The regiment remained as part of the army of occupation until May 1816, when, having transferred two sergeants and twenty five rank and file to the Staff Corps of Cavalry, and two hundred and fifty horses to other regiments, the Fifteenth left Calais for England.
Assembling at Canterbury, the regiment marched to Hounslow heath, to be reviewed on the 1st June by the Duke of York, who expressed his approval of its appearance and discipline.
Following the review the regiment marched to Nottingham, Birmingham, and Wolverhampton, where it was engaged in assisting the civil power, particularly in Birmingham in October, when several rioters were wounded, and a number imprisoned.
