In 1777, the King's Own were reviewed at Newbury, and thence took up winter quarters at Blandford, Dorchester and Sherbourne. Early in 1778 they were ordered to Salisbury, there to be reviewed, and thence proceeded to Suffolk, and were encamped on Culford Heath, under the command of Lieutenant-General Warde, finally going into winter quarters in Sussex, and being employed there on coast duty during the remainder of the year. The regiment had, for many years, been in possession of a pair of Kettle Drums, in consequence of having taken them from the enemy, and on the 25th of December, 1778, an additional man and horse was placed upon the establishment, which gave the regiment its complement of Trumpeters besides the kettle drummer; being granted by His Majesty in compliance with a memorial from the Colonel[29].
1779
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.
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.
