THE NIGHT OF TERROR BEGINS—

Denis Castellan had put the situation tersely, but with a considerable amount of accuracy. Earth and sea and sky were ablaze with swarms of shooting, shifting lights, which kept crossing each other and making ever-changing patterns of a magnificent embroidery, and amidst these, huge shells and star-rockets were bursting in clouds of smoke and many-coloured flame. The thunder of the big guns, the grinding rattle of the quick-firers, and the hoarse, whistling shrieks of the shells, completed the awful pandemonium of destruction and death that was raging round Dover.

The truth was that the main naval attack of the Allies was being directed on the south-eastern stronghold. I am aware that this is not the usual plan followed by those who have written romantic forecasts of the invasion of England. It seems at first sight, provided that the enemy could pass the sentinels of the sea unnoticed, easy to land troops on unprotected portions of our shores; but, in actual warfare, this would be the most fatal policy that could be pursued, simply because, whatever the point selected, the invaders would always find themselves between two strong places, with one or more ahead of them. They would thus be outflanked on all sides, with no retreat open but the sea, which is the most easily closed of all retreats.

From their point of view, then, the Allies were perfectly right in their project of reducing the great strongholds of southern and eastern England, before advancing with their concentrated forces upon London. It would, of course, be a costly operation. In fact Britain's long immunity from invasion went far to prove that, to enemies possessing only the ordinary means of warfare, it would have been impossible, but, ever since the success of the experiment at Potsdam, German engineering firms had been working hard under John Castellan's directions turning out improved models of the Flying Fish. The various parts were manufactured at great distances apart, and no one firm knew what the others were doing. It was only when the parts of the vessels and the engines were delivered at the closely-guarded Imperial factory at Potsdam, that, under Castellan's own supervision, they became the terrible fighting machines that they were.

The Aërial Fleet numbered twenty when war broke out, and of these five had been detailed for the attack on Dover. They were in fact the elements which made that attack possible, and, as is already known, four were co-operating with the Northern Division of the Allied Fleets against the forts defending Chatham and London.

Dover was at that time one of the most strongly fortified places in the world. Its magnificent new harbour had been completed, and its fortifications vastly strengthened and re-armed with the new fourteen-inch gun which had superseded the old sixteen-inch gun of position, on account of its greater handiness, combined with greater penetrating power.

But at Dover, as at Portsmouth, the forts were powerless against the assaults of these winged demons of the air. They were able to use their terrible projectiles with reckless profusion, because only twenty-two miles away at Calais there were inexhaustible stores from which they could replenish their magazines. Moreover, the private factory at Kiel, where alone they were allowed to be manufactured, were turning them out by hundreds a day.

They had, of course, formed the vanguard of the attacking force which had advanced in three divisions in column of line abreast from Boulogne, Calais and Antwerp. The Boulogne and Calais divisions were French, and each consisted of six battleships with the usual screens of cruisers, destroyers and torpedo boats: these two divisions constituted the French North Sea Squadron, whose place had been taken by the main German Fleet, assisted by the Belgian and Dutch squadron.

Another German and Russian division was advancing on London. It included four first-class battleships, and two heavily-armed coast defence ships, huge floating fortresses, rather slow in speed, but tremendous in power, which accompanied them for the purpose of battering the fortifications, and doing as much damage to Woolwich and other important places on both sides as their big guns could achieve. Four Flying Fishes accompanied this division.
