Agreeably with the above, instructions must be prepared for the guidance of the Police, Fire Brigade, and civil population under aerial bombardment. This will have to be sustained with composure. Arrangements must be concerted with the Home Office and the Office of Works for the extinction of lights upon a well-conceived plan, for the clearance and illumination in the parks, in order that the defending aeroplanes can have freedom of action, etc. The whole of the points dealt with in this minute are to be elaborated and put into precise detail this afternoon by a Committee composed as follows:— Third Sea Lord (in the Chair). Director of Air Division. Director of Naval Ordnance. And a representative of the War Office from either the Master General of the Ordnance or Home Defence Department. I expect to receive not later than to-morrow a definite programme for action within the lines of this minute. The whole matter is of the highest urgency. _September 5, 1914._ Secretary. First Sea Lord. Director of Air Division. In order to discharge adequately the responsibilities which we have assumed for the aerial defence of England, it is necessary that we should maintain an aerial control over the area approximately 100 miles radius from Dunkirk. To do this, we must support the aeroplanes which are stationed on the French coast with sufficient armed motor cars and personnel to enable advanced subsidiary aeroplane bases to be established 30, 40 and 50 miles inland.
