The Plantation of Ulster continued well into the 18th century, interrupted only by the Irish Rebellion of 1641. This Rebellion was initially led by Sir Phelim O'Neill (Irish: "Sir Féilim Ó Néill"), and was intended to overthrow British rule rapidly, but quickly degenerated into attacks on colonists, in which dispossessed Irish slaughtered thousands of the colonists. In the ensuing wars (1641–1653, fought against the background of civil war in England, Scotland and Ireland), Ulster became a battleground between the Colonialists and the native Irish. In 1646, an Irish army under command by Owen Roe O'Neill (Irish: "Eoghan Ruadh Ó Néill") inflicted a defeat on a Scottish Covenanter army at Benburb in County Tyrone, but the native Irish forces failed to follow up their victory and the war lapsed into stalemate. The war in Ulster ended with the defeat of the native army at the Battle of Scarrifholis, near Newmills on the western outskirts of Letterkenny, County Donegal, in 1650, as part of the Cromwellian conquest of Ireland conducted by Oliver Cromwell and the New Model Army, the aim of which was to expel all native Irish to the Province of Connaught.
