The rebels had most success in the south-eastern county of Wexford where they seized control of the county, but a series of bloody defeats at the Battle of New Ross, Battle of Arklow, and the Battle of Bunclody prevented the effective spread of the rebellion beyond the county borders. 20,000 troops eventually poured into Wexford and defeated the rebels at the Battle of Vinegar Hill on 21 June. The dispersed rebels spread in two columns through the midlands, Kilkenny, and finally towards Ulster. The last remnants of these forces fought on until their final defeat on 14 July at the battles of Knightstown Bog, County Meath and Ballyboughal, County Dublin.
