In Britain they may have hopes that the fuel situation in Germany will develop unfavorably. It is necessary to clear up the question of whether a direct operation could bring Britain to her knees, and how long this would take. Also diplomatic steps must be taken in regard to Spain, Russia, and Japan. Such steps are difficult, though, as long as the world awaits a new miracle which has not yet occurred.

The invasion of Britain is an exceptionally daring undertaking, because even though the passage is short, it is not merely a question of crossing a river, but of crossing a sea which is controlled by the enemy. Forty divisions will be necessary. The most difficult task will be the continuous supply of materiel and foodstuffs. We cannot count on obtaining supplies of any kind in Britain.

Prerequisites are complete air supremacy, adequate artillery in the Straits of Dover, and protective mine fields. The time of year is very important, since in the second half of September the weather in the Channel and the North Sea is very bad, and the fogs set in around the middle of October. Since the cooperation of the Air Force is decisive, this must be given greatest consideration in fixing the date.

The following must be established:

1. How long does the Navy require for its technical preparations?

2. How soon can the guns be in place?

3. To what extent can the Navy safeguard the crossing?
