Meltyukhov asks the hypothetical question: what would have happened if the Soviets had carried out their initial plan and begun the invasion on June 12, 1941? By that time, German troops had completed preparations for Operation Barbarossa and concentrated themselves on the Soviet boundaries, where in the strip from the Baltic Sea to the Black Sea it had already gathered 81.6% out of the divisions which the Wehrmacht would have on June 21.[21] The remaining troops were in motion and the Luftwaffe had completed re-dislocation after the Balkan campaign, but the "Wehrmacht had neither defensive nor offensive groups [yet], and a Soviet attack at this moment would have placed it in a very complicated position and made it possible [for the Red Army] to tear its forces apart."[22] [23]
