The general plan of campaign was naturally in the hands of General Joffre, since he was in command of far the greater portion of the Allied Force. It has been admitted in France that the original dispositions might be open to criticism, since a number of the French troops had engaged themselves in Alsace and Lorraine, to the weakening of the line of battle in the north, where the fate of Paris was to be decided. It is small profit to a nation to injure its rival ever so grievously in the toe when it is itself in imminent danger of being stabbed to the heart. A further change in plan had been caused by the intense sympathy felt both by the French and the British for the gallant Belgians, who had done so much and gained so many valuable days for the Allies. It was felt that it would be unchivalrous not to advance and do what was possible to relieve the intolerable pressure which was crushing them. It was resolved, therefore, to abandon the plan which had been formed, by which the Germans should be led as far as possible from their base, and to attack them at once. For this purpose the French Army changed its whole dispositions, which had been formed on the idea of an attack from the east, and advanced over the Belgian frontier, getting into touch with the enemy at Namur and Charleroi, so as to secure the passages of the Sambre. It was in fulfilling its part as the left of the Allied line that on August 18 and 19 the British troops began to move northwards into Belgium. The First Army Corps advanced through Le Nouvion, St. Remy, and Maubeuge to Rouveroy, which is a village upon the Mons-Chimay road. There it linked on to the right of the Second Corps, which had moved up to the line of {58} the Condé-Mons Canal. On the morning of Sunday, August 23, all these troops were in position. The 5th Brigade of Cavalry (Chetwode's) lay out upon the right front at Binche, but the remainder of the cavalry was brought to a point about five miles behind the centre of the line, so as to be able to reinforce either flank. The first blood of the land campaign had been drawn upon August 22 outside Soignies, when a reconnoitring squadron of the 4th Dragoon Guards under Captain Hornby charged and overthrew a body of the 4th German Cuirassiers, bringing back some prisoners. The 20th Hussars had enjoyed a similar experience. It was a small but happy omen. [Sidenote: The advance to Mons.]
