"We saw how Inchkeith Fort had been silenced, and how our Volunteer batteries had been destroyed, and knew that sooner or later we must share the same fate, and abandon our position. As boatload after boatload of Russians attempted to land, we either sank them by shots from our guns or swept them with a salvo of bullets from our Maxims; yet as soon as we had hurled back one landing party others took its place.
"Many were the heroic deeds our gunners performed that night, as hand to hand they fought, and annihilated the Russians who succeeded in landing; but in this frightful struggle we lost heavily, and at length, when all hope of an effective defence had been abandoned, we placed electric wires in the magazine, and the order was given to retire. This we did, leaving our search-light in position in order to deceive the enemy.
"Half our number had been killed, and we sped across to Bonnington, running out a wire along the ground as we went. The Russians, now landing rapidly in great force, swarmed into the fort and captured the guns and ammunition, while a party of infantry pursued us. But we kept them back for fully a quarter of an hour, until we knew that the fort would be well garrisoned by the invaders; then we sent a current through the wire.
"The explosion that ensued was deafening, and its effect appalling. Never have I witnessed a more awful sight. Hundreds of tons of all sorts of explosives and ammunition were fired simultaneously by the electric spark, and the whole fort, with nearly six hundred of the enemy, who were busy establishing their headquarters, were in an instant blown into the air. For several moments the space around us where we stood seemed filled with flying débris, and the mangled remains of those who a second before had been elated beyond measure by their success.
"Those were terribly exciting moments, and for a few seconds there was a cessation of the firing. Quickly, however, the bombardment was resumed, and although we totally annihilated the force pursuing us, we fell back to Restalrig, and at length gained the battery that had been established on Arthur's Seat, and which was now keeping up a heavy fire upon the Russian transports lying out in the Narrow Deep. Subsequently we went on to Dalkeith. Our situation is most critical in every respect, but we are expecting reinforcements, and a terrible battle is imminent."
Thus the Russians landed three corps of 20,000 each where they were least expected, and at once prepared to invest Edinburgh and Glasgow. Three of the boats which came ashore at Leith that night, after the blowing up of the fort, brought several large mysterious-looking black boxes, which were handled with infinite care by the specially selected detachment of men who had been told off to take charge of them. Upon the locks were the official seals of the Russian War Office; and even the men themselves, unaware of their contents, looked upon them with a certain amount of suspicion, handling them very gingerly, and placing them in waggons which they seized from a builder's yard on the outskirts of the town.
The officers alone knew the character of these mysterious consignments, and as they superintended the landing, whispered together excitedly. The news of the invasion, already telegraphed throughout Scotland from end to end, caused the utmost alarm; but had the people known what those black boxes, the secret of which was so carefully guarded, contained, they would have been dismayed and appalled.
Truth to tell, the Russians were about to try a method of wholesale and awful destruction, which, although vaguely suggested in time of peace, had never yet been tested in the field.
If successful, they knew it would cause death and desolation over an inconceivably wide area, and prove at once a most extraordinary and startling development of modern warfare. The faces of a whole army, however brave, would blanch before its terrific power, and war in every branch, on land and on sea, would become revolutionised.
