As far as the French plans for bombing Baku and Batum. It seems like a good idea, but the reality would most likely have been negligible damage. I cant the oil production being completely destroyed by one raid of such limited capacity. Considering the potential attrition rate how many raids were even realistic and the Soviets would be very ready for any further raids.
1/ if you check the link I posted - the Allies planned a night and daybombing campaign, not one raid;
2/ What attirition rate? What exactly were the early-1940 Soviet air assets in the area??? And they hadn't been so successful again very similar if not identical aircraft (uch as the Blenheim) in the Winter War a month or two earlier, had they?
3/ I'm not aware of the Soviets having radar or any other kind of early warning net in the region....so they face the old problem (that Fighter Command sought successfully to eradicate with radar etc.) that fighters without any form of early warning reacting to a raid only get to try to attack them on the way out from the target...and thus only at best can venture half the attrition they otherwise could!
4/ This wasn't an era when for example U.S. oil firefighting expertise could rapidly be airlifted into a liberated Kuwait; the Russians would be attempting to fight rig fires and repair damage and restore supply with 1940s Soviet expertise and capability - and the constant threat of ongoing raids disrupting everything.
