It was a singular coincidence that the officer of the Royal Artillery, who forty-six years before had left Woolwich to organize the first company of the Royal Irish Artillery, should, on the amalgamation, have been the Colonel commandant of the new Battalion. Lieutenant-General Straton had proceeded, in May, 1755, to Ireland, for the former purpose, and he rejoined the Royal Artillery on the 1st April, 1801, as Colonel commandant of the 7th Battalion. He died in Dublin on the 16th May, 1803, after a service of sixty-one years.

At the time of the amalgamation, six of the companies were stationed in Ireland, and four in the West Indies. The Irish Artillery was not exempt from foreign service, and the conduct of the men abroad was as excellent as it always was during the times of even the greatest civil commotion. When, however, they left Ireland on service, their pay became a charge on the English Office of Ordnance; and in the Returns from their own head-quarters we find that any men who might be in England, pending embarkation, were shown as "on foreign service."

The first employment of the Irish Artillery abroad was during the American war. In March, 1777, seventy men embarked, under the command of an officer of the Royal Artillery, and did duty with that corps in a manner which called forth the highest commendations from the officers under whom they served. The Master-General of the Ordnance, Lord Townsend, in a letter to the officer commanding the Irish Artillery, dated 23rd of December, 1777, alludes to these men in the following terms: "I am informed that none among the gallant troops behaved so nobly as the Irish Artillery, who are now exchanged, and are to return. I am sorry they have suffered so much, but it is the lot of brave men, who, so situated, prefer glorious discharge of their duty to an unavailing desertion of it."

The conduct of the Irish Artillery, both in America and in the darkest period of their service, in the West Indies, contrasts so strongly with that of the men enlisted in Ireland for the Royal Artillery at the same time, that evidently the recruiting for the latter corps must have been grossly mismanaged, or, what is more probable, the national corps obtained with ease the best men, while the refuse of the country was left to the recruiting sergeants of the Royal Artillery. In the correspondence of General Pattison, who at one period of the American war commanded the Royal Artillery on that continent, the language employed in describing the recruits enlisted in Ireland, and sent to join the 3rd and 4th Battalions in America, would be strong in any one, but is doubly so, coming from an officer always most courteous in his language, and by no means given to exaggeration.

Three companies of the Irish Artillery embarked for the Continent in 1794, and served in Flanders and the Netherlands, under the Duke of York. But, as has already been hinted, the most severe foreign service undergone by the corps was in the West Indies. In 1793, three companies embarked for these islands, and took honourable part during the following year, in the capture of Martinique, Guadaloupe, and St. Lucia, as well as in the more general operations.

Their strength, on embarkation, had been 15 Officers and 288 non-commissioned officers and men. In less than two years, only forty-three of the men were alive, and of the officers, only four returned to Europe. It accordingly became necessary to reinforce the companies by drafts from Ireland; and in addition to these, two other companies sailed in the winter of 1795; thus bringing the total strength serving in the West Indies to 500 of all ranks. In less than two years, a further reinforcement of 176 officers, non-commissioned officers, and men, was found necessary to repair the ravages of the climate upon the troops; and apparently further drafts in the following year were only avoided, by transferring the head-quarters of one of the companies to the home establishment, and absorbing the men in the others. Four of the companies were still in the West Indies, when the amalgamation took place.

Certain details connected with the organization of the Irish Artillery, immediately prior to their incorporation with the Royal Artillery, remain to be mentioned. On the 19th September, 1798, Lord Carhampton, then Master-General of the Irish Ordnance, notified to the officer commanding the corps, that the formation of the Artillery in Ireland into Brigades had been decided upon; the Brigades to be distinguished as heavy and light. The establishment of a Heavy Brigade was to include four medium 12-pounders, and two 5½-inch howitzers:—of a Light Brigade, four light 6-pounder Battalion guns. The former was to be manned by forty-eight non-commissioned officers and men, the latter by thirty-seven—of the Regiment; while the guns and waggons were to be horsed and driven by the Driver Corps. This improved organization superseded the system of Battalion guns; for while, in September, 1798, one hundred of the Irish Artillery were returned as being attached to these, in November only thirty-seven were so employed; in the following January, only four; and in March, 1799, all were finally withdrawn. The additional gunners from the Militia, who had, at the date of the new organization, been 213 in number, were gradually reduced by its operation, and in the monthly return for September, 1799, they disappear altogether.

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."
