Seltanahunshin (Irish derived place name, either Sailtean na hUinseann meaning 'The Wood of the Sallows and Ash Trees' or Sailten na n-Gasán meaning the 'Sally-Wood of the Paths') is a townland in the civil parish of Oughteragh, barony of Carrigallen, County Leitrim, Ireland.
And they came to Achadh-Conaire, and despatched messengers from thence to Muinter-Raighilligh, and requested them to come to meet them to Cros-Doire-chaein, at the eastern end of Brat-sliabh in Tir-Tuathail.
:—Friday in particular, and the festival of the Cross above all days, that Conchobhar, son of Tighernan O'Ruairc, mustered the men of Breifne and the Conmaicne, and as many as he could secure along with them, including Aedh O'Conchobhair and the nobles of Connacht, and the Síl-Muiredhaigh besides.
Then the great army came up with them, after some of their people had been slain, along with Diarmaid O'Flannagain, and Mac Maenaigh, and Coicle O'Coicle, and many more; and these several armies all marched to Alt-na-hélti (The Height of the Doe), and to Doirin-cranncha, between Ath-na-beithighe and Bél-in-bhealaigh, and between Coill-essa and Coill-airther on Sliabh-an-iarainn, where Muinter-Raighilligh turned sternly, earnestly, furiously, wildly, irrepresibly, against the son of Fedhlim and all the Connachtmen who were along with him, to avenge upon them their wrongs and oppressions; and each party then incited their people against the other, i.e. the battalion of the Uí-Briuin and the Connachtmen.
And a brave, destructive, heroic battle was fought between them respectively in that hour; and multitudes were killed and wounded, here and there, on both sides.
They came to Mayo and Balla and passed through Leyney, which they plundered on all sides, to Achonry; and from there they sent messengers to the Ui Raigillig, bidding them to come and meet them at Cros Dairi Cain at the eastern end of the Brauslieve mountains in Tir Thuathail.
The Ui Raigillig came to Clachan Mucada on Slieve Anierin, but turned back from there, not having effected a meeting with the Galls, and came to Soltin Gasain.
The van of this host came upon the Ui Raigillig at Sailten Gassan and pursued them to Alt Tige Meg Currin.
The main army came up with them after [some of] their men had been killed: Diarmait O Flannacain, Mac Maenaig, Coiclid O Coiclid and a number of others; and the combined armies came to Alt na hElti and Doirin Cranncha, between Ath na Betige and Bel in Belaig and Coill Esa and Coill Airthir, on Slieve Anierin.
And here the Muinter Raigillig turned hardily, eagerly, wildly, strenuously, irrepressibly, to attack Fedlim's son and to avenge their injuries and oppression on him, and each chieftain exhorted his followers to go against the Connacht army.
However, those who have knowledge of this great battle relate that the warriors of the host on that field could not look in the face of the high lord, for two great wideglancing torches were flaming and flashing in his head, so that all feared to speak with him; for he was within hailing-distance in front of the armies as they approached the forces of the Ui Briuin; and he uttered his high-king's war-cry and his champion's shout in the midst of the fight and never stopped on that charge and onset until the ranks of the Ui Briuin were scattered.
Namely, those killed were Cathal and Domnall and Cu-Connacht and the Blind Gillie and Geoffrey Ua Raghallaigh and all the nobles of Muinnter-Raghallaigh and the Ui-Briuin on one spot at Allt-na-heillti, over Belach-na-Beithighe, in front of Sliabh-in-iarainn.
