siege of Leningrad

The siege of Leningrad (russian: links=no, translit=Blokada Leningrada, Блокада Ленинграда; german: links=no, Leningrader Blockade; ) was a prolonged military blockade undertaken by the Axis powers against the Soviet city of Leningrad (present-day Saint Petersburg) on the Eastern Front of World War II. Germany's Army Group North advanced from the south, while the German-allied Finnish army invaded from the north and completed the ring around the city.

The siege began on 8 September 1941, when the Wehrmacht severed the last road to the city. Although Soviet forces managed to open a narrow land corridor to the city on 18 January 1943, the Red Army did not lift the siege until 27 January 1944, 872 days after it began. The blockade became one of the longest and most destructive sieges in history, and it was possibly the costliest siege in history due to the number of casualties which were suffered throughout its duration. While not classed as a war crime at the time,
in the 21st century, some historians have classified it as a genocide due to the systematic starvation and intentional destruction of the city's civilian population. page 334

Background

Leningrad's capture was one of three strategic goals in the German Operation Barbarossa and the main target of Army Group North. The strategy was motivated by Leningrad's political status as the former capital of Russia and the symbolic capital of the Russian Revolution and the hated Bolshevism, the city's military importance as a main base of the Soviet Baltic Fleet, and its industrial strength, housing numerous arms factories. By 1939, the city was responsible for 11% of all Soviet industrial output.

It has been reported that Adolf Hitler was so confident of capturing Leningrad that he had invitations printed to the victory celebrations to be held in the city's Hotel Astoria.

Although various theories have been put forward about Germany's plans for Leningrad, including making it the capital of the new Ingermanland province of the Reich in Generalplan Ost, it is clear Hitler intended to utterly destroy the city and its population. According to a directive sent to Army Group North on 29 September:

Hitler's ultimate plan was to raze Leningrad and give areas north of the River Neva to the Finns.

Preparations

German plans

Army Group North under Field Marshal Wilhelm Ritter von Leeb advanced to Leningrad, its primary objective. By early August, Army Group North was seriously over-extended, having advanced on a widening front and dispersed its forces on several axes of advance. Leeb estimated he needed 35 divisions for all of his tasks, while he only had 26. The attack resumed on 10 August but immediately encountered strong opposition around Luga. Elsewhere, Leeb's forces were able to take Kingisepp and Narva on 17 August. The army group reached Chudovo on 20 August, severing the rail link between Leningrad and Moscow. Tallinn fell on 28 August.

Finnish military forces were north of Leningrad, while German forces occupied territories to the south. Both German and Finnish forces had the goal of encircling Leningrad and maintaining the blockade perimeter, thus cutting off all communication with the city and preventing the defenders from receiving any supplies – although Finnish participation in the blockade mainly consisted of a recapture of lands lost in the Winter War. The Germans planned on lack of food being their chief weapon against the citizens; German scientists had calculated the city would reach starvation after only a few weeks.

Leningrad fortified region

On Friday, 27 June 1941, the Council of Deputies of the Leningrad administration organised "First response groups" of civilians. In the next days, Leningrad's civilian population was informed of the danger and over a million citizens were mobilised for the construction of fortifications. Several lines of defences were built along the city's perimeter to repulse hostile forces approaching from north and south by means of civilian resistance.

In the south, the fortified line ran from the mouth of the Luga River to Chudovo, Gatchina, Uritsk, Pulkovo and then through the Neva River. Another line of defence passed through Peterhof to Gatchina, Pulkovo,
