1776
1783
At this low establishment the regiment continued until the breaking out of the unfortunate contest between Great Britain and her North American colonies, when an augmentation of ten private men per troop was made to its numbers. No further alteration appears to have been made until the conclusion of the war, when, the independence of the United States having been acknowledged, its establishment was reduced to its former numbers.
1788
At this establishment it continued until the spring of 1788; when King George III., having resolved to form the two troops of Life Guards and two troops of Horse Grenadier Guards into two regiments of Life Guards on a similar establishment to that of the old regiments of horse, and to reduce the four regiments of horse on the Irish establishment to the pay of dragoons, with the title of Dragoon Guards, His Majesty's pleasure was communicated to the regiments in Ireland, in a General Order dated the 14th of February, 1788; and the Second Irish Horse was thus constituted the Fifth Dragoon Guards. In consequence of the regiment being placed upon a decreased rate of pay, compensation was given to the officers; to the colonel 150l. per year; to the lieutenant-colonel a gratuity of 575l.; to the major 525l.; captains, each, 475l.; captain-lieutenant and lieutenants, each, 350l.; and the cornets, each, 250l. Every private man had the option of his discharge, or a bounty of two guineas if he continued to serve.
Several alterations were made in the uniform of the regiment. The officers were directed to wear an epaulette on each shoulder. The flask-string was removed from the pouch belt, and the width of the belts reduced from four inches and a half to three inches; and the equipment was assimilated, in every particular, to that of the regiments of dragoons.
The establishment was fixed at one colonel and captain, one lieutenant-colonel and captain, one major and captain, three captains, six lieutenants, six cornets, one chaplain, one adjutant, one surgeon, six troop quarter-masters, six serjeants, twelve corporals, six trumpeters, one hundred and fourteen private men, and six dismounted men. The several alterations having been completed, the change of establishment took place on the 1st of April, 1788, and from this date the regiment has borne the title of Fifth Dragoon Guards; but the appellation of Green Horse has never been entirely discontinued.
1789
1790
In the following year, the regiment lost its colonel, General the Honourable John Fitz-William, who was succeeded on the 27th of August, 1789, by Lieutenant-General John Douglas, from the Fourteenth Foot. Lieutenant-General Douglas died on the 10th of November, 1790, and was succeeded by Major-General Thomas Bland, from the Lieutenant-Colonelcy of the Seventh Dragoons.
1793
After passing a period of nearly eighty years in Ireland, the regiment, having previously had a considerable augmentation made to its numbers, was ordered to hold itself in readiness for foreign service. This event was occasioned by the revolution which had taken place in France, where a party of republicans had seized the reins of government, had imprisoned the royal family, and had brought their sovereign to the scaffold; a proceeding which disorganized the state of society in one of the most civilized parts of the world,—gave rise to the formation of a new dynasty,—removed the basis on which the sovereign power was established,—and involved the great European states in a succession of destructive wars for a period of more than twenty years. Great Britain joined the confederacy against the regicide government of France, and sent, in the spring of 1793, a body of troops to the Netherlands, under the command of His Royal Highness the Duke of York. At the close of the summer, reinforcements were sent to Flanders, and on the 18th and 19th of September, the Fifth Dragoon Guards embarked at Dublin for the same destination.
