Nine of these troops were formed into a brigade in 1758, under the command of one of the King's aides-de-camp, Colonel George Augustus Eliott, of the Horse Grenadier Guards; and they were employed in the expeditions to the coast of France under Charles Duke of Marlborough and Lieut.-General Bligh. They landed in France twice; skirmished with the French Cavalry; and throughout these enterprises they evinced activity, spirit, and general usefulness. After their return to England, they were augmented to 125 men per troop. At this period, the war on the Continent had involved most of the European states; and the extended and active operations which were taking place in Germany rendered it necessary for a British force to join the Allied Army under Prince Ferdinand of Brunswick. This gave rise to a further augmentation of the Army; and the increased estimation in which Light Cavalry was held induced the King to give directions for the raising of _entire Regiments of Light Dragoons_, in addition to the five Regiments of Horse, three of Dragoon Guards, and fourteen of Dragoons, already on the British and Irish establishments. The following corps were accordingly embodied:-- LIGHT DRAGOONS. _Incorporated in 1759._ FIFTEENTH, in England, by Colonel George A. Eliott;--now the Fifteenth, or the King's Hussars. SIXTEENTH, in England, by Lieut.-Colonel John Burgoyne;--now the Sixteenth, or the Queen's Lancers. SEVENTEENTH, in Scotland, by Captain Lord Aberdour;--disbanded in 1763. EIGHTEENTH, in England, by Lieut.-Colonel John Hale;--now the Seventeenth Lancers. NINETEENTH, in Ireland, by Lieut.-Colonel Lord Drogheda;--numbered the Eighteenth in 1763; constituted Hussars in 1807; and after performing much valuable service at home and abroad, it was disbanded at Newbridge, in Ireland, in 1821. _Incorporated in 1760._ TWENTIETH, in Ireland, by Captain Sir James Caldwell;--disbanded in 1763. TWENTY-FIRST, or Royal Foresters, in England by Lieut.-General the Marquis of Granby, and Colonel Lord Robert Sutton;--disbanded in 1763. After the peace of Fontainebleau, three of these corps were disbanded, and the other four continued in the service. The light troops attached to the heavy regiments were also disbanded, but a few men of each troop were afterwards equipped as Light Dragoons. A more perfect knowledge of the efficiency and capabilities of Light Cavalry, acquired during the campaigns in Germany and Portugal, had advanced the estimation in which that arm was held; and, in 1768, the TWELFTH Dragoons (one of the heavy regiments raised by King George I. in 1715), underwent a change of equipment and clothing, and was constituted a corps of _Light Dragoons_, by General Carpenter, in Ireland.
