MACFADYEN came from Ireland (Eirin) to Cantyre (Cinn-tìre), with a following of 1400 men, to assist King Edward in his efforts to conquer Scotland. From Cantyre he made his way to Lorne (Lathurna), where he was joined by a party of the MacDougalls. When the Knight of Lochow (Loch-odha) heard of his coming, he sent a messenger to inform Sir William Wallace of it, who was at the time in Perthshire (Siorramachd Pheairt). Sir William was not slow in marching to meet the enemy. The two hosts encountered each other in the Pass of Awe (Atha). MacFadyen and his men were defeated and routed. He, and as many of his officers as escaped with him, hid themselves in a cave in the face of a rock called Creag-an-aoinidh. Sir William sent the Knight of Lochow and a party of men in pursuit of the fugitives; and having found them in the cave, they cut off their heads, and placed them on stakes on the top of Creag-an-aoinidh. This cave is called MacFadyen’s Cave to the present day.
The battle between Wallace and MacFadyen took place in 1300.
Makfadyane fled, for all his felloun stryff
On till a cave, within a clyfft of stayne
Wnde Cragmore, with fyftene is he gayne
Dunkan off Lorn his leyff at Wallace ast;
On Makfadyane with worthi me he past
He grantyt him to put them all to ded:
Thai left nane quyk, syne brocht Wallace his hed;
Apon a sper throuch out the feild it bor.
The Lord Cambell syne hint it by the har;
Heich in Cragmore he maid it for to stand
Steild on a stayne for honour off Irland.
