Battle of Belahoe
The Battle of Belahoe or Ballyhoe (Irish: Béal Átha hÓ) was fought in 1539 between the O'Neills and O'Donnells against English forces, in which the O'Neills and O'Donnells were defeated. The battle occurred while the Lord Deputy of Ireland, Leonard Grey, was mounting an armed tour around Ireland to secure the submission of the allies of the Fitzgeralds of Kildare, who had recently been in rebellion against the Crown. While Grey was in the south at Cork, a raid was undertaken into Meath by the Fitzgeralds' allies, O'Neills, led by Conn O'Neill, and the O'Donnells, led by Manus O'Donnell into the English Pale, around Dublin. They destroyed and looted the towns of Ardee and Navan, before English forces in the Pale could be mobilised. However, the Lord Deputy of Ireland, Leonard Grey, returned with a force of about 800 men to oppose them.
