In 1691, at the end of the Williamite War in Ireland, the Irish Jacobites soldiers who had fought hard for a free Catholic Ireland (against the British Protestants) and lost, were allowed to leave Ireland with their weapons and sail to France under the terms of the Treaty of Limerick.
14,000 brave soldiers, who would rather fight a war for another country than remain under British rule, would make that journey - joined by 10,000 women and children. This event is known in Ireland as the Flight of the Wild Geese, for at the time those soldiers believed they would one day make the trip back to their homeland and fight in a battle to free it once more.
While waiting for their day of return those soldiers changed the course of history in many countries, here is a small clip of their impact, felt even today.
Recently a new Irish Whiskey was released named in honor of The Wild Geese.
