The army left Áth Cúile Feá and continued their march, setting up camp that night in Emly (Druim Meáin Mairtine / Ardchluain na Féne / Mucfhalach Mac Dáire Ceirbe)

Cith Mór meets Meadhrán, the Druid of Meán Mairtine.

Cith Mór left the camp and headed southwest where he met Meadhrán, the Druid of Meán Mairtine. Cith Mór told the druid that they were heading for Cnoc na gCeann / Droim Dámhgháire the following day. Meadhrán wished the same evil on Cormac’s army that they intended for the army of Fiachra.

From Emly, Cormac's army could have gone directly to the Hill of Knocklong, crossing the Camoge River. Since the fifteenth century, the castle on the Hill is visible from Emly.
