In February, 1800, the KING'S OWN marched to Trowbridge, but only remained there a few weeks, and then proceeded to Chester to be reviewed. At this place an augmentation of two troops took place, making a total of ten; and on the 22nd of September, the whole regiment marched to Lancashire, thence to Carlisle, and, in December, to Scotland, the head-quarters being established at Hamilton; three troops, under the command of Major Wade, being detached to Carlisle and Penrith. At Hamilton, the regiment was reviewed by Major-Generals Erskine and Vyse, and the present system of casting horses annually first introduced; and as it was considered the peculiar privilege of the regiment to have _black horses_ exclusively, those that had the slightest shade of brown, were sent to the fourth dragoon guards, none but black horses being retained, with the exception of one white for the kettle-drums. [Sidenote: 1802] [Sidenote: 1803] [Sidenote: 1804] After the peace of Amiens in 1802, two troops were reduced; the number of men in the others being also reduced from 100 to 64; and, on the 11th of August, the KING'S OWN embarked at Port-Patrick for Ireland, proceeded to Dundalk, and in the spring of 1803 marched to Belturbet. Here they were reviewed by Major-General Sir James Afleck, and were actively employed in patrolling the country during the excitement caused by the disturbances in Dublin, to which place they proceeded in March, 1804, and were quartered in the royal barracks.[31] [Sidenote: 1805] [Sidenote: 1806] On the 5th of April, 1805, the first division, immediately followed by the others, embarked for Liverpool, and marched to Nottingham, where the regiment remained for two years; the second year's halt being at the express request of the magistrates of Nottingham and Louth. The war having been resumed, two additional troops were added to the establishment. [Sidenote: 1807] The regiment marched to Chichester in May 1807, and being there reviewed by Major-General Hugonin, proceeded to Brighton, and was encamped on the hills above the present barracks, for the purpose of being reviewed, in conjunction with the first dragoon guards, by His Royal Highness the Duke of York. On the breaking up of the camp, the THIRD marched to Chichester, but were shortly ordered to Canterbury, where a brigade was formed, consisting of the second dragoon guards, and third and fourth dragoons. [Sidenote: 1809] In January, 1809, the regiment received orders to embark at Portsmouth, for the purpose of joining the army in Spain, under Lieut.-General Sir John Moore, and had advanced some days' march, when it was recalled, on the arrival of the news of the retreat of the British troops to Corunna.
