Irish regiments served in the War of the Austrian Succession, Seven Years' War, both in Europe and India, and during the American War of Independence, though by the 1740s the number of Irishmen serving in the regiments had begun to markedly decline. The five regiments were increased to six during the War of the Austrian Succession, the sixth being Lally's, initially created by the Comte de Lally -Tollendal through drafts from the original five. Each regiment had a strength of one battalion of 685 men and Fitzjames's cavalry regiment counted 240 men. The Brigade played a crucial role at Fontenoy attacking the right flank of the British column suffering 656 casualties and, according to O'Callaghan captured the colours of the Coldstream Guards and fifteen cannon. McGarry, in a recently published book entitled "Irish Brigades Abroad", identifies the flag concerned coming from Sempill's Regiment of Foot, the forerunner of the King's Own Scottish Borderers. The Irish suffered even higher casualties of around 1400 men, at the Battle of Lauffeld when they led the assault which drove the British from Lauffeld village and secured victory. During the Seven Years' War the Irish Regiments in French service were: Bulkeley, Clare, Dillon, Rooth, Berwick and Lally as well as one regiment of cavalry (Fitzjames's).
