Operation BARBAROSSA - the German Surprise Invasion of Russia’s Polish Holdings: 22 June 1941
On June 22, 1941, having postponed the invasion of Russia after Italy's attack on Greece forced Hitler to bail out his struggling ally in order to keep the Allies from gaining a foothold in the Balkans, three German army groups struck Russia hard by surprise. The Russian army was larger than German intelligence had anticipated, but they were demobilized. Stalin had shrugged off warnings from his own advisers, even Winston Churchill himself, that a German attack was imminent. (Although Hitler had telegraphed his territorial designs on Russia as early as 1925–in his autobiography, Mein Kampf.) By the end of the first day of the invasion, the German air force had destroyed more than 1,000 Soviet aircraft. And despite the toughness of the Russian troops, and the number of tanks and other armaments at their disposal, the Red Army was disorganized, enabling the Germans to penetrate up to 300 miles into Russian territory within the next few days.
