What is the significance of the siege of Leningrad?
The siege of Leningrad during the war on the Eastern Front lasted for more than 900 days. Stalin and the Red Army had turned the city on the Neva River founded by Peter the Great into a fortress. While it wasn't that militarily important, it was a thorn in Hitler's side, and he had to waste valuable time and resources laying siege to the city. These were troops he couldn't use elsewhere to support the invasion.
Inside the city, life was almost unbearable. Food ran critically short. People took to boiling the leather in their shoes into a weak, unsatisfying soup in order to stay alive. One million people died, but the city was never taken.
