The unification of East and West Germany was actually full of competing interests. Germany aspired to reunification, and could pay all the costs, and all countries wanted Germany to be united, but this had a big premise, that is, Germany had to abandon its territorial claims to East Prussia. Germany had to agree, and from then on East Prussia had nothing to do with Germany. In fact, this place was very important to Germany. It was also the place where the German nation rose.
Now this place has been divided between Lithuania, Poland and Russia. From the very beginning, the Prussians developed in this treasure land on the seashore and laid the first step in their rise, which was the origin of all German spirits, so East Prussia became an urgent target for the Soviet army in the Soviet-German war. Just like Stalingrad meant to the Germans. But the Soviets did not take the lead and adopted siege tactics against East Prussia.
The Germans also expressed their resolve by sending the reorganized Army Group Center to East Prussia, where they repelled one Soviet attack after another until Germany surrendered in 1945. From then on this place had nothing to do with Germany. The land of East Prussia was destined not to be returned to Germany. This area was strategically significant and the origin of the German spirit, with the Germans sending 780,000 men to hold out here, originally the scattered Army Group Center. Faced with the near-crushing power of the Soviets, the Germans had no fear, because what they had to hold on to was the tower of the Prussian spirit, East Prussia.
The Soviets, with 1.5 million men on three fronts, gathered heavy equipment and rushed toward East Prussia, but the Germans did not cover it, and they dug trenches in East Prussia to build a fortress, which turned it into a maginot line in the plains. In addition to Army Group Center, there were countless German people here, who also organized themselves into militias, including many elderly people and children.
During the months of the offensive, the area of East Prussia was almost blown up by Soviet bombers, and all traces of Germany were erased. This was the last piece of Land in Germany to surrender to the Soviets. Now, here is The Southern Fortress of Russia, Kaliningrad. What do you think?
