Diarmait overcame Connaughtmen till he came to Aidne. Guare gathered to him the men of Munster. These were the kings that came to succour Guare, to wit, Cuan, son of Enna, king of Munster, and Cuan, son of Conall, king of Húi Fidgenti, and Tolomnach, king of Húi Liatháin. The battle of Carn Conaill was fought between them on the day of Pentecost, and Guare was defeated, and a 'slaughter of chiefs' was inflicted there, including Cuan, son of Enna, king of Munster, and Cuan, son of Conall, king of Húi Conaill, and Tolomnach, king of Húi Liatháin.
