War with Great Britain and France!
On November 15, 1939, radio intelligence reports have provided the following information on the whereabouts of the British battle fleet:
1) battleships and battlecruisers and various aircraft carriers are not in territorial waters, but in special operations.
2) Most of the remaining battleships apparently mainly use the Firth of Clyde as anchorage.
The U-boats cannot attack the anchorages themselves, but it would be quite possible for the subs to penetrate the widest part of the Firth, right up to the boom. This operation must be carried out as soon as possible. There is a good chance of catching large warships. However, it will be necessary to use mines with a higher explosive effect than TMBs, as they cannot be guaranteed to sink if placed at this depth.
The operation of many submarines against the Home Fleet in the Firth of Clyde will therefore only be worthwhile if carried out in cooperation with own surface forces.
