Patrick Sarsfield(c.1650s)
Patrick Sarsfield was a late seventeenth century Irish soldier from a Munster gentry family who became the most prominent Irish cavalry commander in the Williamite War in Ireland. Born about 1655, he remained a committed Roman Catholic during an age of confessional conflict and rose by service and personal energy into command among the Irish horse. He first attracted wider notice in operations across Ulster and Connacht and then returned towards Munster where his energy and reputation made him a central figure at Limerick. Contemporaries described him as daring, practical and willing to use surprise against better equipped enemies frequently.
During 1690 Sarsfield argued strongly for holding Limerick as the last great defensive position west of the Shannon. After the Jacobite defeat at the Boyne on 1 July 1690 many senior officers favoured retreat or surrender, but Sarsfield, the French commander the Duke of Berwick and Governor Boisseleau insisted that Limerick controlled river communications and stores and could yet sustain resistance. He organised cavalry patrols, counterattacks and local reconnaissance. His leadership helped steady the garrison during William of Orange’s approach and contributed to the refusal of an early surrender demand before the first siege in August 1690 and local morale.
The most famous exploit associated with Sarsfield was the destruction of a Williamite siege train intended for Limerick. Using intelligence, mounted raiders and surprise he led an attack on the convoy before it reached the city and destroyed its heavy artillery and ammunition. That action relieved immediate pressure upon the defences, became celebrated across Ireland and is still remembered locally as an example of daring initiative. Despite such successes the strategic balance favoured Williamite operations. The campaign continued, supplies were strained and by 1691 the situation compelled renewed negotiations and eventual terms agreed by both sides with limited favourable guarantees.
In October 1691 Sarsfield acted for the Jacobite military interest during the negotiations which ended organised resistance in Munster and Connacht. Under the articles later known as the Treaty of Limerick the Irish army were permitted to go abroad into French service rather than disperse at home. Sarsfield accepted exile as the only feasible way to preserve core units and to keep hope alive for a future restoration. He left Ireland with many officers and men in the movement described as the Flight of the Wild Geese and entered the service of Louis XIV, taking commission in the French army.
In exile Sarsfield continued to serve as a soldier and as a Catholic cause celebrity until his death in 1693. He fought with Irish regiments in Flanders and was promoted in the French service before his last action. He fell mortally wounded at the battle commonly called Landen or Neerwinden in July 1693 and died soon afterwards. Back in Limerick his memory was preserved in local tradition, songs and later histories which stress his role in defending the city and destroying the siege train. His life links Munster gentry, Catholic loyalty and the international dimensions of seventeenth century warfare memory.
