In this battle Diarmait is stated to have employed druids to form an airbe druad (fence of protection?) round his host.
A few years later Diarmait seized by force the chief of Hy Maine, who had slain his herald and had taken refuge with St Ruadan of Lothra.
But Diarmait pursued him, and disregarding the opposition of the saint seized Curnan and hanged him.
Diarmait MacMurchada (Dermod MacMurrough), greatgrandson of Diarmait Mael-na-mBo, as king of Leinster was by descent and position much mixed up with foreigners, and generally in a state of latent if not open hostility to the high-kings of the Hy Neill and Dalcais dynasties.
