Thus, fortress after fortress fell before the superior skill of the commanders and the prowess of the troops composing the allied army. After the surrender of Aire, the TENTH marched to Courtray, a town of Hainault, situate on the river Lys, and defended by towers and a strong castle erected by Philip, Duke of Burgundy, in 1385: at this place the regiment passed the winter, and its losses were replaced by recruits from England. [Sidenote: 1711] Towards the end of April, 1711, the regiment was again in the field; it was reviewed at the camp at Warde by the Duke of Marlborough, on the 8th of June, and commended for its appearance and discipline: it afterwards encamped on the plains of Lens. A new line of formidable entrenchments, defended by a powerful French army under the command of Marshal Villars, appeared as a barrier to arrest the victorious career of the allied army; but the British General, by menacing the enemy's left, and making ostentatious preparations for storming the works at that point, occasioned the French troops to be drawn to that quarter; in the meantime he had privately assembled a number of corps at Douay, and by a forced march these formidable works were passed at the unguarded post of _Arleux_. The TENTH regiment of foot had the honor to take part in forcing these lines, on which occasion the British General developed that sublimity of military talent which has justly stamped this campaign as peculiarly scientific and glorious. The regiment was afterwards engaged in the siege of _Bouchain_, a well-fortified town, situate on both sides of the river Scheldt: and in carrying on the attacks, and performing its turn of duty in the trenches, the regiment had several men killed and wounded. The garrison surrendered in September, and after the damaged works were repaired, the TENTH went into winter-quarters. [Sidenote: 1712] The French monarch saw his generals overmatched, his soldiers beaten and dispirited, the barriers of his kingdom trampled down, and the great Duke of Marlborough ready to lead his victorious legions into the heart of France. Under these circumstances the ambitious Louis XIV. solicited peace. Negociations commenced before the TENTH foot took the field in April, 1712: the British troops were, however, assembled near Tournay, and the Duke of Ormond assumed the command in succession to the Duke of Marlborough. According to the returns of this period, the regiment brought six hundred and twenty-three rank and file into the field.
