About: Battle of the Boyne

The Battle of the Boyne took place in 1690 between the forces of the deposed King James II, and those of King William III who, with his wife Queen Mary II, had acceded to the Crowns of England and Scotland in 1689. The battle was fought across the River Boyne close to the town of Drogheda in the Kingdom of Ireland, modern-day Republic of Ireland, and resulted in a victory for William. This turned the tide in James's failed attempt to regain the British crown and ultimately aided in ensuring the continued Protestant ascendancy in Ireland. The battle took place on 1 July 1690 O.S. William's forces defeated James's army, which consisted mostly of raw recruits. Although the Williamite War in Ireland continued until the signing of the Treaty of Limerick in October 1691, James fled to France after the Boyne, never to return.
