During the Nine Years' War, Hugh Roe O'Donnell sought to retake the town of Donegal, which was held by a garrison of English and allied Gaelic troops under Niall Garve O'Donnell, a rival who had sided with the Crown against his kinsman.
From August to September 1601, Hugh Roe O'Donnell's Gaelic Irish army besieged Donegal town. Heavy fighting marked the month-long siege, during which Donegal Abbey was accidentally destroyed by a gunpowder explosion. After suffering several repulses, Hugh Roe O'Donnell failed to take the town and lifted the siege.
Following the failed siege, Hugh Roe O'Donnell marched his army south to Munster to join a Spanish expeditionary force, a move that culminated in the Battle of Kinsale. In his absence, Crown forces used Donegal as a base to capture the strategically important town of Ballyshannon.
