The allies commenced operations early in the spring of 1759, and, having gained considerable advantage over the enemy in the country of Hesse, afterwards attacked (13th of April) the French army commanded by the Duke of Broglio in its position at _Bergen_. In this action the THIRD DRAGOON GUARDS supported the attack of the infantry, and were subsequently brought forward to menace the enemy's front; but it was found impracticable to force the position, and during the following night the allies retired, nor were they enabled to make a stand against the superior numbers of the enemy for some time afterwards. During this campaign the regiment was formed in brigade with the Scots Greys and Tenth Dragoons: and on the 17th of July it was encamped on Petershagen Heath, a few miles from _Minden_, and near the strong position occupied by the French army under the Duke de Broglio and Marshal Contades. On the 29th of July the allies advanced and took post at Hillé, and the THIRD DRAGOON GUARDS were encamped on the extreme right of the cavalry. Prince Ferdinand having, by several manœuvres, succeeded in drawing the French army from its strong post in front of _Minden_, a general engagement was fought on the 1st of August, when the valour of the British infantry decided the fortune of the day, and the enemy, after a sharp contest, sustained a decisive defeat, with the loss of forty-three pieces of cannon, ten pair of colours, and seven standards. At the commencement of the action the THIRD DRAGOON GUARDS were posted, with several other corps, under Lord George Sackville,[46] behind a thick wood on the right of the army, and, although these troops were not brought forward in time to share in the conflict and glories of the day, yet they afterwards highly distinguished themselves in the pursuit of the enemy a distance of about two hundred miles, in which great difficulties were overcome, and several French corps were nearly annihilated. The THIRD DRAGOON GUARDS took part in the several manœuvres and skirmishes of this campaign, which were continued throughout the year. In November the regiment was posted on the banks of the river Lahn, and it subsequently occupied cantonments near Osnaburg. [Sidenote: 1760]
