With the retreat of the two sorely tried columns and the suspension of Clerfayt's attack between Lincelles and Roncq, the battle of Tourcoing ended. It was a victory of which the young French generals had reason to be proud. The main attack was vigorously conducted, and the two-to-one numerical superiority which the French possessed at the decisive point is the best testimony at once to Souham's generalship and to Vandamme's bravery. As for the Allies, those of them who took part in the battle at all, generals and soldiers, covered themselves with glory, but the inaction of two-thirds of Coburg's army was the bankruptcy declaration of the old strategical system. The Allies lost, on this day, about 4000 killed and wounded and 1500 prisoners besides 60 guns. The French loss, which was probably heavier, is not known. The duke of York defeated, Souham at once turned his attention to Clerfayt, against whom he directed all the forces he could gather after a day's "horde-tactics." The Austrian commander, however, withdrew over the river unharmed. On the 19th he was at Rousselaer and Ingelminster, 9 or 10 m. north of Courtrai, while Coburg's forces assembled and encamped in a strong position some 3 m. west and north-west of Tournai, the Hanoverians remaining out in advance of the right on the Espierre. Souham's victory, thanks to his geographical position, had merely given him air. The Allies, except for the loss of some 5500 men, were in no way worse off. The plan had failed, but the army as a whole had not been defeated, while the troops of the duke of York and Otto were far too well disciplined not to take their defeat as "all in the day's work." Souham was still on the Lys and midway between the two allied masses, able to strike each in turn or liable to be crushed between them in proportion as the opposing generals calculated time, space and endurance accurately. Souham, therefore, as early as the 19th, had decided that until Clerfayt had been pushed back to his old positions near Thielt he could not deal with the main body of the Allies on the side of Tournai, and he had left Bonnaud to hold the latter while he concentrated most of his forces towards Courtrai. This move had the desired effect, for Clerfayt retired without a contest, and on the 21st of May Souham issued his orders for an advance on Coburg's army, which, as he knew, had meantime been reinforced. Vandamme alone was left to face Clerfayt, and this time with outposts far out, at Ingelminster and Roosebeke, so as to ensure his chief, not a few hours', but two or three days' freedom from interference. Battle of Tournai.
