In the spring of 1779, the men of the regiment equipped as light dragoons, were incorporated, with detachments from other corps, into a regiment, which was numbered the twenty-first light dragoons. [Sidenote: 1780] In consequence of the alarming riots in London in 1780, the regiment was ordered thither, and was quartered about Islington, furnishing the piquets in Portman Square during the trial of Lord George Gordon, and having a party stationed in Apsley House, then the property of Lord Chancellor Bathurst. [Sidenote: 1781] [Sidenote: 1782] [Sidenote: 1783] In 1781, having been reviewed by His Majesty in Hyde Park, the KING'S OWN marched into Suffolk; and in 1782, were quartered at Derby, Leicester, and Nottingham, thence proceeding to Manchester in the autumn. In 1783, after the spring review they marched to Newcastle-on-Tyne and Durham, assembled at the latter place for inspection in September, and then returned to their old quarters for the winter. [Sidenote: 1784] [Sidenote: 1785] [Sidenote: 1786] The KING'S OWN, for the third time in fourteen years, entered Scotland in 1784, and took up their old quarters at Dalkeith, Leith, and Haddington. Here they were inspected by Major-General Mackay, and soon after detached a troop to Dumfries. In July, 1785, the six troops were at Manchester, and thence, in 1786, proceeded to Worcester, then a general place of inspection for cavalry. At this station they were inspected by Major-General Philipson, and, after a stay of about six weeks, went into winter quarters at Hereford, Ludlow, and Leominster. [Sidenote: 1787] [Sidenote: 1788] In May, 1787, the regiment assembled at Hereford to be reviewed by Major-General Douglas. It was ordered, on the rumour of a Russian armament, to hold itself in readiness to join any force that might be assembled; but, nothing taking place, it went into winter quarters at Dorchester, Blandford, and Poole. In 1788, it moved to Salisbury, was there reviewed, and then quartered at Winchester. [Sidenote: 1789] [Sidenote: 1790] Early in 1789, the regiment marched to Reading. It was there reviewed by His Majesty, George III., on Ashford Common, and marched to Ipswich, where it remained until 1790, and, being then reviewed at Stamford, took up winter quarters at York and Lincoln. [Sidenote: 1791] [Sidenote: 1792] At York all the troops assembled for inspection in the spring of 1791, and, for the fourth time marched to Scotland and were for two years quartered at Dumfries, being in that period twice inspected by Major-General Leslie.
