During the summer of 1942 Hitler and OKH had split Germany's Army Group South in two. Army Group A represented the linchpin of the German strategic effort. Army Group A's objectives included the Maikop oil fields (captured during August, albeit after being thoroughly demolished), the Grozny oil refineries, and the Baku oil fields. Together, these oil fields and refineries constituted the overwhelming majority of the Soviet Union's sources of oil.
