Battle of Landen
"Jackets green" is a joking statement by Irish people for any disaster, as is "down the glen", meaning lost and hopeless. Sarsfield himself, one of those thousands of Irish aristocrats and others who took service in the armies of Europe, died fighting for James II/VII's patron Louis XIV of France at the Battle of Landen in Flanders, exactly three years later, on 19 August 1693; as his life's blood flowed away he was heard to cry "Would that this blood were shed for Ireland".
