In addition, some Royal Irish Artillery gunners were shipped directly to New York under Brigadier-General James Pattison.
The General's papers were reprinted by the New York State Historical Society in 1876, a detailed source of information on this subject.
Pattison, being head of the British Artillery in North America during part of the American Rebellion, had much to say about his Irish.
Yet in spite of all the derogatory remarks, the Royal Irish Artillery was awarded white leather stocks as a mark of their good gunnery.
Buttons from the tunics of the Royal Irish Artillery have been found in Somerville, Massachusetts and upon the site of Fort George at Castin, Maine.
