Fred, you mentioned that the Germans had achieved air superiority in early August 1940. Some problems with this . The first and greatest being... How can the British stopping sending shipping through the Narrows be interpreted as an indicator of AIR superiority??? It's worth noting that on no occasion did the RAF refuse to or prove unable to react to raids over the Channel during the Kanalkampf. Now THAT would have been an indicator of the Luftwaffe having gained superiority... A lot of people - Fred included - when looking at Directive no. 17 see it as a further directive on the prosecution of Sealion - but it's NOT. Directive no. 17 is the Fuhrerdirectiv changing the Luftwaffe away from its then-current and relatively unplanned strategic bombing campaign....and redirecting it towards a more direct prosecution of the air supremacy battle - BECAUSE it was taking losses too! Losses that were judged to be beginning to impinge in its future role in winning air superiority and subsequently providing close air support for the Landing forces. You need to look closely at Directive no.17...and see what it STOPS happening... 2. After achieving temporary or local air superiority the air war is to be continued against ports, in particular against stores of food, and also against stores of provisions in the interior of the country. Attacks on south coast ports will be made on the smallest possible scale, inview of our own forthcoming operations. I.E "You've been bombing ports and shipping up to now - stop that, carry out Part ONE of the order..." 1/ The German Air Force is to overpower the English Air Force with all the forces at its command, in the shortest possible time. The attacks are to be directed primarily against flying units, their ground organisations, and their supply organizations, but also against the aircraft industry, including that manufacturing anti-aircraft equipment. ..."and THEN GO BACK to bombing shipping, and ports, and food stocks." The Directive goes on to hammer home this point - 3. On the other hand, air attacks on enemy shipping and merchat ships may be reduced except where some particularly favourable targets happens to present itself.... It then stipulates that the new campaign would begin on or around the 5th...but weather wasnt favourable, planning for it wasn't complete nor orders cut for it by the 8th...when part 3. of the Directive was actioned to allowed Hugo Sperrle to plaster the Peewhit convoy off St. Catherine's Point, as is currently being discussed elsewhere.
