A change of quarters took place in June and July, 1819, and the regiment was stationed at York, Sheffield, Leeds, and Huddersfield. In the middle of August five troops were employed in suppressing riots at Leeds; and in September one troop proceeded to Durham, in consequence of some commotions among the people of that city. A further alteration was made in the uniform this year: the coats were made with long skirts, with four bars of white lace with a blue worm upon the sleeves, two bars on each side of the collar; and four bars, two rows in each bar, across the breast. The colour of the cloth overalls was changed to blue-grey, with a blue stripe down the outside of the leg. The officers wore aiguillettes on the right shoulder, and a stripe of silver lace on their overalls. [Sidenote: 1820] The decease of His Majesty King George III. having taken place on the 29th of January, 1820, on the 31st of that month the troops of the FOURTH DRAGOON GUARDS at head-quarters attended the Lord Mayor, corporation, and societies of the city of York in solemn procession, while making proclamation of the accession of King George IV.; and on the 8th of February, 1820, they marched in procession at 8 o'clock, P.M., in funeral order to York minster, where a solemn dirge and funeral service was performed on the death of King George III. On the 11th of April three troops marched from York to assist the civil power in suppressing some serious disturbances which had occurred in the neighbourhood of Wakefield. A collision afterwards took place with the rioters near Sheffield, when one sergeant, one private, and two horses were wounded with pikes, many of which were found in possession of the people. [Sidenote: 1821] Another change of quarters took place in August of this year, and the regiment was stationed at Newcastle upon Tyne, Carlisle, Penrith, and Whitehaven; and in October it was inspected by Major-General Sir Andrew Barnard, at Newcastle. In March, 1821, it marched to Scotland, and was stationed at Piershill barracks, Edinburgh, Greenock, Irvine, and Ayr. On the 6th of June it was inspected by Major-General Sir Thomas Bradford; and, in August, the establishment was reduced to six troops. Previous to this date the troops were classed according to the colour of the horses, and the regiment consisted of two black troops, two brown, two bay, one bright bay, and one chestnut; when this reduction was ordered, the horses of one of the black troops, and of the chestnut troop, were transferred to the others; the horses thus became mixed, and they have since been trooped without reference to colour. The reduced establishment was 27 officers, 24 serjeants, 18 corporals, 6 trumpeters, 6 farriers, 281 privates and 253 troop horses. In September the regiment was again inspected by Major-General Sir Thomas Bradford; and in a few days afterwards the head-quarters were removed to Glasgow, where five troops were stationed, and one troop was quartered at Hamilton.
