The Flight of the Wild Geese refers to the departure of an Irish Jacobite army under the command of Patrick Sarsfield from Ireland to France, as agreed in the Treaty of Limerick on 3 October 1691, following the end of the Williamite War in Ireland. More broadly, the term "Wild Geese" is used in Irish history to refer to Irish soldiers who left to serve as mercenaries in continental European armies in the 16th, 17th and 18th centuries.
