The air would be charged with death. Beneath the laughing waves great battleships would be speeding swiftly, silently, and invisibly on their errands of destruction, and the fair face of earth would be scarred by the harrow of battle, and seared with the fires of murderous passion.
The ocean traffic of the world had been almost wholly at a standstill for nearly a month. Transports which could complete their voyages before the end of the truce had done so; but since the 1st of May only short voyages had been attempted, for it was known that escape from the attack of a submarine battleship would be absolutely impossible for any vessels that floated on the surface of the water.
The immediate results of this had of course been the dislocation of trade and commerce and ever-increasing scarcity of food in the great centres of population. Impossible, absurd even, as it still seemed to those who had not thoroughly recognised the tremendous gravity of the situation, the inhabitants of the magnificent cities of the old and new worlds were actually within measurable distance, even before a blow had been struck, of seeing the spectre of Famine cross the threshold of their palaces.
In a few days communications by land would be as difficult and as dangerous as those by sea, for, swift as the trains were, their speed was far excelled by that of the slowest air-ship, which could wreck them with a single shot. Bridges would be destroyed, stations blown up, and lines cut in a hundred places at once, till railway travelling would have to cease all over the world.
Thus the most splendid civilisation of all the ages stood trembling on the verge of destruction at the moment when the sleepless eyes of the inhabitants of Alexandria saw the first faint glow of the dawn brightening the eastern sky. No one knew where or how the first blow would be struck in the strange and terrible warfare for the commencement of which the rising of that morning’s sun gave the signal.
There were scarcely any elements in common with the war of the nineteenth century save the slaughter and destruction that it would entail. There could be no marshalling of fleets or warships on the sea, for to be detected by an enemy would be coming very near to being destroyed. Every blow would have to be struck swiftly, silently, and without warning, for only one could be struck, and to fail would be to be lost.
So, too, in the air, as had been proved at Kerguelen and Mount Terror. Everything would depend upon the supreme strategy which enabled the first fatal shot to be sent home that would decide battle after battle without hope for the vanquished to recover from their defeat.
But after all it would be on land that the terrors of the new warfare would be most fearfully manifested. It needed but little effort of the highly-strung imaginations of those who were waiting for the world-tragedy to begin to picture vast armies, magnificent in their strength and splendid in their equipments, marching to grapple with each other on some field of Titanic strife. Suddenly and without warning they would be smitten by an invisible foe floating far above the clouds, or perhaps visible only as a tiny speck of light high in the central blue.
Their battalions would be torn to pieces, their regiments decimated and thrown into confusion, their commanders—the brains of the huge organisms—would have no such protection as they had in the wars of former times, for the aerial artillery would reach everywhere, and the Commander-in-Chief in his headquarters would be as much exposed as the private in his bivouac.
