World War II is the most ambitious war in human history, after the launch of the fascist Axis powers led by Germany, Italy and Japan, a total of 61 countries and regions have been involved in this battle, and caused 90 million casualties and 5 trillion yuan of losses, with the passage of time, a sect of ciphertext was disclosed, a lot of news also made us shocked and curious, for example, as one of the Allied Powers of the Soviet Union, in the early days of World War II, he did not seem to play a glorious role. If Germany is a fierce jackal, then the Soviet Union can be said to be a vulture on the branch next to it, trying to divide a few pieces of broken flesh.
In 1941, the German army was invincible on the European continent, and although the Luftwaffe suffered heavy losses in the air battle in London that year, the Nazi regime was still not hurt, their tank armor was still eyeing Britain, and just when everyone thought that Hitler would continue to attack Britain, Hitler unexpectedly turned his gun and pounced on the Soviet Union with 5.5 million German and minions, which surprised the world, because the Soviet Union had just signed the "Soviet Union" in 1939. The Soviet-German Non-Aggression Pact, and also tacitly divided Poland, including Hitler's staff, many Third Reich generals also advised Hitler not to do so, why did Hitler still ignore the opposition of the people?
This may be inseparable from the battle that will be mentioned next, and it is this war that changed Hitler's mind, that is, the war between the Soviet Union and Finland, on November 30, 1939, the Soviet army began to launch military operations against Finland, considering the relationship of time, it is historically called the Winter War.
The contradiction between the Soviet Union and Finland has a long history, since the 17th century, Finland has been part of the Kingdom of Sweden, and then occupied by Russia and Germany, the Finns have not given up their claim to sovereignty, after the outbreak of World War I in the 20th century, the Russian Empire disintegrated, Finland took the opportunity to become independent.
However, he and the successor of the Russian Empire, the Soviet Union, are quite controversial in terms of territory, Finland's territory is close to the Soviet city of Lelingrad, so it is regarded as a threat by the latter, and Finland occupies the ice-free port of Bechaimo in the outer circle of the Arctic Ocean, which has also been coveted by the Soviet Union for a long time, in order to resist the invasion of Soviet forces, Finland has also stepped up industrial and economic cooperation with Germany and other countries, which also makes there is a huge contradiction between the two.
After the implementation of the two five-year plans, the Soviet Union's military-industrial strength was greatly improved, Stalin was also bound to finland, trying to occupy the whole country, on November 26, 1939, the Soviet Union created the "Manilla Shelling" as a pretext to declare war on Finland.
Although the European countries have a sympathetic attitude towards Finland, they are not optimistic about its chances of winning, but the results that surprise everyone have appeared.
During the five-month operation, the Soviet Union invested 1.2 million troops, more than 1,000 tanks and more than 800 aircraft in an attempt to completely conquer the ice country in a crushing posture, and the Finns were also highly morale, vowing to defend their territory, they used all their resources, including the domestic prime-age militia, only 200,000 people, but the Soviet advance was indeed very difficult.
By March 1940, the Soviet Union occupied only a small part of Finland, but suffered 370,000 casualties, while Finland only had 100,000 casualties, and the entire Soviet army was depressed, so the Soviet Union had to sign a treaty with Finland, although this treaty was unfavorable to Finland and lost some land, but they were retained in sovereignty.
The main reason for the defeat of this war was because Stalin launched the Great Purge in the 1930s, which made the Soviet union panic, and a large number of commanders and fighters, grass-roots officers of the army were exiled and executed in the name of political prisoners, which also reduced the combat effectiveness of the Soviet Union. This also allowed Hitler to see the inherent weakness of the giant Soviet Union, which became the reason for his war, of course, after the German action, Finland soon joined the Camp of axis powers, and the reasons do not need to be explained.
