Kalends of Jan. (on 3rd feria, 21st of the moon,) A.D. 1247.
Mael-Sechlainn Ua Domnaill, king of Tir-Conaill, and the Wry-necked Gilla Ua Baighill and Mac Somairligh were killed by Fitz Maurice in Bel-Atha Senaigh. And the Cenel-Conaill held the Ford for an entire week, so that they allowed neither Foreigner nor Gaidhel across, until Cormac Ua Conchobair played a ruse in the end. That is, Cormac went with the horse host throughout the length of the plain westwards and he turned after that upwards, throughout the length of the same plain, to the edge of the morass and went close thereby eastwards, until he reached the Ford of Cuil-Uaine on the Erne. And the Cenell-Conaill noticed not until they saw the great horse-host advancing to them, on the side of the river on which they were. And whilst the Cenel-Conaill had their attention upon the horse-host on their rear side; the Foreigners plunged into the Ford, so that the Cenel-Conaill and the Wry-necked Gilla Ua Baighill and Mac Somairligh met Fitz Maurice in Bel-Atha-Senaigh and fell there.
