Patrick Sarsfield (1655-1693), undoubtedly one of the most romantic figures of Irish history, has always captured the popular imagination. This biography describes Sarsfield's unpromising early career where he was dismissed from the army, involved in a series of duels, and took part in two violent abductions of wealthy young widows. His second miltary career began after he had been seriously injured while serving as a volunteer at the battle of Sedgemoor. He survived to become the outstanding Irish soldier in the Williamite War. This book provides a detailed account of that war in Ireland, with special focus on Sarsfield's attack on Sligo, his part in the battle of the Boyne and his celebrated raid on King William's artillery train outside Limerick. Sarsfield's prominent and outspoken part in the politics of the day is evaluated, as are his actions in the final stages of the war at Athlone, Aughrim, and Limerick. His agreement to terms with the Williamites led to the treaty of Limerick. Within two years he died a general in the French army - the most celebrated Irishman of his time.
