In August the THIRD DRAGOON GUARDS were engaged in a general attack upon the enemy's posts, near the Dymel; and afterwards crossed that river and advanced to the vicinity of Cassel. In the early part of November they were engaged in dislodging a French corps from its post near _Capelnhagen_. On the 6th and 7th of that month they skirmished with the enemy's advanced posts at _Eimbeck_, in the Electorate of Hanover. On the same evening the Dragoon Guards, with several other corps, marched through a heavy snow, and the following morning arrived at _Foorwohle_, where they erected their tents; but just as the encampment was formed, an alarm was given by the out-posts of the advance of the enemy in force. The British horsemen instantly formed, attacked the enemy with their accustomed gallantry, and drove them back with loss. Prince Ferdinand was a spectator of this act of gallantry, and expressed great admiration of the spirited conduct of the officers and men.[50] This warfare by detached parties, which occasioned considerable loss in men and horses from fatigue and exposure to inclement weather, produced no decisive results; and in the beginning of November the THIRD DRAGOON GUARDS went into quarters in East Friesland.
In the spring of 1762 the allies made an excursion into the country of Berg, where they raised contributions. On the 18th of June the main army encamped at Brakel, where the First and THIRD DRAGOON GUARDS formed a brigade under the command of Major-General the Earl of Pembroke. On the 20th of the same month the army advanced towards the Dymel; and the French, under Marshals d'Etrées and Soubise moved forward and encamped at _Groebenstien_; when a favourable opportunity presenting itself, Prince Ferdinand immediately made dispositions for attacking the enemy.
Moving from their camp at an early hour on the morning of the 24th of June the THIRD DRAGOON GUARDS, forming part of the centre column, crossed the Dymel between Libenau and Silen, and took part in surprising the enemy in their camp, and in driving them from their ground, with the loss of their camp equipage and many prisoners. At the same time a French corps, consisting of the grenadiers of France, the Royal Grenadiers, the Regiment of Aquitaine, and other troops, under the command of General Stainville, threw themselves into the woods near Wilhelmsthal, to cover the retreat of the army; when the THIRD DRAGOON GUARDS, with the main body of the allied army, surrounded the wood, and nearly every man of this French corps was either killed or taken prisoner, two battalions only escaping.
