Lvov–Sandomierz Offensive
The Red Army successfully used the Soviet deep battle and maskirovka (deception) strategies for the first time to a full extent, albeit with continuing heavy losses. Operation Bagration diverted German mobile reserves to the central sectors, removing them from the Lublin-Brest and Lvov–Sandomierz areas, enabling the Soviets to undertake the Lvov–Sandomierz Offensive and Lublin–Brest Offensive. This allowed the Red Army to reach the Vistula river and Warsaw, which in turn put Soviet forces within striking distance of Berlin, conforming to the concept of Soviet deep operations—striking into the enemy's strategic depths.
