The main objective of the German operation Case Blue during World War II was originally to capture the Caucasus region. This strategic move aimed to secure vital oil fields in the area, particularly in Baku (in present-day Azerbaijan), as Germany was heavily dependent on oil imports. Furthermore, the Germans sought to cut off the Soviet Union's supply routes through the Caucasus, weaken their military capabilities, and eventually bring about the collapse of the Soviet regime. By gaining control over the Caucasus, Germany aimed to gain a significant advantage in terms of resources and geographical positioning, which they believed would contribute to the ultimate success of their military operations.
