& now we are back around to a occasionally discussed alternate Mediterranean strategy. Not quite thread jacking, but definitely a digression.
Been ploughing through Barrs 'Eisenhowers Armies'. Am up to page 150 & am still in the background chapters about the preliminaries through 1941 to Ikes appointment as commander of Op TORCH. Theres a lot of random details for the state of British and US forces in 1941-42. Not enough to paint a complete picture, but useful. Whats really lacking are details of the German forces garrisoning France 1941-43. I have some partial items, but not remotely as much as with the US or Brits. A lot can be obtained by going through the the unit histories for the German army, & somewhat for the air and naval forces. But, that is slow and requires much double checking. It does appear the reserve for the Germans in the summer of 1941 were the field forces used in the Balkans campaign, which were neither committed to the opening of the BARBAROSA Op, or the occupation of the Balkans. A infantry corps of a couple divisions and a armored corps. Exactly how those were used in the east later that summer I've not yet followed up on, but they were available in July it appears. Of course other ground and air forces can be formed up for use vs a Brit invasion, but that gives the Red Army, or the Commonwealth in the Med a proportionate break.
In 1942 the rotation of spent formations from the east to the west for reviving was started. Some 'mobile' infantry divisions appeared in France, Belgium, & Germany. A couple burnt out armored divisions as well, plus the first SS armored divisions were formed in France & trained during the autumn and winter of 42. At this point Germany had started its 'long war' mobilization, but the results were not much apparent until 1943.
