On the 5th of April, 1759, the colonelcy, having become vacant by the decease of General Hawley, was conferred on HENRY SEYMOUR CONWAY, from the fourth Irish horse, now seventh dragoon guards. In the same year the establishment of each of the six heavy troops was augmented to sixty private men, and the light troop to eighty-nine; making a total of five hundred and forty-four officers and men; and in the following year the light troop was further augmented to four officers, one quarter-master, four serjeants, four corporals, two drummers, and one hundred and eighteen private men. In the mean time a British army had proceeded to Germany, and was serving in conjunction with the Hanoverian, Hessian, and Brunswick troops, commanded by Prince Ferdinand, Duke of Brunswick; and in the spring of 1760 the ROYAL DRAGOONS, commanded by Lieutenant-Colonel JAMES JOHNSTON,[49] embarked for foreign service, and, having landed at Bremen, in Lower Saxony, on the 16th and 17th of April, joined the army encamped near Fritzlar, in the principality of Lower Hesse, on the 21st of that month. On the 22nd they were reviewed by the Duke of Brunswick, who was pleased to express his approbation of their appearance. After much manœuvring and skirmishing, thirty thousand French troops, commanded by the Chevalier de Muy, crossed the Dymel to cut off the communication of the allied army with Westphalia. The ROYAL DRAGOONS, with several other corps, were immediately sent forward to Liebenau, under the command of the Hereditary Prince of Brunswick, to secure the bridge across the Dymel; and being followed by the main body, the Prince advanced to the vicinity of _Warbourg_, and reconnoitred the French forces in position near that place, whom he resolved to attack on the following day.
