The TWELFTH regiment, commanded by Major Frederick Bowes, consisting of eight hundred and fifteen rank and file, took part in numerous operations, and was engaged in the general attack on the French positions on the 17th and 18th of May. On the latter day, the TWELFTH were engaged in driving the enemy from _Werwick_, and in forcing the passage of the river _Lys_, on which occasion they highly distinguished themselves; but the operations on the above two days were not successful, from the want of a more perfect combination in the movements of the several divisions, and from the superior numbers of the enemy. In division orders, dated Camp near Tournay, 20th May, 1794, Major-General Whyte stated 'he had great pleasure in informing the British troops, that General Count Clerfait has highly approved of their spirited conduct in the field, and great exertions in going through such excessive fatigues, as they necessarily have had since their first movement from Ostend. Major-General Whyte laments the loss sustained by the eighth light dragoons, whose spirited and distinguished gallantry, led on by Lieut.-Colonel Hart, has gained them the highest honour; and he desires his thanks may be accepted by the commanding officers, and all the officers and men of the thirty-eighth and fifty-fifth regiments; and also by Major BOWES and the officers and men of the TWELFTH regiment, whose conduct has been highly approved of by Major-General Hammerstein, under whose immediate command they served. To Lieut.-Colonel Hart, who led on the squadron of the eighth light dragoons to the attack at Rousbeck, his best and distinguished thanks are due; and also to Lieut.-Colonel M'Donald, who led on the fifty-fifth regiment to support the attack on the front. He is perfectly convinced the same praise would have been due to Lieut.-Colonel Pitcairn of the thirty-eighth, had they been called into action.' The TWELFTH foot continued to serve under General Count Clerfait, and when the French besieged _Ypres_, with thirty thousand men, with a covering army of twenty-five thousand, the regiment was engaged in the attempt to relieve that fortress. The Austrian advance-guard was repulsed at Olglede on the 7th of June; but the French were defeated in their attempt on Rouselaer. Still entertaining hopes of being able to raise the siege, Count Clerfait attacked the French again on the 13th of June, at Hoogledge, and Major-General Hammerstein engaged a body of the enemy, of very superior numbers, at Kootmarke, and was repulsed. He afterwards retreated to Bruges, detaching the eighth light dragoons, and thirty-eighth and fifty-fifth foot to Ostend.
