The siege started on 8 September 1941, when the last road to the city was severed. Although the Soviet forces managed to open a narrow land corridor to the city on 18 January 1943, the siege was not lifted until 27 January 1944, 872 days after it began.
It was one of the longest and most destructive sieges in history, and possibly the costliest in casualties suffered.
Lifting the siege
The siege continued until 27 January 1944, when the Soviet Leningrad–Novgorod Offensive expelled German forces from the southern outskirts of the city. This was a combined effort by the Leningrad and Volkhov Fronts, along with the 1st and 2nd Baltic Fronts. The Baltic Fleet provided 30% of aviation power for the final strike against the Wehrmacht. In the summer of 1944, the Finnish Defence Forces were pushed back to the other side of the Bay of Vyborg and the Vuoksi River.
The siege was also known as the Leningrad Blockade and the 900-Day Siege.
