It was at first proposed that the 12-pounders and the howitzers of the Heavy Brigades should be drawn by four horses, and the 6-pounders of the Light Brigades by three; but subsequently a 4½-inch howitzer having been added to each Light Brigade, the number of horses to each gun was apparently increased from three to four, and the total number of horses to each Heavy Brigade was seventy-three;—to each Light Brigade, fifty- one. The "two leading horses were ridden by Artillerymen, and the gun was driven by a driver."[16] This arrangement applied also to the ammunition waggons. The harness-maker, wheeler, and smith, each rode a spare horse with harness on. While the guns had four horses, the howitzers in Heavy Brigades had but three, and in Light Brigades only a pair. The Driver Corps furnished to each Heavy Brigade 1 officer, 1 quartermaster, 3 non-commissioned officers, and 26 privates; to each Light Brigade, 5 non-commissioned officers and 14 privates. For the information of the general reader, it may be stated that the Brigades of the Irish Artillery were analogous to the present Field Batteries; the modern Brigade of Artillery meaning a number of Batteries linked together for administrative purposes. In January, 1799, there were twenty-five Brigades in Ireland, and at this point they remained until the amalgamation with the Royal Artillery. Although it is not probable that they were all horsed at that date, there were no less than 1027 officers and men at the appointed stations of the Brigades, and in the language of an old document in the Royal Artillery Record Office, "the New Irish Field Artillery had not only form, but consistency." In addition to these Brigades of Field Artillery, the Regiment was divided into detachments—generally eight in number,—stationed in the chief harbours, garrisons, and forts, for service with heavy ordnance. The invalid company was scattered over the country, many of the non- commissioned officers and men being totally unfit for service. The Regiment was actively employed in the field during the Rebellion; "and it must be recorded to the honour of the Royal Irish Regiment of Artillery, that though exposed to every machination of the disaffected, and to the strongest temptations, they preserved throughout an unsullied character, and manifested on all occasions a true spirit of loyalty, zeal, and fidelity to His Majesty's service and Government."[17] The dress of the Royal Irish Artillery was as follows:—Blue coat with scarlet facings, cuff and collar gold embroidered; yellow worsted lace being used for all beneath the rank of corporal; gold-laced cocked hat, black leather cockade, white cloth breeches, with short gaiters and white stockings in summer, and long gaiters in winter. The non- commissioned officers and men wore their hair powdered and clubbed. In 1798 jackets were introduced according to the pattern adopted for the Army; and the gold lace was removed from the cocked hats.
