Garret Barry, also called Gerat (died 1646), was an Irish soldier and military writer, who fought for Spain in the Eighty Years' War and then for the Irish insurgents in the Rebellion and the Confederate Wars. When young he left Kinsale at its surrender in 1602 for Spain where he took service, first as marine in the Atlantic Fleet and then in the Army of Flanders. While in Spanish service, he fought at the Siege of Breda in 1624/1625. He retired with the rank of captain in 1632. Returning to Ireland he was at the Rebellion appointed general of the insurgents' Munster Army. He took Limerick in June 1642 but was defeated at Liscarroll by Inchiquin in September. He was confirmed as General of the Munster Army by the Irish Catholic Confederation but was in practice superseded by Castlehaven in 1643. Birth and origins Garret was probably born near the end of the 16th century. and is probably the 'Garrot Barry', eldest of the four sons of 'David FitzGarret Barry', 'dwelling at Rincorran', who is mentioned in Pacata Hibernia in the context of the Siege of Kinsale, Munster, Ireland in 1602. Rincurran, also spelled Rincorran, is a locality near Kinsale. Rincurran Castle stood where Charles Fort, built in 1677, now stands. It was also called Barry Óg's Castle as it belonged to the Barry Óg (younger) branch of the de Barrys. Garret's father was a member of a cadet branch of the De Barrys, possibly the Barry Ogs. The de Barrys were a landed Old English family, seated in County Cork. During most of Barry's life, first David de Barry, 5th Viscount Buttevant and then David Barry, 1st Earl of Barrymore were heads of the family. Unlike Barry, both sided with the government. Siege of Kinsale Tyrone's Rebellion, also called the Nine Years' War in Ireland was a theatre of the Anglo-Spanish War (1585–1604), as a Spanish expeditionary force under Juan del Águila landed at Kinsale end September 1601 Old Style (O.S.). Águila garrisoned Rincurran Castle. Charles Blount, 8th Baron Mountjoy, Deputy of Ireland, rushed down to Munster and started the siege early in October. He took Rincurran Castle in November. After Tyrone's defeat at the battle of Kinsale in December and the surrender of Kinsale in February 1602, Barry, in company of his parents and three brothers, was allowed to leave Ireland together with the Spanish in March 1602.
