The Annals of Ulster has the following entry- "766 Irish: Bellum Sruthre iter H. Briuin & Conmaicniu ubi plurimi ceciderunt di Conmaicnibh, & Aedh Dubh m. Toichlich cecidit.
Dub Innrecht, son of Cathal, was victor".Sruthair ("stream") was identified as Abbeyshrule, near the Inny, in County Longford by O'Donovan.
He considered this the first direct evidence of Ui Briuin expansionism east of the River Shannon.
[1] However Eoin MacNeill said "sruthair" was a common place name, Abbeyshrule was "too far south", and another 'Sruthair' was north-west in the barony of Moydow.
[2] Mac Neill noted Shrule, near Lough Mask, in County Mayo could be the battle site.
