The accession of the house of Hanover to the throne of Great Britain and Ireland, was the commencement of a dynasty under which this kingdom has attained a splendid elevation of naval, military, commercial, and political importance; has extended its possessions in remote countries;--and its armies have fought and conquered in every quarter of the globe. The first year of His Majesty's reign had, however, not expired, when it was found necessary to augment the regular army, and the FOURTEENTH, (THE KING'S) REGIMENT OF LIGHT DRAGOONS, is one of the corps incorporated on that occasion. It was raised in South Britain, by Brigadier-General JAMES DORMER, who had acquired a reputation in the war of the Spanish succession; and the following officers were appointed to the regiment, by commissions dated the 22nd July, 1715. _Captains._ _Lieutenants._ _Cornets._ James Dormer (col). Jas. Stevens (cap.-lt.) Edward Stroude. H. Killegrew (lt.-col.) Henry Lasale. Thomas Ellis. Sol. Rapin. (major) Peter Davenport. Thomas Delahaye. Henry Pelham. Jonathan Pirke. William Hamilton. William Boyle. Cuthbert Smith. Rigley Molyneux. Beverly Newcommin. James Flemming. Andrew Forrester. His Majesty's protestant subjects arrayed themselves under the royal standard with great cheerfulness, but before the regiment was complete in men and horses, the arrangements of the Jacobites were in such a state of forwardness, that the Pretender's standard was raised in Scotland by the Earl of Mar, who was soon at the head of ten thousand men. A body of rebels having penetrated into Lancashire, DORMER'S dragoons were among the corps directed to advance, under Major-General Wills, and fight the insurgent bands: the regiment was formed in brigade with Pitt's horse, now second dragoon guards, under its Colonel, Brigadier-General Dormer. Arriving at _Preston_, about three o'clock in the afternoon of the 12th of November, the rebels were found in force in the town, with the avenues barricaded and defended by cannon. The FOURTEENTH dragoons were directed to dismount and form as infantry, to take part in storming the avenue leading to Lancaster, in which they were assisted by Wynne's (ninth), and a squadron of Stanhope's dragoons (afterwards disbanded) under Brigadier-Generals Dormer and Munden; Pitt's horse, Munden's (thirteenth), and a squadron of Stanhope's dragoons forming in support. The first barrier was carried with great gallantry; but the inner barricade could not be forced for want of cannon. The houses were afterwards set on fire, and measures adopted to prevent the escape of the rebels, who were eventually forced to surrender at discretion. The regiment had three men and sixteen horses killed on this occasion, Brigadier-General Dormer, and four private soldiers wounded.
