<P> The Battle of the Boyne ( Irish : Cath na Bóinne IPA : ( ˈkah n̪ɣə ˈbɣoːn̪jə ) ) was a battle in 1690 between the forces of the deposed King James II of England , and those of Dutch Prince William of Orange who , with his wife Mary II ( his cousin and James 's daughter ) , had acceded to the Crowns of England and Scotland in 1688 . The battle took place across the River Boyne near the town of Drogheda in the east 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 . </P>
