The regiment quitted Canterbury in December, on route for Scotland; and in February, 1806, was established in quarters at Piershill barracks, Edinburgh, with Hamilton and Glasgow; but it was recalled to England in a few weeks afterwards, and occupied Manchester, Liverpool, and Chester.

On the 8th of August two troops were inspected at Liverpool by His Royal Highness the Duke of Gloucester, accompanied by the Duke of Clarence (afterwards King William IV.); their Royal Highnesses also saw the whole regiment at Manchester on the 25th of September, and expressed their approbation of its appearance and discipline in the most flattering terms.[21]

The regiment was reviewed on the 9th of June, 1807, at Manchester, by Major-General Fisher; and in the following month two troops marched to Nottingham: in the autumn the regiment occupied quarters at Birmingham (head-quarters), Nottingham, Coventry, Manchester, Liverpool, Chester, and Warrington.

In the summer of the following year great excitement prevailed in the manufacturing towns in Lancashire and the adjoining counties; and in May a serious riot took place at _Manchester_, in consequence of a bill, fixing the minimum of wages, having been rejected by parliament: so great was the violence of the rioters, that the FOURTH DRAGOON GUARDS and militia were obliged to use violent means, and unfortunately eight men were killed and several wounded. This severity did not, however, prevent another body of weavers assembling on the 1st of June, and committing many acts of violence and outrage; and the cavalry was again obliged to act. The weavers of other towns were equally outrageous; and at Rochdale they attacked and burnt the prison, and were only prevented committing further mischief by the arrival of a troop of the ROYAL IRISH DRAGOON GUARDS from Manchester.

The disturbed state of the manufacturing towns, and the numerous calls of the civil authorities for the aid of a military force, occasioned much harassing duty to the regiment throughout the summer, and these services were rendered particularly painful to the troops, from the necessity of frequently using coercive measures to restrain the lawless violence of the people.
