Claim: King Domnall Brecc of Dál Riata's name first appears on the Annals of Tigernach in 622 with the winning side during the batte of Cend Delgthen as ally of Clann Cholman, also the only battle he is known for winning considering he later suffered four defeats after he broke alliance with clan Uí Néill.
Evidence: Domnall Brecc (Welsh: Dyfnwal Frych; English: Donald the Freckled) (died 642 in Strathcarron) was king of Dál Riata, in modern Scotland, from about 629 until 642. He first appears in 622, when the Annals of Tigernach report his presence at the battle of Cend Delgthen (probably in the east midlands of Ireland) as an ally of Conall Guthbinn of Clann Cholmáin. This is the only battle known where Domnall Brecc fought on the winning side. Domnall suffered four defeats after he broke Dál Riata's alliance with the Cenél Conaill clan of the Uí Néill.
