The Duke of York separated his force from that of Coburg just before the middle of August; besides the British, who were not quite 7,000 strong, 11,000 Austrians, over 10,000 Hanoverians and 7,000 Hessians were under his command. The total force, therefore, was nearly 37,000 strong. No one could imagine that, opposed by such troops as the French were able to put into line, and marching against such wretched defences as those of Dunquerque then were, the Duke’s army had not a perfectly easy task before it; and the plan, which was to take Dunquerque and upon the return to join the Austrian march on Paris, was reasonable and feasible. It is important that the reader should firmly seize this and not read history backward from future events. Certain faults are to be observed in the first conduct of the march. It began on the 15th of August, proceeding from Marchiennes to Menin, and at the outset displayed that deplorable lack of marching power which the Duke of York’s command had shown throughout the campaign.[6] From Marchiennes to Tourcoing is a long day’s march: it took the Duke of York four days; and, take the march altogether, nine days were spent in covering less than forty miles. In the course of that march, the British troops had an opportunity of learning to despise their adversary: they found at Linselles, upon the flank of their advance, a number of undisciplined boys who broke the moment the Guards were upon them, and whose physical condition excited the ridicule of their assailants. The army proceeded after this purposeless and unfruitful skirmish to the neighbourhood of the sea coast, and the siege of Dunquerque was undertaken under conditions which will be clear to the reader from the following sketch map. [Illustration: Operations round Dunquerque. September 1793.] The date of the 20th of August must first be fixed in the mind: on that date the army which was to take Dunquerque was separated into its two component parts. The first, under the Duke of York, was to attack the town itself; the second, under the aged Austrian general, Freytag, was to watch the movement of any approaching enemy and to cover the force which was besieging the town. Two days later, the Duke of York was leaving Furnes, which he had made his base for the advance, and Freytag had with the greatest ease brushed the French posts--mainly of volunteers--from before him, and was beginning to take up the flanking positions south and east of Bergues which covered the siege of Dunquerque.
