Objectives.

2.

Ø

It

The main enemy objectives in the initial stages will probably be -

Aerodromes.

Ships at sea and in port.

Communications and facilities for inter-communication. Aircraft Industry, and other Munition Industries. Power Stations.

Actually during an attempt at seaborne invasion, however, the enemy is likely to attempt to isolate the area of his landings, and to prevent the movement of our reserves and supplies to the threatened point, by heavy air lombardment of road and rail communications leading to it.

Attempts will probably be made to lay mines off opera- tional ports and between the areas selected for landing and the flect bases.

Scale of Attack.

3.

It is estimated that under average conditions the Germans could maintain a scale of night attack of the order of 400/500 combers per night.
