Secondly, as the Committee supplied the necessary initiative, Carnot supplied the necessary personality of war. His own will and own brain could come to one decision in one moment, and did so. It was he, as we shall see, who won the critical action. He chose Jourdan, a man whose quaint military career we must reluctantly leave aside in so brief a study as this, but at any rate an amateur, and put him in Houchard’s command over the Army of the Northern Frontier, and that command was extended from right away beyond the Ardennes to the sea. He ordered (and Jourdan obeyed) the concentration of men from all down that lengthy line to the right and the left upon one point, Guise. To leave the rest of the frontier weak was a grave risk only to be excused by very rapid action and success: both these were to follow. The concentration was effected in four days. Troops from the extreme north could not come in time. The furthest called upon were beyond Arras, with sixty-five miles of route between them and Guise. This division (which shall be typical of many), not quite eight thousand strong, left on receiving orders in the morning of the 3rd of October and entered Guise in the course of the 6th. The rate of marching and the synchrony of these movements of imperfect troops should especially be noted by any one who would understand how the Revolution succeeded. [Illustration: The rapid eight days’ concentration in front of Maubeuge. October 1783.] A second division of over thirteen thousand men followed along the parallel road, with a similar time table. From the other end of his line, a detachment under Beauregard, just over four thousand men, was called up from the extreme right. It will serve as a typical example upon the eastern side of this lightning concentration. It had been gathered near Carignan, a town full fourteen miles beyond Sedan. It picked up reinforcements on the way and marched into Fourmies upon the 11th, after covering just seventy miles in the three and a half days. With its arrival the concentration was complete, and not a moment too soon, for the bombardment of Maubeuge was about to begin. From the 11th to the 15th of October the army was advanced and drawn up in line, a day’s march in front of Guise, with its centre at Avesnes and facing the covering army of Coburg, which lay entrenched upon a long wooded crest with the valley of the Sambre upon its right and the village of Wattignies, on a sort of promontory of high land, upon its left. The Austrian position was reconnoitred upon the 14th. Upon the 15th the general attack was delivered and badly repelled. When darkness fell upon that day few in the army could have believed that Maubeuge was succourable--and it was a question of hours.
