Jacobite earl of Lucan. Born to a catholic family, Sarsfield entered the Irish army in 1678. He then served in the English regiments which Charles II detached to fight in the army of Louis XIV of France, but returned to England at the succession of James II in 1685, and helped to crush Monmouth's rising. Sarsfield commanded the Irish troops in England in 1688, but fled to France with James, returning with him to Ireland in 1689.
In the war that followed Sarsfield rose rapidly to major‐general. His attacks on Williamite supply lines forced the raising of the first siege of Limerick but, after defeat at Aughrim, he concluded the second siege of Limerick on terms which allowed him to sail for France. He was mortally wounded at the battle of Landen.
