"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 s.p.a.ce around us where we stood seemed filled with flying debris, 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 ash.o.r.e 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.

But the boxes remained locked and guarded. The secret was to be kept until the morrow, when the first trial was ordered to be made, and the officers in charge expressed an opinion between themselves that a blow would then be struck that would at once startle and terrify the whole world.

CHAPTER x.x.x.

ATTACK ON EDINBURGH.

In attacking Edinburgh the besiegers at once discovered they had a much more difficult task than they had antic.i.p.ated. The Russian onslaught had been carefully planned. Landing just before dawn, the 1st Corps, consisting of about twenty thousand men, marched direct to Glasgow by way of South Queensferry and Kirkliston, and through Linlithgow, sacking and burning all three towns in the advance.

The 3rd Army Corps succeeded, after some very sharp skirmishing, in occupying the Pentland Hills, in order to protect the flanks of the first force, while a strong detachment was left behind to guard the base at Leith. The 2nd Corps meanwhile marched direct upon Edinburgh.

The defenders, consisting of Militia, Infantry, Artillery, the local Volunteers left behind during the mobilisation, and a large number of civilians from the neighbouring towns, who had hastily armed on hearing the alarming news, were quickly ma.s.sed in three divisions on the Lammermuir Hills, along the hills near Peebles, and on Tinto Hill, near Lanark.

The Russian army corps which marched from Leith upon Edinburgh about seven o'clock on the following morning met with a most desperate resistance. On Arthur's Seat a strong battery had been established by the City of Edinburgh Artillery, under Col. J. F. Mackay, and the 1st Berwickshire, under Col. A. Johnston; and on the higher parts of the Queen's Drive, overlooking the crooked little village of Duddingston, guns of the 1st Forfarshire, under Col. Stewart-Sandeman, V.D., flashed and shed forth torrents of bullets and sh.e.l.l, which played havoc with the enemy's infantry coming up the Portobello and Musselburgh roads.

Batteries on the Braid and Blackford Hills commanded the southern portion of the city; while to the west, the battery on Corstorphine Hill prevented the enemy from pushing along up the high road from Granton.

Between Jock's Lodge and Duddingston Mills the Russians, finding cover, commenced a sharp attack about nine o'clock; but discovering, after an hour's hard fighting, that to attempt to carry the defenders' position was futile, they made a sudden retreat towards Niddry House.

The British commander, observing this, and suspecting their intention to make a circuit and enter the city by way of Newington, immediately set his field telegraph to work, and sent news on to the infantry brigade at Blackford.

This consisted mainly of the Queen's Volunteer Rifle Brigade (Royal Scots), under Col. T. W. Jones, V.D.; the 4th, 5th, 6th, 7th, and 8th Volunteer Battalions of the Royal Scots, under Col. W. U. Martin, V.D., Col. W. I. Macadam, Col. Sir G. D. Clerk, Col. P. Dods, and Col. G. F.

Melville respectively, with a company of engineers. The intelligence they received placed them on the alert, and ere long the enemy extended his flank in an endeavour to enter Newington. The bridges already prepared for demolition by the defenders were now promptly blown up, and in the sharp fight that ensued the enemy were repulsed with heavy loss.

Meanwhile the formidable division of the 3rd Russian Army Corps guarding the base at Leith had attacked the Corstorphine position, finding their headquarters untenable under its fire, and although losing several guns and a large number of men, they succeeded, after about an hour's hard fighting, in storming the hill and sweeping away the small but gallant band of defenders.

The fight was long. It was a struggle to the death. Over the whole historic battle-ground from the Tweed to the Forth, fighting spread, and everywhere the loss of life was terrible.

The long autumn day pa.s.sed slowly, yet hostilities continued as vigorous and sanguinary as they had begun. Before the sun sank many a brave Briton lay dead or dying, but many more Muscovites had been sent to that bourne whence none return.

As it was, the British line of communications was broken between Temple and Eddleston, the outposts at the latter place having been surprised and slaughtered. But although the enemy strove hard to break down the lines of defence and invest Edinburgh, yet time after time they were hurled back with fearful loss. Colinton and Liberton were sacked and burned by the Tsar's forces. On every hand the Russians spread death and destruction; still the defenders held their own, and when the fighting ceased after nightfall Edinburgh was still safe. Strong barricades manned by civilians had been hastily thrown up near the station in Leith Walk, in London Road opposite the Abbey Church, in Inverleith Row, in Clerk Street and Montague Street, while all the bridges over the Water of Leith had been blown up with gun-cotton; quick-firing guns had been posted on Calton Hill and at the Castle, while in St. Andrew's Square a battery had been established by the 1st Haddington Volunteer Artillery, under Major J. J. Kelly, who had arrived in haste from Dunbar, and this excellent position commanded a wide stretch of country away towards Granton.

At dead of night, under the calm, bright stars, a strange scene might have been witnessed. In the deep shadow cast by the wall of an old and tumble-down barn near the cross-roads at Niddry, about three miles from Edinburgh, two Russian infantry officers were in earnest conversation.

They stood leaning upon a broken fence, talking in a half-whisper in French, so that the half-dozen privates might not understand what they said. The six men were busy unpacking several strange black cases, handling the contents with infinite care. Apparently three of the boxes contained a quant.i.ty of fine silk, carefully folded, while another contained a number of square, dark-looking packages, which, when taken out, were packed in order upon a strong net which was first spread upon the gra.s.s. Ropes were strewn over the ground in various directions, the silk was unfolded, and presently, when all the contents had been minutely inspected by the two officers with lanterns, a small tube was taken from a box that had remained undisturbed, and fastened into an object shaped like a bellows.

Then, when all preparations were satisfactorily completed, the six men threw themselves upon the gra.s.s to s.n.a.t.c.h an hour's repose, while the officers returned to their previous positions, leaning against the broken fence, and gravely discussing their proposals for the morrow's gigantic sensation. The elder of the two was explaining to his companion the nature of the _coup_ which they intended to deliver, and the mode in which it would be made. So engrossed were they in the contemplation of the appalling results that would accrue, they did not observe that they were standing beneath a small square hole in the wall of the barn; neither did they notice that from this aperture a dark head protruded for a second and then quick as lightning withdrew. It was only like a shadow, and disappeared instantly!

Ten minutes later a mysterious figure was creeping cautiously along under the hedge of the high road to Newington in the direction of the British lines. Crawling along the gra.s.s, and pausing now and then with his ear to the ground, listening, he advanced by short, silent stages, exercising the greatest caution, well aware that death would be his fate should he be discovered. In wading the Braid Burn he almost betrayed himself to a Russian sentry; but at last, after travelling for over an hour, risking discovery at any moment, he at length pa.s.sed the British outposts beyond Liberton, and ascended the Braid Hills to the headquarters.

The story he told the General commanding was at first looked upon as ludicrous. In the dim candlelight in the General's tent he certainly looked a disreputable derelict, his old and tattered clothes wet through, his hands cut by stones and bleeding, and his face half covered with mud. The three officers who were with the General laughed when he dashed in excitedly, and related the conversation he had overheard; yet when he subsequently went on to describe in detail what he had witnessed, and when they remembered that this tramp was an artilleryman who had long ago been conspicuous by his bravery at El Teb, and an ingenious inventor, their expression of amus.e.m.e.nt gave way to one of alarm.

The General, who had been writing, thoughtfully tapped the little camp table before him with his pen. "So they intend to destroy us and wreck the city by that means, now that their legitimate tactics have failed! I can scarcely credit that such is their intention; yet if they should be successful--if"--

"But they will not be successful, sir. If you will send some one to a.s.sist me, and allow me to act as I think fit, I will frustrate their dastardly design, and the city shall be saved."

"You are at liberty to act as you please. You know their plans, and I have perfect confidence in you, Mackenzie," replied the officer. "Do not, however, mention a word of the enemy's intention to any one. It would terrify the men; and although I do not doubt their bravery, yet the knowledge of such a horrible fate hanging over them must necessarily increase their anxiety, and thus prevent them from doing their best. We are weak, but remember we are all Britons. Now come," he added, "sit there, upon that box, and explain at once what is your scheme of defence against this extraordinary attack."

And the fearless man to whom the General had entrusted the defence of Edinburgh obeyed, and commenced to explain what means he intended to take--a desperate but well-devised plan, which drew forth words of the highest commendation from the commanding officer and those with him.

They knew that the fate of Edinburgh hung in the balance, and that if the city were taken it would be the first step towards their downfall.

CHAPTER x.x.xI.

"THE DEMON OF WAR."

Two hours later, just before the break of day, British bugles sounded, and the camp on the Braid Hills was immediately astir. That the enemy were about to test the efficiency of a new gigantic engine of war was unknown except to the officers and the brave man who had risked his life in order to obtain the secret of the foeman's plans.

To him the British General was trusting, and as with knit brows and anxious face the grey-haired officer stood at the door of his tent gazing across the burn to Blackford Hill, he was wondering whether he had yet obtained his coign of vantage. From the case slung round his shoulder he drew his field gla.s.ses and turned them upon a clump of trees near the top of the hill, straining his eyes to discover any movement.

On the crest of the hill two Volunteer artillery batteries were actively preparing for the coming fray, but as yet it was too dark to discern anything among the distant clump of trees; so, replacing his gla.s.ses, the commanding officer re-entered his tent and bent for a long time over the Ordnance Map under the glimmering, uncertain light of a guttering candle.

Meanwhile the Russians were busily completing their arrangements for striking an appalling blow.

Concealed by a line of trees and a number of farm buildings, the little section of the enemy had worked indefatigably for the past two hours, and now in the grey dawn the contents of the mysterious boxes, a long dark monster, lay upon the gra.s.s, moving restlessly, trying to free itself from its trammels.

It was a huge and curiously-shaped air-ship, and was to be used for dropping great charges of melinite and steel bombs filled with picric acid into the handsome historic city of Edinburgh! Some of the sh.e.l.ls were filled with sulphurous acid, carbon dioxide, and other deadly compounds, the intent being to cause suffocation over wide areas by the volatilisation of liquid gases!

This controllable electric balloon, a perfection of M. Gaston Tissandier's invention a few years before, was, as it lay upon the gra.s.s, nearly inflated and ready to ascend, elongated in form, and filled with hydrogen.

It was about 140 feet long, 63 feet in diameter through the middle, and the envelope was of fine cloth coated with an impermeable varnish. On either side were horizontal shafts of flexible walnut laths, fastened with silk belts along the centre, and over the balloon a netting of ribbons was placed, and to this the car was connected. On each of the four sides was a screw propeller 12 feet in diameter, driven by bichromate of pota.s.sium batteries and a dynamo-electric motor. The propellers were so arranged that the balloon could keep head to a hurricane, and when proceeding with the wind would deviate immediately from its course by the mere pulling of a lever by the aeronaut.

Carefully packed in the car were large numbers of the most powerful infernal machines, ingeniously designed to effect the most awful destruction if hurled into a thickly-populated centre. Piled in the smallest possible compa.s.s were square steel boxes, some filled with melinite, dynamite, and an explosive strongly resembling cordite, only possessing twice its strength, each with fulminating compounds, while others contained picric acid fitted with gla.s.s detonating tubes. Indeed, this gigantic engine, which might totally wreck a city and kill every inhabitant in half an hour while at an alt.i.tude of 6 miles, had rightly been named by the Pole who had perfected Tissandier's invention--"The Demon of War."

While the two officers of the Russian balloon section, both experienced aeronauts, were finally examining minutely every rope, ascertaining that all was ready for the ascent, away on Blackford Hill one man, pale and determined, with coat and vest thrown aside, was preparing a counterblast to the forthcoming attack. Under cover of the clump of trees, but with its muzzle pointing towards Bridgend, a long, thin gun of an altogether strange type had been brought into position. It was about four times the size of a Maxim, which it resembled somewhat in shape, only the barrel was much longer, the store of ammunition being contained in a large steel receptacle at the side, wherein also was some marvellously-contrived mechanism. The six gunners who were a.s.sisting Mackenzie at length completed their work, and the gun having been carefully examined by the gallant man in charge and two of the officers who had been in the tent with the General during the midnight consultation, Mackenzie, with a glance in the yet hazy distance where the enemy had bivouaced, pulled over a small lever, which immediately started a dynamo.
