On 16 February 1595, a Gaelic Irish force assaulted and captured the English-held Blackwater Fort at Blackwatertown in County Armagh. The Irish were led by Art MacBaron O'Neill, brother of Hugh O'Neill, Earl of Tyrone, and marked Tyrone's break with the English Crown as he openly waged war against the English forces in Ireland.
