Leros87 wrote:As part of Operation Sealion the Kriegsmarine planned to have 4 large transports (Bremen, Europa, Gneisenau and Potsdam), supported by the battle fleet (2 battle cruisers, 2 light cruisers and 3 T boats) out of Hamburg sail into the North and Norwegian Seas, unless intercepted. 7 uboats were to deploy off Scapa Flow and the Forth. The pocket battleship was also to deploy in to the Atlantic via the North Sea to raid convoys.
The Heer was to prepare diversionary landings between the Tyne and Forth with 69 and 214 Inf. Divs and Pz Detach 40, all from Norway. The Luftwaffe was to contribute its Air Fleet 5 in Norway.
This operation "Autumn Journey" (
Unternehmen Herbstreise) was in fact just a feint, to divert attention from the actual invasion in Kent and Sussex. The Germans did not actually plan to land anywhere in Scotland or the north of England. The Kriegsmarine did however plan the operation in some detail.
Europa and
Bremen would sail empty (after some simulated loading activity),
Potsdam and
Gneisenau would take troops on board at Hamburg but unload them again at Cuxhaven under cover of darkness. These ships with escorts formed Convoy IV, three others would sail from Norway, see map from Schenk,
Landung in England, p. 369.
The Germans would generate a lot of radio traffic, also from aircraft, to alert the British. The convoys would sail three days before the actual invasion (S-3), and turn back once the Royal Navy had taken the bait or at the latest at 21h30 on S-2. If necessary, the whole operation would be repeated.
No battle cruisers;
Scharnhorst and
Gneisenau were both under repair. The pocket battleship
Admiral Scheer likewise was not yet available in Sept. 1940, as she was undergoing extensive trials in the Baltic following a major refit. The only heavy units remaning - all assigned to
Herbstreise - were the heavy cruiser
Admiral Hipper and the light cruisers
Emden,
Nürnberg and
Köln.
Emden would escort Convoy IV,
Nürnberg,
Köln and some smaller navy vessels formed the
Kreuzergruppe shown on the map
