HiThe Shule Aroon version, (basically the same as the others), tells of a woman's love for a soldier who has fled to France after the final surrender in 1691 of the Catholic armies to William of Orange's Protestant forces at Limerick in Ireland.
These soldier's were known as "The Wild Geese", and fought for Ireland in the armies of France and Spain.
Hope this helps.
