The Allies lay along the river Scheldt on Friday, the 16th of May: Tournay was their centre, with the Duke of York in command of the chief force there; five or six miles north, down the river, was one extremity of their line at a place called Warcoing: it was a body of Hanoverians. The left, under the Archduke Charles, was Austrian and had reached a place a day’s march south of Tournay called St. Amand. Over against the Allies lay a large French force also occupying a wide front of over fifteen miles, the centre of which was Tourcoing, then a village. Its left was in front of the fortress of Courtrai. Now, behind the French, up country northward in the opposite direction from the line of the Allies on the Scheldt was another force of the Allies under Clerfayt. The plan was that the Allied right should advance on to Mouscron and take it. The Allied centre should advance on to Tourcoing and Mouveaux and take them, while the left should march across the upper waters of the river Marque, forcing the bridges that crossed that marshy stream, and come up alongside the centre. In other words, there was to be an attack all along the French line from the south, and while it was proceeding, Clerfayt, from the north of the French, was to cross the Lys and attack also. On the day of the 17th what happened was this: The left of the Allies, marching from St. Amand, came up half a day late; the right of the Allies took Mouscron, but were beaten out of it by the French. The centre of the Allies fulfilled their programme, reaching Tourcoing and its neighbourhood by noon and holding their positions. It is to the honour of English arms that this success was accomplished by a force a third of which was British and the most notable bayonet work in which was done by the Guards. Meanwhile, Clerfayt was late in moving and in crossing the river Lys, which lay between him and his objective. [Illustration: Tourcoing. May 16 to 18, 1794. The breakdown of the attempt of the Allies to cut off the French near Courtrai from Lille was due to their failure to synchronise They should have been in line from A to B at noon of the 17th with Clerfayt at C.] When night fell, therefore, on the first day of the action, a glance at the map will show that instead of one solid line advancing against the French from A to B, and the northern force in touch with it at C, the Allied formation was an absurd projection in the middle, due to the success of the mixed and half-British force under the Duke of York: a success which had not been maintained on the two wings. A bulge of this sort in an attacking line is on the face of it disastrous. The enemy have only to be rapid in falling upon either flank of it and the bulge can be burst in. The French were rapid, and burst in the bulge was. By concentrating their forces against this one central part of the Allies they fought three to one.
