At this time, H.R.H. the Duke of York ordered two 12-pounder guns to be attached to each troop of Horse Artillery, and, as will be seen hereafter, these guns remained part of the armament of the troop of Horse Artillery which formed part of the expedition to the Helder, in 1799. Two guns, from four troops respectively, went to Ireland to assist in quelling the rebellion, but only those belonging to A, B, and C Troops took part in the active operations. The strength of the Horse Artillery sent to Ireland was as follows:-- [Sidenote: Embarkation Returns, dated Woolwich, 26 Nov. 1797.] 2 Captains. 3 Subalterns. 1 Assistant-Surgeon. 2 Staff-Sergeants. 12 Non-Commissioned Officers. 92 Gunners. 51 Drivers. 6 Artificers. 1 Trumpeter. 177 horses (and 13 from Driver Corps). 8 guns. 15 ammunition waggons. N.B.--The guns were two 12-pounders, two 5½-inch howitzers, four 6-pounders. The total strength of Horse Artillery left in England was as follows: 968 of all ranks, 920 horses, 42 guns, and 72 waggons. This included a reserve of 5 guns at Woolwich. After the rebellion had been quelled, the men of the Royal Artillery, who during the operations had been under the Irish Branch of Ordnance, returned to England; and the following table gives the distribution and strength of the Royal Irish Artillery in the succeeding year. (_See_ pp. 80 and 81.) Returning to England, the student will find not a few matters of domestic interest which occurred during this period, and which are worthy of being chronicled. A new organisation of the Ordnance Medical Department took place; and on a recommendation of a committee it was [Sidenote: B. O. Proceedings, 5 May, 1797.] resolved, on the 5th May, 1797, that, after the 1st July following, the system of obliging surgeons to furnish the medicines for the troops out of a fixed money allowance should cease, and that one of the Ordnance chemists should be appointed Regimental apothecary. An increase of pay was also granted to the medical officers. DISTRIBUTION of the ROYAL IRISH REGIMENT of ARTILLERY, October 1799. INDEX. A. Lieut.-Colonels. B. Majors. C. Captains. D.
