The Battle of Aughrim took place as part of the Williamite War in Ireland, which was a conflict arising from the power struggle between the Protestant King William III of England and the Catholic King James II. Following James II's ousting from the English throne in the Glorious Revolution, he sought to reclaim his dominion and rallied support from Irish Catholics who were loyal to him. The battle, which occurred on July 12, 1691, near the village of Aughrim in County Galway, was characterized by fierce fighting and significant troop movements. William's army, estimated at 25,000 strong, faced off against James' forces, which numbered about 20,000 men. The encounter began with both sides taking strategic positions along the hills and fields surrounding Aughrim, leading to intense combat throughout the day.The key to William's success lay not only in superior numbers but also in his effective use of artillery and cavalry. The battle witnessed brutal hand-to-hand combat with high casualties on both sides, but William's troops eventually outflanked and overwhelmed the Irish defenders. The Duke of Marlborough, a prominent commander under William, played a crucial role in the victory by executing a flanking maneuver that turned the battle in their favor. As the battle concluded, the defeat proved catastrophic for James II's cause and marked the beginning of the end for his efforts to regain the throne in Ireland. The aftermath of Aughrim saw a consolidation of Protestant power in Ireland and set the stage for the Treaty of Limerick, which followed shortly after the battle, formalizing the repercussions of the conflict.
