At dawn of June 22, 1941, Germany launched Operation Barbarossa, the invasion of Soviet Union. No, not the invasion of Russia. They moved fast, largely because the Soviet armed forces were unprepared, what with the huge purges in 1938, the continuing movement of prisoners east-wards from the Baltic states and eastern Poland and the inexplicable trust Stalin put in Hitler, but they did not reach what we might call Russia for several weeks. By August they were attacking Leningrad and by late November they began the siege of Moscow. Stalin and his mates disappeared from Moscow in June. He did not make a public broadcast till July 3 when he addressed the people of the Soviet Union as "brothers and sisters". According to my mother, who was in Moscow at the time, that caused greater panic than anything else had done.
On June 22 the Germans invaded what was eastern Poland or western Ukraine, depending on your attitude, the territory that the USSR had grabbed in September 1939. They then rolled forward, causing enormous losses though Stalin contributed to that in various ways.
Nevertheless, the date did turn out to be the first real turning point of the war, the second and more important one being December 7, 1941. It was also a turning point in European history though that did not become obvious except to a few individuals like Evelyn Waugh until much later.
Next year will see a couple of important anniversaries: the centenary of the Russian Revolution and the Bolshevik coup, which initiated the existence of possibly the most bloodthirsty political system in history, and the eightieth anniversary of the year that is generally seen as the symbol of Stalin's great purge: 1937. We should devote time to a remembrance and discussion of the victims of Communism.
Meanwhile, here and here are links to more pictures from Operation Barbarossa and its aftermath.
