The two airships circled slowly over Gosport and Portsmouth, dropping their torpedoes wherever a worthy mark presented itself. The first one discharged from the Flying Fish fell on the deck of the old Victory. The deck burst up, as though all the powder she had carried at Trafalgar had exploded beneath it, and the next moment she broke out in inextinguishable flames. The old Resolution met the same fate from the See Adler, and then the pitiless hail of destruction fell on the docks and jetties. In a few minutes the harbour was ringed with flame. Portsmouth Station, built almost entirely of wood, blazed up like matchwood; then came the turn of the dockyards at Portsea, which were soon ablaze from end to end.

Then the two airships spread their wings like destroying angels over Portsmouth town. Half a dozen torpedoes wrecked the Town Hall and set the ruins on fire. This was the work of the See Adler. The Flying Fish devoted her attention to the naval and military barracks, the Naval College and the Gunnery School on Whale Island. As soon as these were reduced to burning ruins, the two airships scattered their torpedoes indiscriminately over churches, shops and houses, and in the streets crowded by terrified mobs of soldiers, sailors and civilians.

The effect of the torpedoes in the streets was too appalling for description. Everyone within ten or a dozen yards of the focus of the explosion was literally blown to atoms, and for fifty yards round every living creature dropped dead, killed either by the force of the concussion or the poisonous gases which were liberated by the explosion. Hundreds fell thus without the mark of a wound, and when some of their bodies were examined afterwards, it was found that their hearts were split open as cleanly as though they had been divided with a razor, just as are the hearts of fishes which have been killed with dynamite.

John Castellan and his lieutenant, M'Carthy, for the time being gloried in the work of destruction. Captain Frenkel was a soldier and a gentleman, and he saw nothing in it save wanton killing of defenceless people and a wicked waste of ammunition; but the terrible War Lord of Germany had given Castellan supreme command, and to disobey meant degradation, and possibly death, and so the See Adler perforce took her share in the tragedy.

In a couple of hours Portsmouth, Gosport and Portsea had ceased to be towns. They were only areas of flaming ruins; but at last the ammunition gave out, and Castellan was compelled to signal the See Adler to shape her course for Bracklesham Bay in order to replenish the magazines. They reached the bay, and descended at the spot where the Leger ought to have been at anchor. She was not there, for the sufficient reason that the Ithuriel's ram had sent her to the bottom of the Channel.

For half an hour the Flying Fish and the See Adler hunted over the narrow waters, but neither was the Leger nor any other craft to be seen between the Selsey coast and the Isle of Wight. When they came together again in Bracklesham Bay, John Castellan's rage against the hated Saxon had very considerably cooled. Evidently something serious had happened, and something that he knew nothing about, and now that the excitement of destruction had died away, he remembered more than one thing which he ought to have thought of before.

The two rushes of the torpedo boats, supported by the swift cruisers, had not taken place. Not a hostile vessel had entered either Spithead or the Solent, and the British cruisers, which he had been ordered to spare, had got away untouched. It was perfectly evident that some disaster had befallen the expedition, and that the Leger had been involved in it. In spite of the terrible destruction that the Flying Fish, the See Adler and the Banshee had wrought on sea and land, it was plain that the first part of the invader's programme had been brought to nothing by some unknown agency.

He was, of course, aware of the general plan of attack. He had destroyed the battleships of the Fleet Reserve. While he was doing that the destroyers should have been busy among the cruisers, and then the main force, under Admiral Durenne, would follow, and take possession of Southampton, Portsmouth and the Isle of Wight. A detachment of cruisers and destroyers was then to be despatched to Littlehampton, and land a sufficient force to seize and hold the railway at Ford and Arundel, so that the coast line of the L.B.S.C.R., as well as the main line to Horsham and London, should be at the command of the invaders.

Littlehampton was also particularly valuable on account of its tidal river and harbour, which would give shelter and protection to a couple of hundred torpedo boats and destroyers, and its wharves from which transports could easily coal. It is hardly worth while to add that it had been left entirely undefended. It had been proposed to mount a couple of 9.2 guns on the old fort on the west side of the river mouth, with half a dozen twelve-pound quick-firers at the Coast-Guard station on the east side to repel torpedo attack, but the War Office had laughed at the idea of an enemy getting within gunshot of the inviolate English shore, and so one of the most vulnerable points on the south coast had been left undefended.

What would Castellan have given now for the torpedoes which the two ships had wasted in the wanton destruction of Portsmouth, and the murder of its helpless citizens. The main French Fleet by this time could not be very far off. Behind it, somewhere, was the British Channel Fleet, the most powerful sea force that had ever ridden the subject waves, and here he was without a torpedo on either of his ships, and no supplies nearer than Kiel. The Leger had carried two thousand torpedoes and five hundred cylinders of the gases which supplied the motive power. She was gone, and for all offensive purposes the Flying Fish and See Adler were as harmless as a couple of balloons.
