After the review the INNISKILLING dragoons marched into cantonments in Worcestershire; in 1768 the head-quarters were removed to Lewes; in 1769 to Ipswich; and in 1770 to York. [Sidenote: 1771] [Sidenote: 1772] [Sidenote: 1773] [Sidenote: 1774] In the spring of the following year the regiment proceeded to Scotland; but returned to England in the beginning of 1772, and was stationed in Lancashire, the head-quarters being established at Manchester; from whence they were removed in 1773 to Worcester, and in 1774 to Canterbury. [Sidenote: 1775] A change of quarters took place in the summer of 1775, and the regiment was stationed in Northamptonshire and Lincolnshire, with the head-quarters at Northampton. On the decease of General Cholmondeley, in October, 1775, King George III. conferred the colonelcy on Lieutenant-General Edward Harvey, who so highly distinguished himself at the head of the regiment in Germany during the seven years' war. [Sidenote: 1776] [Sidenote: 1777] In the early part of 1776 the SIXTH dragoons commenced their march for Scotland; from whence they returned in the beginning of 1777, and were cantoned in Warwickshire and Staffordshire, the head-quarters being at Coventry. [Sidenote: 1778] The colonelcy having become vacant by the decease of General Harvey, it was conferred on Lieutenant-General James Johnston, from the first Irish horse, now fourth dragoon guards, by commission dated the 2nd of April, 1778. Meanwhile the American war had commenced, and the French monarch having agreed to aid the revolted colonies, war was declared against France. The British army was augmented, and one hundred men and horses were added to the INNISKILLING dragoons; but the scene of conflict was so little adapted for cavalry, that the heavy dragoon regiments were not called upon to quit the United Kingdom. The head-quarters were removed to Salisbury in May, 1778; and a further augmentation of forty-eight men, who were to be mounted on small horses and equipped as light dragoons, was added to the regiment. [Sidenote: 1779] In April, 1779, the men equipped as light cavalry were incorporated, with the men of the third dragoon guards, and first and eleventh dragoons, into a regiment, which was numbered the twentieth light dragoons. During the following summer, the SIXTH, and five other regiments of cavalry, were encamped on Salisbury Plain, under Lieutenant-General Johnston. [Sidenote: 1780] [Sidenote: 1781] [Sidenote: 1782] [Sidenote: 1783] In the two following years the regiment occupied quarters in Gloucestershire and Worcestershire; in 1782 it was stationed in Dorsetshire, with the head-quarters at Dorchester; and in 1783 it was removed into Northamptonshire and Leicestershire. The American war had, in the mean time, terminated, and the establishment was reduced to two hundred and thirty-two officers and men. [Sidenote: 1784] [Sidenote: 1785]
