After leaving their winter quarters about the middle of April, 1745, the KING'S OWN were encamped a short time near Brussels, where they were reviewed by his Royal Highness the Duke of Cumberland. They were afterwards assembled with the army at Soignies. The French having assembled a numerous army and besieged Tournay, the Duke of Cumberland resolved to attempt the relief of that fortress; the army, accordingly, advanced, and on the 28th of April took post at Leuse. On the following day a squadron of the KING'S OWN was employed, with other troops, in driving back the enemy's advanced-posts, and on the 30th the battle of _Fontenoy_ took place; when the gallant efforts and brilliant success of the British were rendered unavailing by the failure of the Dutch. After an action of several hours the KING'S OWN dragoons were ordered forward, and they charged the enemy with their accustomed gallantry; but under such disadvantageous circumstances that their manly efforts only retarded the fate of the day. The Duke of Cumberland ordered a retreat, and the army marched to the vicinity of Aeth. The enemy had great advantage in numbers, in artillery, and in the favourable ground they occupied; the loss was nearly equal on both sides, and the Allies lost no honour, though compelled to retire. The KING'S OWN had nine private men, and twenty-eight horses, killed; Captain Wade, Quarter-Master Corbidge, fourteen private men, and thirty-four horses wounded;--and Cornet Bland, two non-commissioned-officers, fifteen men, and twenty-three horses missing. The regiment was afterwards encamped on the banks of the Dender, near Lessines; from whence it proceeded with the army on the 30th of June, to Grammont in West Flanders, and was subsequently encamped before Brussels. In the mean time Charles-Edward, eldest son of the Pretender, had arrived in Scotland, and, being joined by several of the highland clans, he asserted his father's pretensions to the throne. There being few troops in Scotland at this time, the rebellion soon made alarming progress; when orders were given for the return of several regiments from the continent, and the KING'S OWN were among the first troops ordered home.
