On this day in Tudor history, 15th September 1589, in the reign of Queen Elizabeth I, a battle was fought at Arques in France.
The Battle of Arques was part of the final war of the French Wars of Religion, a series of conflicts in France from 1562-1598 between Catholics and Huguenots. It was a battle between the troops of the new French king, Henry IV, and the troops of the Catholic League led by Charles of Lorraine, Duke of Mayenne.
The battle wasn't looking good for Henry IV, but then everything changed when troops sent by Elizabeth I arrived on the scene.
