I'll return at the moment to the supposed German anti-Soviet 'oil' campaign. The catch is that Germans did not intended to destroy Soviet-held oil fields refineries, but rather to capture them.
IIRC, Maikop fields were producing only 10% of what Baku oil fiels were making. Grozny oil fields were at 20% of Baku? So any bombing of said oil fields will need to wait until a) Germans are definitely certain that those cannot be captured, and b) Germans have adequate force of heavy bombers and their escorts close enough. So the decision to bomb Baku will be issued when, November of 1942? That would mean it is too late for any meaningful large scale operations until snow rain are gone, like April/May 1943? Way too late for anything? The Soviets can have some Spitfire IXs by that time, supported by radars.
