I've been reading a pamphlet from the US, Dept of the Army pamphlet 20-261a entitled "The German campaign in Russia - Planning and Operations (1940-42)". it deals with the planning of the Operation as well as an account of the Strategic situation as seen by OKH during 1941 and 1942. It mentions that on July 21st Hitler asked Walther Von Baruchitsch to submit plans for a campaign against the Soviet Union. He was to take into account the following factors: "The Concentration of Attack Forces would take 4 to 6 weeks. The Military objective would be to defeat the Russian Army or at least to seize so much Russian Territory that the armaments plants in Berlin and Eastern Silesia as well as the Rumanian oilfields would be beyond the range of Russian Air Attacks. At the same time,German ground forces would have to advance far enough to bring important production centres of European Russia within striking distance of the Luftwaffe. The political aims would includethe creation of an independent Ukraine and a confederation of Baltic States under German domination. The Army would need approximately 80-100 combat divisions, the Soviet Union had some 50-75 good Russian Divisions in Europe. If the campaign against Russia was launched that Autumn, some of the German Air power committed against Britain would have to be transferred to the East." (Please note that the use of the terms "Soviet Union" and "Russia" are from the original text.) Its interesting to see how the German preparations for Operation Barbarossa progressed from this initial plan. One thing that strikes me is the complete lack of intelligence of Soviet Strength at the time. I should also point out that the above pre-dates the Marcks plan. From the pamphlet, its not clear who outlined the above factors but the establishment of an independent Ukraine may have been a political masterstroke if it had been carried out, giving the Ukrainians a rallying point to revolt against Moscow. But it was never carried out. Anyways if people come across any info on the planning for Barbarossa please post it in this thread. It would be nice to discuss the issues facing Germany as it planned for the biggest military campaign of its history.
