"Necessary or not," replied Arnold, "it is the Master's orders, and I have only to obey them. This is the day of vengeance for which he has waited so long, and you can hardly expect him to show much mercy. It lies between him and Tremayne. For my part I will stay my hand only when I am ordered to do so. "Still, if any one can influence Natas to mercy, you can. Nothing can now stop the slaughter on the north, I'm afraid, for the Russians are caught in a hopeless trap. The Londoners are enraged beyond control, and if the men spared them I believe the women would tear them to pieces. But there are two or three millions of lives or so to be saved at the south, and perhaps there is still time to do it. It would be a task worthy of the Angel of the Revolution; why should you not try it?" "I will do so," said Natasha, and without another word she turned away and walked quickly towards the entrance to the saloon. CHAPTER XLV. ARMAGEDDON. On the southern side of London the struggle between the Franco-Italian armies and the troops of the Federation had been raging all night with unabated fury along a curved line extending from Bexley to Richmond. The railways communicating with the ports of the south and east had, for their own purposes, been left intact by the commanders of the League; and so sudden and utterly unexpected had been the invasion of the force from America, and the simultaneous uprising of the British Section of the Brotherhood, that they had fallen into the hands of the Federationists almost without a struggle. This had enabled the invaders and their allies to concentrate themselves rapidly along the line of action which had been carefully predetermined upon. Landing almost simultaneously at Southampton, Portsmouth, Shoreham, Newhaven, Hastings, Folkestone, Dover, Deal, Ramsgate, and Margate, they had been joined everywhere by their comrades of the British Section, whose first action, on receiving the signal from the sky, had been to seize the railways and shoot down, without warning or mercy, every soldier of the League who opposed them. What had happened at Harwich had at the same time and in the same fashion happened at Dover and Chatham. The troops in occupation had been caught and crushed at a blow between overwhelming forces in front and rear. Added to this, the International was immensely stronger in France and Italy than in Russia, and therefore the defections from the ranks of the League had been far greater than they had been in the north.
