I promised some of the French Irish flags a long time ago but here are some at last, those of the regiment Dillon, as carried from 1739-1791:
First raised 1690 from Irish refugees from the campaign in Ireland. In the Irish Brigade in Germany from 1757-1762, according to Susanne's History. Distinguished in the defence of Marbourg February 1761 and at the battle of Vellinghausen July 16th 1761. In various garrisons in France after the war ended.And here is the uniform during the Seven Years War:
(I shall post the flags of Clare and Bulkeley soon; they followed the same pattern but with different colours. I shall eventually post the flags of all the French Irish units at the time of the Seven Years War.)
