The needs and activities of the naval aeroplanes in the neighbourhood of Dunkirk led directly to the development of the armoured car, and the armoured car led directly to the birth of the tank, which was in essence only an armoured car capable of crossing trenches. Almost immediately after the German inroad into Belgium, I received accounts of the remarkable work done by a Belgian motor-car, hastily equipped with armour and a machine gun, in shooting down and driving back the numerous Uhlans with which the enemy were seeking to overrun the country. Commander Samson was prompt to realise and seize the advantage of armoured cars for the purpose of protecting his aeroplane operations and also on their own account. In view of the reports received from him and other sources, I gave, during the latter part of August and September, successive orders for the formation of armoured-car squadrons under the Admiralty; and as all this arose out of the aeroplane squadron stationed at Dunkirk, the formation of the armoured-car squadrons was entrusted to Commodore Sueter. In this task this officer displayed great energy, and in a very short time no less than seven or eight squadrons were called into being, based on the purchase of all the Rolls-Royce cars that were available and rapidly improvised armour protection. The first few cars had scarcely begun to show their advantages in Commander Samson’s guerrilla from Dunkirk when the difficulty which ultimately led to the creation of the tank manifested itself. The German cavalry sought to protect themselves against the attack of the armoured cars by digging trenches across the road. To meet this, I gave the following directions:— _September 23, 1914._ Colonel Ollivant. Director of Air Division. Royal Naval Division Administration. It is most important that the motor transport and armed motor-cars should be provided to a certain extent with cars carrying the means of bridging small cuts in the road, and an arrangement of planks capable of bridging a ten- or twelve-feet span quickly and easily should be carried with every ten or twelve machines. A proportion of tools should also be supplied. Let me have proposals at once.[63]
