The Clare's Regiment, later known as Clare's Dragoons, was initially named O'Brien's Regiment after its originator Daniel O'Brien, 3rd Viscount Clare raised a mounted dragoon regiment during the Jacobite war. When Clare's Dragoons left Limerick with the Flight of the Wild Geese they became a regiment of infantry. Clare's Dragoons remained loyal to the dethroned James II of England and fought against the army of William III of England, during the Williamite War in Ireland.
