Ongoing conflict between Hiberno-Norman Crown forces and the Gaelic MacGeoghegan clan of Cenel Fiachaigh in the Irish midlands led Thomas Butler to mount an assault on the fortified settlement of Ardnurcher, seeking to assert Norman control over the region in the early fourteenth century.
On 10 August 1329, Crown forces under Thomas Butler attacked the fort of Ardnurcher, present-day Horseleap in County Westmeath. They were repulsed by William Gallda MacGeoghegan. According to the Annales Hiberniae, Butler and several high-ranking officers were killed along with 140 soldiers; the Annals of the Four Masters records the Norman dead at 3,500.
The Norman forces suffered a decisive defeat, with their commander Thomas Butler killed alongside numerous followers. The outcome demonstrated the continued military capacity of Gaelic Irish lords to repel Crown incursions in Westmeath and underscored the limits of Norman authority in the Irish interior during this period.
