When the fleet had been in the air about an hour these ten aerostats had so distributed themselves that each of them, with a little manœuvring, could get within bowshot of two others. They also rose a little higher than the rest. The flutter of a white handkerchief was the signal agreed upon, and when this was given by the man in command of the ten, each of them suddenly put on speed, and ran up close to her nearest neighbour. A flight of arrows was discharged at the gas-holder, and then she headed away for the next nearest, and discharged a flight at her.
Considering the apparent insignificance of the means employed, the effects were absolutely miraculous. The explosion of the fulminate on striking either the hard cordage of the net or one of the steel ribs used to give the gas-holder rigidity, broke the two tubes full of liquid. Then came another far more violent explosion, which tore great rents in the envelope. The imprisoned gas rushed out in torrents, and the crippled balloons began to sink, at first slowly, and then more and more rapidly, till the cars, weighted with crews, machinery, and explosives, struck the earth with a crash, and exploded, like so many huge shells, amidst the dense columns of the advancing army corps. In fifteen minutes each of the ten captured aerostats had sent two others to the earth, and then, completely masters of the position, those in charge of them began their assault on the helpless masses below them. This was kept up until the Federation troops appeared. Then they retired to the rear of the French and Italian columns, and devoted themselves to burning their stores and blowing up their ammunition trains with fire-shell.
Assailed thus in front and rear, and demoralised by the defection of the thousands who, as soon as the battle became general, showed the red ribbon and echoed the fierce battle-cry of the Federation, the splendid force sent out by General le Gallifet was practically annihilated by midnight, and by daybreak the Federationists, after fifteen hours of almost continuous fighting, had stormed all the outer positions held by the French and Italians to the south of London, the batteries of which had already been destroyed by the air-ships.
Thus, when the Ithuriel passed over London on the morning of the 7th the position of affairs was as follows: The two armies which had been detached by the Tsar and General le Gallifet to stop the advance of the Federationists had been destroyed almost to a man. Of the two fleets of war-balloons there remained twenty-two aerostats in the hands of the Terrorists, while the twenty-five sent by the Tsar against the air-ships had retired at nightfall to the depot at Muswell Hill to replenish their stock of fuel and explosives. Their ammunition-tenders, slow and unwieldy machines, adapted only for carrying large cargoes of shells, had been rammed and destroyed with ease by the air-ships during the running, or rather flying, fight of the previous afternoon.
At sunset on the 6th the whole available forces of the League which could be spared from the defence of the positions, numbering more than three million men, had descended to the assault on London at nearly fifty different points.
No human words could convey any adequate conception of that night of carnage and terror. The assailants were allowed to advance far into the mighty maze of streets and byways with so little resistance, that they began to think that the great city would fall an easy prey to them after all. But as they approached the main arteries of central London they came suddenly upon barricades so skilfully disposed that it was impossible to advance without storming them, and from which, as they approached them, burst out tempests of rifle and machine gunfire, under which the heads of their columns melted away faster than they advanced.
Light, quick-firing guns, posted on the roofs of lofty buildings, rained death and mutilation upon them. The air-ships, flying hither and thither a few hundred feet above the house-tops, like spirits of destruction, sent their shells into their crowded masses and wrought the most awful havoc of all with their frightful explosives, blowing hundreds of men to indistinguishable fragments at every shot, while from the windows of every house that was not in ruins came a ceaseless hail of missiles from every kind of firearm, from a magazine rifle to a shot-gun.
When morning came the Great Eastern Railway and the Thames had been cleared and opened, and the hearts of the starving citizens were gladdened by the welcome spectacle of train after train pouring in laden with provisions from Harwich, and of a fleet of steamers, flying the Federation flag, which filled the Thames below London Bridge, and was rapidly discharging its cargoes of food at the wharves and into lighters.
As fast as the food could be unloaded it was distributed first to the troops manning the barricades, and then to the markets and shops, whence it was supplied free in the poorer districts, and at the usual prices in the richer ones. All that day London feasted and made merry, for now the Thames was open there seemed to be no end to the food that was being poured into the city which twelve hours before had eaten its last scanty provisions. As soon as one vessel was discharged another took its place, and opened its hold filled with the necessaries and some of the luxuries of life.
The frightful butcheries at the barricades had stopped for the time being from sheer exhaustion on both sides. One cannot fight without food, and the defenders were half-starved when they began. Rage and the longing for revenge had lent them strength for the moment, but twelve hours of incessant street fighting, the most wearing of all forms of battle, had exhausted them, and they were heartily glad of the tacit truce which gave them time to eat and drink.
