born c. 1650 - died 1693

In 1688 he followed James II to France. Returned with him to Kinsale the following year. He captured Sligo for the king in 1689 as well as all of Connaght. Not active at the Battle of the Boyne, he retreated to Dublin with James. at this point James retreated to France while Sarsfield and others fled to Limerick. An argument occured there with the two factions disagreeing over whether the city could be defended. Sarsfield believed it could and his side won out. However the opposing faction, led by Lauzune, left for France and took all french troops, their cannon, and their equipment with them. Remaining was the Irish army of some 15,000 who would be facing an army of 40,000 led by william. On 6 June, 1690 Sarsfield left with 600 men and travelled 4 days to come across the supply train following william. The siege train was guarded by only about 100 men. Sarsield openly approached the camp, having learned the password, and attacked when he and his men were right on top of the convoy. They utterly destroyed the supply train. The blaze of all the destroyed weapons could be seen for miles. Sarsfield made his way to limerick, avoiding williams' supporters along the way. His daring victory raised the morale of the army which was now prepared for a siege. A thirteen day siege was rebuffed and Limerick was saved.

Unfortunately the second siege of Limerick in 1691 was more successful for the williamites. After the Treaty of Limerick was signed Sarsfield fled to France and joined the Irish Brigade in the Army of France. He received his death wound with them in 1693 at the battle of Landen. He was carried to Huy where he died a couple days later. Upon seeing his blood from the fatal wound he is supposed to have lamented that it were not shed for Ireland.
