The Battle of the Boyne: Why Is It Really Celebrated on the Twelfth?

When Pope Alexander VIII heard a Protestant king had just won a battle in Ireland, he ordered the bells of the Vatican rung in celebration. This is the real story of the Battle of the Boyne — far stranger, and far more international, than the simple Catholic-versus-Protestant story most people know. A king nearly killed by a cannonball the day before the fight. A veteran commander cut down in the crossing. A defeated rival king who fled so fast his own supporters gave him a nickname that outlived his entire reign. And a date — the Twelfth of July — that only means what people think it means because of a calendar reform sixty years later.
