When Captain Adolph Frenkel, who was in command of the See Adler, saw the column of warships twining and wriggling its way out through the Channel, each ship handled with consummate skill and keeping its position exactly, he could not repress an admiring "Ach!" Still it was not his business to admire, but destroy.

He rose to a thousand feet, swung round to the north-eastward until the whole line had passed beneath him, and then quickened up and dropped to seven hundred feet, swung round again and crept up over the Hogue, which was bringing up the rear. When he was just over her fore part, he let go a shell, which dropped between the conning-tower and the forward barbette.

The navigating bridge vanished; the twelve-inch armoured conning-tower cracked like an eggshell; the barbette collapsed like the crust of a loaf, and the big 9.2 gun lurched backwards and lay with its muzzle staring helplessly at the clouds. The deck crumpled up as though it had been burnt parchment, and the ammunition for the 9.2 and the forward six-inch guns which had been placed ready for action exploded, blowing the whole of the upper forepart of the vessel into scrap-iron.

But an even worse disaster than this was to befall the great twelve-thousand-ton cruiser. Her steering gear was, of course, shattered. Uncontrolled and uncontrollable, she swung swiftly round to starboard, struck a mine, and inside three minutes she was lying on the mud.

Almost at the moment of the first explosion, the beams of twenty searchlights leapt up into the air, and in the midst of the broad white glare hundreds of keen angry eyes saw a winged shape darting up into the air, heading southward as though it would cross the Isle of Wight over Yarmouth. Almost simultaneously, every gun from the tops of the battleships spoke, and a storm of shells rent the air.

But Captain Frenkel had already seen his mistake. The See Adler's wings were inclined at an angle of twenty degrees, her propellers were revolving at their utmost velocity, and at a speed of nearly a hundred miles an hour, she took the Isle of Wight in a leap. She slowed down rapidly over Freshwater Bay. Captain Frenkel took a careful observation of the position and course of the squadron, dropped into the water, folded his wings and crept round the Needles with his conning-tower just awash, and lay in wait for his prey about two miles off the Needles.

The huge black hull of the Irresistible was only a couple of hundred yards away. He instantly sank and turned on his water-ray. As the flagship passed within forty yards he let go his first torpedo. It hit her sternpost, smashed her rudder and propellers, and tore a great hole in her run. The steel monster stopped, shuddered, and slid sternward with her mighty ram high in the air into the depths of the smooth grey sea.

There is no need to repeat the ghastly story which has already been told—the story of the swift and pitiless destruction of these miracles of human skill, huge in size and mighty in armament and manned by the bravest men on land or sea, by a foe puny in size but of awful potentiality. It was a fight, if fight it could be called, between the visible and the invisible, and it could only have one end. Battleship after battleship received her death-wound, and went down without being able to fire a shot in defence, until the Magnificent, smitten in the side under her boilers, blew up and sank amidst a cloud of steam and foam, and the Western Squadron had met the fate of the Eastern.

While this tragedy was being enacted, the cruisers scattered in all directions and headed for the open at their highest speed. It was a bitter necessity, and it was bitterly felt by every man and boy on board them; but the captains knew that to stop and attempt the rescue of even some of their comrades meant losing the ships which it was their duty at all costs to preserve, and so they took the only possible chance to escape from this terrible unseen foe which struck out of the silence and the darkness with such awful effect.

But despite the tremendous disaster which had befallen the Reserve Fleet, the work of death and destruction was by no means all on one side. When he sank the Leger, Erskine had done a great deal more damage to the enemy than he knew, for she had been sent not for fighting purposes, but as a dépôt ship for the Flying Fishes, from which they could renew their torpedoes and the gas cylinders which furnished their driving power. Being a light craft, she was to take up an agreed position off Bracklesham Bay three miles to the north-west of Selsey Bill, the loneliest and shallowest part of the coast, with all lights out, ready to supply all that was wanted or to make any repairs that might be necessary. Her sinking, therefore, deprived John Castellan's craft of their base.
