No; these things were of no account in his eyes. Ireland must be free, and the girl he had come to love so swiftly, and with such consuming passion, must be his. Nothing else mattered. Was he not Lord of the Air, and should the desire of his heart be denied him?

Thus mused John Castellan in the conning-tower of the Flying Fish, as he circled slowly above the ruins of Dover, while the man who had beaten him in the swimming-race was sitting in the observatory on far-off Whernside, verifying his night's observations and calculating for the hundredth time the moment of the coming of an Invader, compared with which all the armed legions of Europe were of no more importance than a swarm of flies.

When he had satisfied himself that Dover was quite defenceless he sent one of the French Flying Fishes across to Calais with a letter to the District Commander, describing briefly what had taken place, and telling him that it would be now quite safe for the transports to cross the Straits and land the troops at Portsmouth, Newhaven, Folkestone, Dover and Ramsgate.

He would station one of his airships over each of these places to prevent any resistance from land or sea, and would himself make a general reconnaissance of the military dispositions of the defenders. He advised that the three Flying Fishes, which had been reserved for the defence of the Kiel Canal, should be telegraphed for as convoys, as there was now no danger of attack, and that the depot of torpedoes and motive power for his ships should be transferred from Calais to Dover.

As soon as he had despatched this letter, Castellan ordered two of his remaining ships to cruise northward to Ramsgate, keeping mainly along the track of the railway, one on each side of it, and to wreck the first train they saw approaching Dover, Deal, Sandwich and Ramsgate from the north. The other two he ordered to take the Western Coast line as far as Portsmouth, and do the same with trains coming east.

Then he swung the Flying Fish inland, and took a run over Canterbury, Ashford, Maidstone, Tonbridge, Guildford and Winchester, to Southampton and Portsmouth, returning by Chichester, Horsham and Tunbridge Wells.

It was only a tour of observation for the purpose of discovering the main military dispositions of the defenders—who were now concentrating as rapidly as possible upon Folkestone and Dover—but he found time to stop and drop a torpedo or two into each town or fort that he passed over—just leaving cards, as he said to M'Carthy—as a promise of favours to come.

He also wrecked half a dozen long trains, apparently carrying troops, and incidentally caused a very considerable loss of good lives and much confusion, to say nothing of the moral effect which this new and terrible form of attack produced upon the nerves of Mr Thomas Atkins.

When he got back to Dover he found a letter waiting for him from the General informing him that the transports would sail at once, and that his requests would be complied with.
