Brian’s Northern Test
The firmest and most dramatic event of the year is the battle of Cráeb Tulcha. The Annals of Ulster date it precisely to Thursday, 14 September, and describe it as a battle between the Ulaid and Cenél nEógain. The Ulaid were defeated, and their losses were severe. Eochaid son of Ardgar, king of Ulaid, fell with members of his close kindred, including Dub Tuinne and two sons of Eochaid. The annal also names other leaders among the dead and says that the fighting and rout extended as far as Dún Echdach and Druim Bó.
