The Siege of Leningrad

S1, E5: Leningrad, a vital and large Baltic sea port, is facing the entire weight of Army Group North. The Soviets have no reserves to spare as the Battle of Moscow is about to begin. Wilhelm von Leeb's Army Group North fails to take Leningrad, but begins a horrible siege that will last 872 days, in which over a million civilians will die of starvation and disease.
