The Siege of Leningrad lasted nearly 900 days, from September 1941 to January 1944. As part of Operation Barbarossa, Hitler ordered a blockade around Leningrad, essentially making it inaccessible to the outside world. The blockade prevented food, fuel and all other essentials from getting to those trapped inside. During the winter of 1941 and 1942, citizens were allowed just three slices of bread a day, and many died of starvation.
