It was laid down as a rule, that no officer should be appointed to the Horse Brigade, who had not been on foreign service: but as this rule was occasionally broken, it was decided in July 1805 that any officers who had been appointed to the Horse Artillery, prior to having been on foreign service, should “(to avoid any officers being confined to one species of duty) be liable after three or four years’ service in the Horse Brigade to be exchanged again into the Battalions, so that they may take their share of duty on foreign service, and obtain that experience which is necessary to an Artillery officer, as he advances in the Regiment.” For the information of the general reader it should here be stated, that prior to 1861, when the amalgamation of the Imperial and East India Company’s armies took place, the Royal Horse Artillery never went abroad except on active service. Since 1861, however, India has opened a field of foreign service for this branch of the Regiment: and fifteen batteries of service Horse Artillery are to be found in that country, against sixteen at home.

An order dated 1st November, 1806, lays down the following rules for the dress of officers:--“Except at dress parades the blue Regimental overalls are to be worn till dinner-time in place of the blue pantaloons, which is to be the afternoon dress when at home. At all parades, whether mounted or dismounted, and during the day, the black velvet stock is to be worn, with an inch of shirt collar over it: no other white to be shown. In the evenings, it is requested that black silk handkerchiefs may be substituted with the same proportion of shirt collar over them. When officers are dressed for a ball, evening party, or dine out, they are to wear the jacket open, white pantaloons, plain white waistcoat (with sash over it), light sword, regulation sword-knot, black belt, with cocked-hat and feather. In common a white leather sword-knot is to be worn. Spurs with horizontal rowels to be worn at all times.” Prior to 1812, gaiters and knee-boots had been worn: but on the 14th January in that year his Royal Highness the Prince Regent issued the following order:--
