In April the four troops on foreign service were assembled with the army near Cateau, and were engaged in the general attack made on the enemy's positions at _Prémont_, &c. on the 17th of April, when Captain-Lieutenant the Honourable Thomas Carlton, of the regiment, was killed. The siege of Landrécies was immediately undertaken: the ROYAL DRAGOONS formed part of the covering army, and on the 24th of April were engaged in an affair with the enemy at _Villers en Couché_, when the French lost twelve hundred men and three pieces of cannon: the ROYALS had one man and two horses killed, and two men and three horses wounded. The ROYAL DRAGOONS had another opportunity of distinguishing themselves on the 26th of April at _Cateau_. The enemy had marched out of Cambray, and at daybreak attacked the British army. The Duke of York detached the ROYALS and seven other cavalry regiments to turn the left flank of the French army: this movement was attended with the most brilliant success; the enemy was overthrown with immense slaughter; the rout became general--cavalry and infantry, mingled in promiscuous crowds, were scattered over the plains, and the fugitives fell beneath the sabres of the British dragoons, who captured the French commander, Lieut.-General Chapuy, and thirty-five pieces of cannon. The Duke of York, in his account of this action, observes, "THE BEHAVIOUR OF THE BRITISH CAVALRY HAS BEEN BEYOND ALL PRAISE." The ROYAL DRAGOONS were among the corps which were declared in general orders to have "ACQUIRED IMMORTAL HONOUR." Their loss on this occasion was six men and twelve horses killed; with Lieutenant Froom, two serjeants, eleven men, and fourteen horses wounded. After the capture of _Landrécies_ the ROYAL DRAGOONS marched to the vicinity of _Tournay_, where they were again engaged with the enemy on the 10th of May; and the Duke of York observed in his public despatch, that the troops had "well supported the reputation acquired on the 26th of last month." The loss of the ROYALS was only two horses killed, and one man and three horses wounded. The ROYALS were in reserve when the attack was made on the French positions on the 17th of May. The army afterwards resumed its post before _Tournay_, where it was attacked on the 22d of May by General Pichegru with an immense force. The British heavy cavalry had, it appears, become a terror to the enemy, for Brown, in his Journal, observes (22d May), "A column of five or six thousand men made its appearance towards our left, on which account the brigade of guards and the British heavy cavalry remained ready for action on their camp ground; but the French, observing our advantageous situation, _and dreading the thought of meeting the British cavalry a second time on an open plain_, thought proper not to approach." Finally the French were repulsed at every point of attack, and retreated in the evening.
