Being opposed by a French army of very superior numbers, the allies were restricted to defensive operations, and the SEVENTH took part in several toilsome marches and skirmishes. At length thirty thousand French troops crossed the river Dymel to cut off the communication of the allies with Westphalia, and a favourable opportunity occurring to attack this detached force, the QUEEN'S OWN dragoons, with several other corps, under the Hereditary Prince of Brunswick, advanced to Liebenau, where they passed the Dymel, and making a detour of many miles, gained the left flank of the enemy's position at _Warbourg_, on the 31st of July. Prince Ferdinand was advancing with the main body against the enemy's front; but before his arrival, the enemy had been attacked in flank and rear, and were retiring. The cavalry under the Marquis of Granby and Lieut.-General Mostyn arrived at a favourable moment; a gallant charge of the British squadrons decided the fortune of the day, and the French made a precipitate retreat across the Dymel. The SEVENTH dragoons supported the infantry in the attack of the enemy's flank, and by a spirited charge towards the close of the action, contributed to the success of the day. The conduct of the British cavalry was commended by the Marquis of Granby, in his public despatch, and Prince Ferdinand declared in general orders, that "_all the British cavalry performed prodigies of valour_." The regiment being eager in the pursuit, had four men and horses captured by the enemy; three of the men, however, escaped and rejoined the regiment. Lieut.-General Sir John Cope, K.B., died on the 28th of July, 1760; and King George II. conferred the colonelcy on Lieut.-General Mostyn, from the fifth, royal Irish, regiment of dragoons. The SEVENTH dragoons were encamped near the banks of the Dymel, until winter, when the soldiers were directed to build huts to protect themselves and horses from severe weather. They subsequently went into cantonments in the villages in that part of the bishopric of Paderborn. [Sidenote: 1761] The army was suddenly called from its winter quarters in February, 1761, and penetrating, during a heavy snow, into the enemy's cantonments, captured several towns and extensive magazines of forage and provision; but afterwards returned to its former quarters, and the SEVENTH were again quartered in villages in the bishopric of Paderborn.
