Three weeks after the Nazi invasion of the Soviet Union in June 1941, Shostakovich volunteered with the Home Guard in Leningrad. As the siege of the city intensified, he worked on his Seventh Symphony, completing three movements before being forced to leave Leningrad and travel east by train. The work was completed in December that year. Initially he gave each movement a programmatic title, but later withdrew them, leaving this epic work as an emblem of heroic defiance in the face of conflict and crisis: ‘I dedicate my Seventh Symphony to our struggle against fascism, to our coming victory over the enemy, to my native city, Leningrad.’
