The flight into exile in 1607 of Hugh O'Neill, 2nd Earl of Tyrone and Hugh Roe O'Donnell, 1st Earl of Tyrconnell following their defeat at the Battle of Kinsale in 1601 and the suppression of their rebellion in Ulster in 1603 is seen as the watershed of Gaelic Ireland. It marked the destruction of Ireland's ancient Gaelic nobility following the Tudor conquest and cleared the way for the Plantation of Ulster. After this point, the English authorities in Dublin established greater control over Ireland, establishing - or, at least, attempting to establish - a centralised government for the entire island, and successfully disarmed the Gaelic lordships. O'Donnell - often known as Red Hugh O'Donnell - died in the archive castle of Simancas, Valladolid, in September 1602, when petitioning Philip III of Spain (1598–1621) for further assistance. His son, Rory, succeeded him as the Earl of Tyrconnell and was active in armies fighting for Madrid in the Low Countries and Spain. He died at the Battle of Barcelona in 1642, a naval engagement against the French fleet.
