Annals

Annála Connacht^[1]

AC1405.15 Tadc Mac Diarmata, king of Moylurg, made the Airtech expedition to demand the dues of his lordship from the descendants of Conchobar son of Taichlech and from the people of Airtech at large, as has always been the right of a man holding his position. And at Loch Labain in Airtech Mac Diarmata was hard put to it by O Conchobair Donn, the posterity of Muirchertach Muimnech O Conchobair, the sons of Fergal Mac Diarmata, the people of Airtech themselves, the Clann Ceithernaig and the Clann Conchobair. When this excessive body of foes found Mac Diarmata at a disadvantage they made a headlong rush at him, being two or three times as strong as he. They attacked him on two sides (?) and the drovers of O Conchobair, afoot and mounted, charged against him, and each party shot off the volley which was ready in their bows. But Mac Diarmata, with the support of Donnchad Mac Domnaill his constable, Lochlainn Colach Mac Caba and all the new levies of Moylurg, defeated this mingled host of enemies at the beginning p.395 of the day and his men made great slaughter of the rabble. Yet at the end this was a success with failure for Mac Diarmata's people. For some man of the opposing (?) battle sent a woful arrow-shot among the mighty mass of the nobles of the host who were protecting their prince and guarding him from the harm of the slaying; and this arrow passed by the worthless rabble-rout and mean folk and the chief champions of the fight entirely, but the [? point of] the black infernal dart pierced the nape of the prince in sight of all. However, after this irreparable loss, this immitigable misfortune to the free peoples of Sliab Segsa and the warriors of Cnoc in Scail and Tulchan Mailruanaid Moir, which everyone now calls [ {⬌}. . . ], as the poet Mac Coissi says:“Cnoc in Scail was its name at first, from the time of Nera it was his dwelling; the Mound of Maelruanaid of the spearpoints shall be its name until the end of time,” they departed from the country and came to their homes. Tadc was taken to be buried in the tomb of his ancestors, and after the burial of Tadc they made Ruaidri son of Aed Mac Diarmata king, and on my word this was not “a stone for an egg.” This great killing was done on the feast of Crosses, as the chronicler tells us.
