The Cruiser Admirals however plumped for the Super-Blonde. Meanwhile, between the hammer and the anvil, Sir Philip Watts had scraped together another inch of armour, making 3 inches in all, and Sir Henry Oram guaranteed 30 or even 31 knots of speed.
Now for the guns. The proverbial three alternatives presented themselves. We could have ten 4–inch (32–lb. shell) or five 6–inch (100–lb. shell), or we could compromise on a blend of the two. The Cruiser Admirals’ Committee finally agreed on a compromise. Six 4–inch guns were to be mounted on the superstructure forward and two 6–inch on the main deck aft. It was denied that this arrangement was a compromise. It must be judged in relation to what the ship would have to do. When advancing to attack destroyers she could fire a large number of 32–lb. shots, each sufficient to wound them grievously; when retreating from a larger cruiser she could strike back with her two 6–inch guns. I personally insisted upon the two 6–inch. The Navy would never recognise these vessels as cruisers if they did not carry metal of that weight. The ultimate evolution of this type in subsequent years was to a uniform armament of five 6–inch.
We must now admit that this was right, but they were big guns to put in so small a ship, and many doubted whether the platform would be sufficiently stable. For the value then of the two Dartmouths and one Blonde which had been previously proposed, plus something scraped from other incidentals of the programme, plus a hope that the Chancellor of the Exchequer would not be too severe, we were able to lay down no less than eight of these new vessels. I presented them to Parliament in the following words:—
‘They are described as Light Armoured Cruisers, and they will in fact be the smallest, cheapest and fastest vessels protected by vertical armour ever projected for the British Navy. They are designed for attendance on the Battle Fleet. They are designed to be its eyes and ears by night and day; to watch over it in movement and at rest. They will be strong enough and fast enough to overhaul and cut down any torpedo boat destroyer afloat, and generally they will be available for the purposes of observation and reconnaissance.’
Judged by its popularity in peace and war this type may claim success. In the three programmes of 1912, 1913 and 1914, 8, 8, and 6 of them were built respectively, and after the war began no fewer than 18 more were built. The first eight fired their torpedoes from the deck as if they were destroyers. I put the greatest pressure on the constructors to give them underwater torpedo tubes, but they could not manage it in 1912. In 1913 this had been achieved, and was continued in all other vessels of this class. Such were the advantages of speed in Light Cruisers that not one of these vessels, nor the C Class, nor D Class which were their successors, although frequently engaged with the enemy, was ever sunk by gunfire. The first of these vessels from which the class was named was the Arethusa, and under the broad pennant of Commodore Tyrwhitt she established on an unchallengeable foundation the glories claimed of old for that ship.
Come, all you gallant seamen bold,
Whose hearts are cast in honour’s mould;
I will to you a tale unfold
Of the saucy Arethusa.
Such were the characteristics of the new vessels with which we proceeded to equip the Royal Navy in the programme of 1912.
