Grand Admiral Raeder, Commander-in-Chief of the Kriegsmarine, gives an order for "the possibility of invading England to be examined" as he thought Hitler might suddenly ask him for an invasion-plan at some point.
After consultation with Admiral Saalwächter, Reader sets up a small special staff for the preliminary work to study an armed conflict with Britain. The studies were the responsibility of Vice Admiral Schniewind, Chief of Staff of the Naval War Staff, and Rear Admiral Fricke, Chief of the Operations Department - both considered by Raeder as among his most competent advisors.
There were to study the possibilities of an invasion of England from the specific technical problem of transport, in addition to the overall naval and military problems. Extreme care was taken to keep the knowledge of this study limited.
The Navy would be the ones who first had to determine weather, and under what conditions, it could be carried out.
