The Volunteers of Ireland were a Loyalist unit during the American Revolution. The regiment was designed to appeal to Irishmen—particularly those from the Continental Army. The Volunteers of Ireland wore green facings, carried an Irish harp on their cap, and marched to a song called “Success to the Shamrogue.” (see https://redcoatsandruffles.blogspot.com/2016/03/happy-saint-patricks-day-from.html) The regiment, which had been given the title of the 2nd American Regiment in 1779, was shipped to South Carolina in 1780 to aid Sir Henry Clinton in his siege of Charleston.
Their uniform is a short red coat with green brandenbourgs and a light infantry cap with an Irish harp. I love this particular combination, as it is so unusual and dashing!
Figures by BMC. The soldier loading his musket is a conversion. They are painted with Testors paints.
