The first reason is that the battle marked the end of Germany's invasions into eastern Europe and Russia. The second reason is that this battle was the first major German loss during World War II. It was the largest, longest and bloodiest battle in history, leaving about 850,000 Axis soldiers dead, missing or wounded in the battle, and more than a million Soviet soldiers dead, missing or wounded. Most of the civilians residing in the city also died during the combat, with a total of 2 million casualties.
