Lieutenant-General Neville died on the 5th of August, 1744, and was succeeded in the Colonelcy of the regiment by Richard Viscount Cobham, who, when Sir Richard Temple, highly distinguished himself in the wars of Queen Anne. He was removed in 1745 to the Tenth Dragoons, when His Majesty conferred the command of this regiment on Major-General Thomas Wentworth, from the Twenty-fourth Foot. [Sidenote: 1746] When this regiment was first raised, it ranked as SEVENTH HORSE; in 1690, the Fifth regiment of Horse was disbanded in Ireland, and the Sixth Horse became Fifth, and this regiment obtained rank as SIXTH HORSE, which rank it held until December, 1746, when the First Horse,--the royal regiment of Horse Guards,--ceased to bear a number: the Second, Third, and Fourth Horse were then constituted the First, Second, and Third Dragoon Guards; and this regiment was styled the SECOND IRISH HORSE, and sometimes called the GREEN HORSE from the colour of its facings. [Sidenote: 1747] In 1747, Major-General Thomas Wentworth died at Turin, where he was employed in a diplomatic capacity, and was succeeded in the Colonelcy of the SECOND IRISH HORSE, by Major-General Thomas Bligh, from the Twelfth Dragoons. [Sidenote: 1748] [Sidenote: 1749] On the conclusion of a treaty of peace at Aix-la-Chapelle, a considerable diminution was made in the strength of the regular army, and in 1749 the establishment of the SECOND IRISH HORSE was reduced to twenty-one private men per troop. [Sidenote: 1751] From the period of the formation of the regiment, several alterations had, from time to time, been made in the uniform and standards. The practice of having a standard to each troop had been discontinued, and one to each squadron was substituted. In 1742, King George II. caused a series of coloured engravings, representing the uniform of the several regiments of the army to be executed; and, as a few alterations had subsequently been made, a warrant was issued on the 1st of July, 1751, regulating the standards, colours, and clothing of the several regiments, from which the following particulars have been extracted relative to the SECOND IRISH HORSE:-- COATS.--Scarlet, the facings and lapels of full green; the button-holes worked with yellow, the buttons set on two and two; and a long slash pocket in each skirt. WAISTCOATS} } full green. BREECHES } HATS.--Three-cornered cocked-hats, bound with yellow lace, and ornamented with a brass loop and a black cockade. BOOTS.--Made of jacked leather. TRUMPETERS.--Clothed in full green coats, faced and lapelled with red, and ornamented with white lace, having a red stripe down the middle: their waistcoats and breeches of red cloth.
