelia cluster, had advanced to the front line of Lake Onega, and launched a flank attack on the Leningrad Front in the narrow area between Lake Radoga and Lake Onega.

Now, Tukhachevsky has briefly stated his strategic offensive strategy, that is, on the one hand, do a good job in Leningrad's defensive operations, and on the other hand, use the German Karelia cluster as the main attack direction, break through and strive to annihilate the German army, and then march along the northern shore of Lake Ladoga, plagiarizing the rear wing front of the Finnish southeast cluster that is attacking Leningrad. If this strategic offensive is finally realized, the Soviet offensive forces can cut off the retreat path of the southeastern Finnish group and block it in Rado

In the narrow corridor between Lake Ga and the Gulf of Finland, together with the Leningrad defenders, the situation faced by the southeastern Finland cluster will be devastating: the Soviet army defended the Leningrad defense line, and the Soviet army encircled the troops, and on both sides of the Ladoga Lake and the Gulf of Finland, there are also the Soviet Red Flag Baltic Fleet and the Artillery Baptistery of the Ladoga Lake District Fleet. In this situation of embattledness, the Finland Southeast cluster has only one road to annihilation besides surrender.

The significance of winning this battle is far from this. If the southeastern Finland cluster and the Karelia cluster can be completely annihilated, the German military's main combat troops in Finland and Norway will be left with the weak Norwegian cluster. Faced with the powerful offensive of the Soviet army, this cluster does not have much resistance at all. In terms of strategic resources, Finland and Norway are crucial to Germany. When these two occupied areas are threatened, the German military base has to draw troops again and invest in these two battlefields, which also makes their troops on the Eastern Front battlefield short of their strength.

If we analyze from the current situation, this battle is also very promising. First of all, the Karelia cluster in Finland is mainly composed of Finnish troops. Among the twenty-seven reorganized divisions, only one is a regular German mechanized division. Compared with the German troops on the main battlefield of the Soviet Union, the Finnish army is much different in terms of weapons, equipment and combat effectiveness. On the other hand, on the shore of Lake Onega, the Soviet army gathered a total of twelve armies of Leningrad, Volkhov, and Karelia, and there are also the 59th and 58th armies that are heading in this direction. At the sea, there are five theater-level fleets including the Red Flag Baltic Sea, the Onega Lake District, the Radoga Lake District, the White Sea District, and the North Sea. In terms of force, the Soviet army has an absolute advantage.

However, if this battle is to be launched, the dangers are obvious. If the Soviet army wants to win the northern battlefield in a short period of time and annihilate the mobile forces of the two Finnish clusters in a large number, it will be necessary to gather the superior forces on the shore of Onega Lake and launch a comprehensive attack on the Finnish army. However, the troops on the battlefield are by no means mobilized. The deployment of each army, reorganized division or even brigade is allocated according to the needs of the war. Any problem in any link may affect the trend of the entire battle situation.

Just like the huge Soviet garrisons on the lakeside of Onega, their garrison here not only serves to resist the eastward advance of the German northern cluster, but also can directly threaten the left wing of the German central cluster attacking in the middle. If this part of the troops is drawn to move north, it will inevitably cause the Soviet military strength in the area to be empty. Once this opportunity is captured by the German army, the Onega Lake area will be fully attacked by the German northern cluster. The German central cluster that loses the threat of the flank will also take the opportunity to launch a comprehensive offensive against the Soviet Northwest Front and Western Front. By then, it will become an unknown whether the Northwest Front, which lacks the support of the right, can withstand the powerful offensive of the German army. Once the defense line of the Northwest Front is broken, not only the northbound army will be attacked from the rear, but even Moscow will be in danger.

War, war, life and death, and one moves the whole body, it will always be so cruel. In terms of military strategy, it emphasizes concentrating superior forces and defeating the enemy one by one. This sentence is easy to say, but it is extremely difficult to do. The concentration of troops in one place will inevitably lead to empty forces in other directions. Therefore, from this perspective, the tactic of concentrating superior forces is itself an adventurous tactic. While concentrating troops, the commander is also making a gambling method. He bet on a time difference: before the enemy breaks his weak links, he can achieve his combat goals. Some people may say that if the troops on one side are

With absolute advantage, isn’t there any danger in concentrating troops? For example, if ten armies fight one arm, even if the forces of four or five armies are concentrated, it may not be dangerous to the main attacking party? Such a way of fighting does not exist for the main attacking party, but in fact, such a super asymmetric war is impossible to appear on the front-on-front battlefield. After all, the party that has absolute military strength advantages knows how to concentrate superior forces to defeat the opponent in one fell swoop, and his opponent is not a fool. People also know what strategic transfer is and what guerrilla warfare is.
