He was there in 1690 when the encounter between the Duke of Berwick and Colonel Wolseley took place. He subsequently fought at the Boyne, at Limerick, and at the second siege of Athlone. In 1691 he was Governor of Lanesborough, and when Wauchop, the Governor of the Castle of Athlone, learned that De Ginkell intended to cross, he gave warning to O’Reilly, directing him in case of any danger, to send for the Earl of Antrim’s Regiment, and to drive the English into the river. Colonel O’Reilly accordingly threw up strong works in the only accessible part of the bank at the Connaught side, and De Ginkell’s idea of passing over there was abandoned. At the time of the surrender of Galway (July 1691), he was one of the hostages for its due surrender. After the Capitulation of Limerick, Colonel Edmund and many of his regiment retired with the Irish refugees to France, where he died in 1693.
