 lord of Banagh took Domhnall's side, along with Ó Baoighill.The opposing forces met near Glencolumbkille, in September 1590, and Domhnall's force was defeated.By 1592 Aodh Ruadh was in power of Tír Conaill and it seems as if Donnchadh was pardoned for opposing him, as Donnchadh was present at Aodh Ruadh's inauguration at Kilmacrenan.
