ОглавлениеThere is magic in salt water which transmogrifies all things it touches. The aeroplane with its cubist outline undergoes a sea change on reaching the coast and becomes a flying-boat, a thing of beauty, a Viking dragon ship, a shape born of the sea and air with pleasant and easy lines, and in the sun, the dull war-paint stripped from the natural mahogany, a flashing golden craft of enchantment.
During the war nothing was published about the flying-boats, partly because they worked with the Silent Navy, and partly because they were produced in the service. They were created to harry and destroy the German submarines, and were a manifestation of the genius of the English-speaking peoples for all things connected with the sea.
There is a tang of salt in the adventures of the men who boomed out in them over the narrow waters, for they had to do with submarines and ships, and all that that implies. In their job o' work of bombing U-boats, attacking Zeppelins, fighting enemy seaplanes, and carrying out reconnaissance and convoy duties, there is as much romance as in any particular effort in the war. In the future, grown great in size, the boats will form the winged Navy, and will carry mails and passengers over the water-routes of all the world.
Boat seaplanes, or flying-boats as they are called by the men who use them, are a true type of aircraft designed for dealing with the chances and hazards of flying over the sea. They have a stout wooden boat hull, planked with mahogany and cedar, to which the wings, with the engines between the planes, are attached. They carried a service crew of four: Captain, navigator, wireless operator, and engineer. Float seaplanes, which the boats superseded, were practically land machines with two wooden floats instead of wheels, and struck you as being aeroplanes on a visit to the seaside which had put on huge goloshes in order to keep dry. On seeing one pass overhead it was usual to say: "There she goes with her big boots on."
Float seaplanes were not very seaworthy, breaking up quickly in rough water; and many a brave lad, down at sea in them with engine trouble, has been drowned. They are very much to-day what they were in 1914.
From the very beginning of things there was much faith shown by the sea-going pilots of the Royal Naval Air Service in the seaplane as a weapon to do down the U-boat. But the technical people of the service neglected float seaplanes; and flying-boats, of which they did not approve, took a long time to develop. Instead of perfecting seaplanes the slide-rule merchants developed scout land machines with the idea of using them off the decks of ships, and a strong force of aeroplane pilots was collected and provided with fast and handy aeroplanes. The Navy was not ready to use this force, only being converted to its value in 1918, and it was sent to assist the Royal Flying Corps, when the latter was in difficulties in France owing to the lack of pilots and efficient machines. Unfortunately this effort turned a great deal of the energy of the R.N.A.S. away from seaplanes and anti-submarine work.
There would probably not have been any big British flying-boats but for the vision, persistence, and energy, in the face of disbelief and discouragement, of Colonel J. C. Porte, C.M.G., who designed and built at Felixstowe Air Station the experimental machine of each type of British flying-boat successfully used in the service. His boats were very large, the types used in the war weighing from four and a half to six and a half tons, and carried sufficient petrol for work far out from land and big enough bombs to damage or destroy a submarine other than by a direct hit. The pilots were out in the bow of the boat, with the engines behind them, and so had a clear view downward and forward. The boats were very seaworthy, and no lives were lost in operations from England owing to unseaworthiness.

In designing and perfecting flying-boats there were more difficulties than in producing float seaplanes, for the technical problems were great, while engines of sufficient horse-power were not to be had in the early part of the war, and indifference and scepticism had to be overcome. It was not until the spring of 1917 that suitable flying-boats were in being. But this was in time for them to meet the big German submarine effort, when the great yards at Weser, Danzig, Hamburg, Vagesack, Kiel, and Bremen, working day and night, with production driven to its highest pitch by standardisation, were pouring out into the North Sea an incredible number of U-boats.
During this year—a year when it looked as though the Under-sea boats would strangle our merchant shipping and the danger was greater to England than her people realised—forty flying-boats were put into commission, and sighted sixty-eight enemy submarines and bombed forty-four of them.
A submarine is a steel boat shaped something like a cigar. When on the surface it is driven by two petrol engines. Under the surface it is driven by two electric motors, the electricity being obtained from storage batteries. At the bow and stern are horizontal rudders known as hydroplanes. Under ordinary circumstances, when the submarine is about to dive, water is let into tanks until the boat is just floating on the surface with only the conning-tower showing. The petrol engines are stopped and the electric motors are started. Then the hydroplanes are turned down and they force the submarine under the water. The submarine uses its power of travelling under the water to stalk its prey and to hide from its enemies.
When the intensive German submarine campaign began, the methods of hunting U-boats from surface ships had not been perfected. The hydrophone was crude, the technique of using depth charges was not perfected, and the mines and nets were not adequate. Also, the Dover barrage was not then in being. So Fritz, as the service called the Hun submarine, went south—about from his bases to his hunting-grounds.
Picture the sinister grey steel tubes dropping away from the dock in the German harbour as the Commander in the conning-tower gave the order to cast off, the swirl of water at the stern as the twin propellers took up their job, and the gay flutter of signal flags hoisted to the collapsible mast as they passed out of the harbour—a harbour which they would not see, if all went well with them, for from fifteen to twenty-five days, and which, if things went well for the Allies, they would never see again. Once outside the harbour, the Commander would order the engines whacked up to the economical cruising speed of eight to nine knots, a speed at which he could do about two hundred miles a day, and would then turn south, and so proceed on the surface through the North Sea to the Straits of Dover.
Passing through the Straits, either at night on the surface or in the daytime under the water, the Commander would pass down the south coast of England and cruise on the surface in the chops of the English Channel or off the approaches to Ireland. Here he would meet our merchant ships coming in with food, raw material, munitions, and passengers, and either sink them by gun-fire or by torpedo. The attack would be made without warning. Sometimes survivors, who had got away in boats from the doomed vessel, would be shelled. And once the survivors were taken on the deck of a submarine, their life-belts removed, and then the submarine submerged, leaving the unfortunates to drown.
On their run through the North Sea the submarines passed between the Hook of Holland and Harwich Harbour, the distance between the two places being one hundred miles.
Harwich Harbour is a sheltered stretch of water on the East Coast made by the rivers Stour and Orwell emptying into the southern portion of the North Sea. It was the centre of intense anti-Hun activity. It was here that Rear-Admiral Tyrwhitt had his "hot-stuff" destroyer flotilla, that the hydrophone for detecting enemy submarines under the surface of the sea was evolved, that our own submarines which operated in the Bight of Heligoland had their base, and where the flying-boat station of Felixstowe was situated. And it was at Felixstowe that the service experimental flying-boats were designed and built, and a flying-boat squadron operated. During 1917 this squadron, which used an average of only eight boats a month, sighted forty-seven enemy submarines and bombed twenty-five, besides destroying enemy seaplanes and bringing down a Zeppelin in flames.

It was my good fortune to be posted to Felixstowe Air Station in March 1917 and to be put in charge of the flying-boat operations. So this is a yarn about the beginnings and work of a single flying-boat station, but it is characteristic of the work carried out at the seaplane stations strung along the South and East Coasts of Great Britain, from the Scilly Islands, off Land's End, to the Orkneys and Shetlands, off the north of Scotland. If the names and deeds of the pilots at Felixstowe are alone recorded, it is not that equally gallant and skilful men were not harrying the Hun elsewhere, but that their adventures would fill many volumes.
