There is still some uncertainty concerning the location of the battle. The "Annals of Ulster" report that "Sitriuc, grandson of Ímar, landed with his fleet at Cenn Fuait on the border [, "airer"] of Leinster." No such place is known, but the "Annals of the Four Masters" record that the battle took place in "the valley above Tech Moling". Tech Moling is St Mullin's, an ecclesiastical settlement in the extreme south of County Carlow, on the western boundary of Leinster, and accessible by ship via the River Barrow. Edmund Hogan identified Cenn Fuait ("Fuat's Head") with Glynn, a village which lies on a small stream about a kilometre north-east of St Mullin's.
