The Hereditary Prince of Brunswick marched with a body of troops to the duchy of Cleves, and invested Wesel. The INNISKILLING dragoons and several other corps left the camp at Warbourg, on the 1st of October, under Major-General Waldegrave, to join the prince, and take part in the operations on the lower Rhine. The French, commanded by the Marquis de Castries, advanced to raise the siege of Wesel, and encamped half a league behind the convent of _Campen_, with Frischer's corps posted within the convent. The INNISKILLING dragoons passed the Rhine by a bridge two miles below Wesel, and having joined the Hereditary Prince, advanced at ten o'clock, on the evening of the 15th of October, to surprise the enemy's camp. It being necessary to dislodge the troops in the convent, the firing alarmed the French army, which instantly formed for battle. The allies having passed the convent, commenced the action at five o'clock on the morning of the 16th; and a succession of charges was continued with varied success until nine at night, when the Prince ordered a retreat. The SIXTH lost on this occasion two men and four horses killed; Lieutenant-Colonel Harvey, Major Hepburn, Cornet Sayer, five men and one horse wounded; and one man and horse taken by the enemy. After repassing the Rhine, the regiment was encamped at Bounnen, subsequently at Klein Reckum, and in December went into cantonments. [Sidenote: 1761] In February, 1761, the regiment took part in a successful incursion into the quarters occupied by the French army; when the allies, advancing through a heavy snow, drove their opponents before them many leagues, captured several strong towns with extensive magazines of forage and provisions, but were subsequently obliged to retire. During the campaign of 1761 the regiment was brigaded with the royals and tenth dragoons, commanded by Major-General Eliott. It was employed in several manœuvres, and was in position in the middle of July, on the rivers Asse and Lippe in Westphalia, forming part of the division under the Prince of Anhalt. On the 15th of July, the enemy attacked the Marquis of Granby's division at _Kirch-Denkern_, when the INNISKILLING dragoons crossed the Asse river to support the infantry, and the French were driven back. The action was renewed on the following day, and the enemy was again repulsed with serious loss; but owing to the scene of conflict being in a thickly-wooded country, interspersed with marshy ground, the services of the regiment were limited to supporting the infantry. The SIXTH dragoons were subsequently employed in operations on the Dymel; in November they were engaged in the electorate of Hanover, where several sharp skirmishes occurred, in which they took part, in severe weather, and were sometimes encamped in the snow. They eventually went into cantonments in Friesland. [Sidenote: 1762]
