 There is a suggestion that this conflict resulted in the Battle of Cúl Dreimhne in Cairbre Drom Cliabh (now in County Sligo) in 561, during which many men were killed.Richard Sharpe, translator of Adomnán's Life of St. Columba (referenced in the bibliography below) makes a stern caution at this point against accepting the many references that link the battle and Columba's leaving of Ireland, even though there is evidence in the annals that Columba supported his own king against the high king.Political conflicts that had existed for some time resulted in the clan Neill's battle against King Diarmait at Cooldrevny in 561.
