Used to express allegiance to Ireland, Erin Go Bragh ( Éirinn go Brách in Irish) roughly translates to "Ireland Forever". In 1847 a group of Irish volunteers, including U.S. Army deserters, joined the Mexican side in the Mexican–American War. These soldiers, known as Los San Patricios or Saint Patrick's Battalion, flew as their standard a green flag with a harp on it, with the motto "Erin Go Bragh".
