But as he tells us in his reminiscences, "Fifty Years in the Royal Navy," from the very outset of his endeavours he was hopelessly handicapped; for, whereas "General Gallieni, who was in charge of the defence of Paris, had for the protection of his forty-nine square miles of city two hundred and fifteen guns, and was gradually increasing this number to three hundred; whereas, too, he had plenty of men trained in night flying, and well-lighted aerodromes, he (Sir Percy Scott) had eight guns to defend our seven hundred square miles of the metropolitan area, no trained airmen, and no lighted-up aerodromes."
The amazing part of the whole business was, as Sir Percy Scott explains, and not without a touch of humour, the "War Office was as certain that a Zeppelin could not come to London as the Admiralty was that a submarine could not sink a ship"; hence the corollary that "London's defence was a kind of 'extra turn.'"
Nothing daunted, however, and fully determined that London should be made to wake up to the dangers she was running, he succeeded in spite of all difficulties, and after procuring suitable ammunition, in increasing the number of his guns from the initial eight to one hundred and twelve.
Herein it was that the locomotive shops at Crewe were once again called into requisition, for, as Sir Percy Scott tells us, "unfortunately mountings had to be made for these (guns)," mountings such as base rings, pedestals, pedestal pivots, as well as elevating arcs, sighting arms, etc., the manufacture of which necessarily "took a considerable time," but which were successfully evolved with a minimum of delay at Crewe.
Then again, "the few guns we had for the defence of London were mounted permanently in positions probably as well known to the Germans as to ourselves. We had no efficient guns mounted on mobile carriages which could be moved about and brought into action where necessary."
Being anxious to secure from the French authorities the loan, as a model, of one of their 75-millimetre guns, which as he knew were mounted on motor lorries, and in order to circumvent "Admiralty red-tape methods," Sir Percy Scott promptly took the law into his own hands, and very quickly obtained what he wanted. Owing, however, to the impracticability of adapting the British 3-inch gun to the French lorry mounting, a new design was got out, the gun platform being mounted on a single pair of wheels, which, with the axle, was detachable when the gun came into action, and of which component parts, such as plates, pivots, blocks, covers, catches, limber connections, were forthcoming from Crewe.
Thanks once again to the courtesy of General Gallieni, who agreed to supply "thirty-four of the famous French 75-millimetre guns and twenty thousand shells with fuses complete," Sir Percy Scott finally had at his disposal a total of one hundred and fifty-two guns, which, although admittedly "rather a mixed lot," combined to frustrate the designs of those "airy devils" which so frequently were wont to—
"hover in the sky and pour down mischief."
As time went on, however, and when, notwithstanding the constant alertness of our gunners and the shoals of "archies" spat heavenwards in search of these enemy marauders, the persistency of the latter showed little if any sign of abatement, the idea of retaliation, or the practice of paying the enemy back in his own coin, was mooted as likely to prove the most effective method of clipping his wings, and in spite of protests from that misguided section of the community, aptly designated the "don't-hurt-poor-Germany-brigade," the clamour for retaliation, emanating from an already-too-long-suffering public became so insistent that orders were at length placed for a supply of that special form of "mischief," or medicine, known as aerial bombs, in the manufacture of which, both petrol-incendiary and high-explosive, Crewe Works was requested to assist, and which our gallant airmen were commissioned to "pour down" on fortified positions on the further side of the Hindenburg Line.
How efficacious were deemed to be the ingredients of this medicine may be gathered from the fact that in the autumn of 1917 the chief mechanical engineers of the great railway companies assembled in conclave at the request of the Air Board, and expressed their willingness to co-operate in the manufacture of aeroplanes of the bombing order. Owing, however, to the special conditions applying to the aeroplane industry, and to the fact that those responsible for the administration of our Air-policy decided, after mature consideration, that the scope for producing these machines was actually sufficient for dealing with every emergency, this additional strain was not imposed on the already heavily taxed capacity of the various locomotive workshops after all. Crewe, nevertheless, was not to be gainsaid the privilege of undertaking at least some share in the production of our heavier-than-air machines, and in the tinsmiths' and fitting shops respectively were turned out hundreds of tiny metal pressings or discs, and knuckle joints, essential for the piecing together of the wood fuselage, and on the quality of which depended so largely the lives of our pilots, to whose intrepid instinct undoubtedly "one crowded hour of glorious life" seemed at all times "worth an age without a name," but who nevertheless had no particular wish to come to grief owing to faulty material.
