In 629, the Dal nAraide appear to have defeated the Dál Riata at Fid Eóin, killing Connad Cerr, although the victor is named as Maél Caích, perhaps an otherwise unknown brother of Congal. As well as their king, the Dál Riata suffered the loss of two grandsons of Áedán mac Gabráin and the Bernician exile Osric (perhaps a son of Æthelfrith) was also killed. It is possible that upon becoming King of Ulaid, Congal resigned the affairs of Dal nAraide to Maél Caích mac Scandail who met opposition from other Criuthne led by Dícuil mac Echach who may have been a member of the Latharna of Larne (a Dal nAraide tribe).
