The rank of major-general was conferred on Colonel Campbell in 1759; in 1761 his uncle, Archibald, third Duke of Argyle, died, when his father, General John Campbell of the Scots Greys, succeeded to that title, and Major-General Campbell of the FOURTEENTH Dragoons obtained the designation of MARQUIS OF LORNE: he was removed to the first, the royal regiment of foot, in 1765, and was succeeded in the command of the FOURTEENTH dragoons, by Colonel Charles Fitzroy, (afterwards Lord Southampton) whose regiment of foot had been disbanded at the peace of Fontainbleau in 1763. [Sidenote: 1768] On the 19th December, 1768, a warrant was issued, by authority of King George III., for regulating the standards, guidons, clothing, &c., of the regiments of cavalry, in which it was directed, that the uniform of the FOURTEENTH dragoons should be red, with _lemon-coloured_ facings, without lappels, with silver lace; the uniform, &c., being the same as prescribed by the Royal Warrant of the 1st July, 1751. [Sidenote: 1772] Colonel Fitzroy was promoted to the rank of major-general and removed to the third dragoons, in 1772, when King George III. conferred the colonelcy of the FOURTEENTH dragoons on Lieut.-General Daniel Webb, from the eighth foot. [Sidenote: 1773] Lieut.-General Webb died in 1773, and was succeeded by Colonel George Warde, from the lieut.-colonelcy of the fourth dragoons. [Sidenote: 1775] [Sidenote: 1776] [Sidenote: 1777] Hostilities between Great Britain and her North American Colonies commenced in 1775, and the rugged valleys and trackless forests which became the theatre of this war, were not adapted for the operations of heavy dragoons. The necessity of having a greater proportion of light cavalry had become apparent, and in 1776, the FOURTEENTH, which were then in Ireland, were constituted a corps of LIGHT DRAGOONS. The standard height for men and horses was reduced; the cocked hats were replaced by helmets; arms and appointments of a lighter description were adopted, and in the annual army list for 1777, the regiment was designated, "THE FOURTEENTH LIGHT DRAGOONS." [Sidenote: 1778] In 1778, Major-General Warde was removed to the first Irish horse, now fourth dragoon guards, and was succeeded in the colonelcy of the FOURTEENTH light dragoons, by Major-General Robert Sloper. [Sidenote: 1784] In 1784 the clothing of the light dragoon regiments was changed from scarlet to _dark blue_; and the following orders were issued on this subject, dated-- _Adjutant General's Office, Dublin, 18th May, 1784._ 'His Majesty's pleasure having been signified to the Lord Lieutenant, that the clothing of the light dragoon regiments shall hereafter be made in conformity to the following regulations, it is the Commander-in-Chief's order that the said regulations be observed accordingly.' _Regulations for the Clothing of the Light Dragoons._
