Some of the debentures issued to the creditors of the English Ordnance, in lieu of money, were on security of the grounds in the City of London, called the Artillery Grounds, and carried interest at the rate of two per cent.: others were merely promissory notes issued by the Board, which bore no very high reputation, nor were they easily convertible into money. From certain correspondence in the Tower Library, during the reigns of Charles II. and James II., it would appear that the Board could not be sued before the Law Courts for the amount of their debts;—the letter-books of that period teeming with piteous appeals from the defrauded creditors.
One unhappy man writes that in consequence of the inability of the Board to meet his claims, he "had undergone extreme hardships, even to imprisonment, loss of employment, and reputation." Another in the same year, 1682, writes, that "he is in a very necessitous and indigent condition, having not wherewithal to supply his want and necessity; and he doth in all humility tender his miserable condition to your Honours' consideration."
During periods of actual or expected disturbance in Ireland, stores for that country were often accumulated in Chester, and on the Welsh coast, ready for shipment; from which it may be inferred, that the arrangements in Ireland for their safe keeping were inadequate.
The formation of a battalion of Artillery on the Irish establishment was not contemplated until the year 1755, when, on the requisition of the Lord-Lieutenant, a party of twenty-four non-commissioned officers and men of the Royal Artillery, under the command of a First Lieutenant, left Woolwich for Dublin, for that purpose. This detachment, having received considerable augmentation and a special organization, was in the following year styled "The Artillery Company in Ireland," the commissions of the officers being dated the 1st of April, 1756. The company consisted of a Major, a Captain, one First and one Second Lieutenant, three Lieutenant-Fireworkers, five Sergeants, five Corporals, one hundred and six Bombardiers, thirty-four Gunners, one hundred and two Matrosses, and two Drummers. The large number of Bombardiers suggests a special service, probably in the bomb-vessels, for which this class was employed. Major Brownrigg, the commandant of the corps, was replaced in 1758, by Major D. Chevenix, from the 11th Dragoons. Two years later, the company was considerably increased, and was styled the "Regiment of Royal Irish Artillery." It had now a Colonel-in-Chief, and another en seconde, a Lieutenant-Colonel commandant, a Major, four Captains, four First and four Second Lieutenants, and four Lieutenant-Fireworkers. The Masters-General of the Irish Ordnance were ex officio Colonels-in-Chief of the Irish Artillery. The following is a list of those who held this appointment during the existence of the corps: James, Marquis of Kildare, Richard, Earl of Shannon, Charles, Marquis of Drogheda, Henry, Earl of Carhampton, and the Hon. Thomas Pakenham.
Reductions were made in the Regiment at the conclusion of peace in 1763, and again in 1766; but they were chiefly confined to weeding the Regiment of undersized men. In 1774, the rank of Lieutenant-Fireworker was abolished, three years later than the same change had been made in England. In 1778, the Regiment was augmented from four to six companies, the total of the establishment being raised from 228 to 534; and from that date the senior first lieutenant received the rank of Captain-Lieutenant. A further addition of seventy-eight gunners raised the total to 612, and caused an increase in the number of officers, four Second Lieutenants being added in 1782.
In August, 1783, an invalid company was added, consisting of a captain, first and second lieutenant, one sergeant, two corporals, one drummer, three bombardiers, four gunners, and thirty-nine matrosses, and with a few additions to the marching companies raised the establishment to 701. But in three months, a most serious reduction can be traced, not in the cadres, nor among the higher commissioned ranks, but among the subalterns, and the rank and file, and the total fell to 386.
By the monthly returns for October, 1783, we find that the title of matross, although retained in the invalid company, was otherwise abolished; the private soldiers being now all designated gunners. From 1783 to 1789, the establishment remained at 386; and in 1791, it was the same. The returns for the intermediate year have been lost.
In 1793, recruiting on a large scale can be traced, and we find, that in October, 1794, by successive augmentations, the establishment had reached a total of no less than 2069 of all ranks, organized into one invalid and twenty marching companies. By a King's letter, dated 20th May, 1795, these were constituted into two Battalions, the company of invalids remaining distinct. This gave an addition of thirteen Field and Staff Officers, and three Staff Sergeants, raising the total establishment from 2069 to 2085. Each company consisted of 100 of all ranks—except the invalid company, which remained at a total of fifty-three, until 1st October, 1800, when it was raised to 100—and the strength of the Regiment reached its maximum, 2132.
This establishment continued, until the 1st of March, 1801, when, in anticipation of the amalgamation with the Royal Artillery, eight companies, with a proportion of Field Officers, were reduced, followed next month by a reduction of two more.
On the 1st April, 1801, the remaining ten marching companies, with Field and Staff Officers, were incorporated with the Royal Artillery, and numbered as the 7th Battalion of that corps. By General Order of 17th September, 1801, the invalid company was transferred to the battalion of invalids on the British establishment.
