Hitler aims to achieve a speedy victory to destroy the Red Army before the summer ends and the Soviets can mobilize their immense resources. Army Group North, under Field Marshal Wilhelm Ritter von Leeb, strikes toward the Baltic and Leningrad. Army Group Center, under Field Marshal Fedor von Bock, aims to take Smolensk and then Moscow, and destroy communications. Army Group South, under General Gerd von Rundstedt, advances toward the Ukraine and the Caucasus. Soviet forces are caught by surprise and lose a series of battles along the Frontier. German air attacks quickly destroy 1800 Soviet aircraft on the ground. German forces make rapid progress in the north and center but meet stiffening resistance in the south. June 26-29 Politics, Finland Finland declares war on the Soviet Union and launches an attack on the 29th. The Finns aim to recapture the territory lost to the Soviets during the Russo-Finnish War. When they finally achieve this objective, Adolf Hitler asks Marshal Karl von Mannerheim, the Finnish leader, to help Germany besiege Leningrad, but he refuses. June 26-30 Eastern Front, Soviet Union The fortress at Brest-Litovsk is taken after fierce resistance, while the important crossing of the Bug River by Army Group Center begins on the 26th. This group's initial objective is Minsk. The fast-moving panzers encircle Red Army units at Bialystok, Novogrudok, and Volkovysk, leaving them open to destruction by follow-on infantry forces. Unimaginative Soviet linear defensive tactics and weak divisions are proving vulnerable to rapid German panzer advances, especially on the flanks. In addition, Germany's total aerial superiority has led to heavy Red Army losses. June 27 Politics, Hungary The government declares war on the Soviet Union. June 29 Politics, Soviet Union Joseph Stalin assumes control of the federation's Defense Ministry and appoints a five-man council of defense. prev | next |
