In about 1577/78 another feud arose with the Mackenzies due to a dispute between Thomas Fraser of Knockie, Tutor of Lord Lovat and Colin Cam Mackenzie of Kintail over the lands of Beauly Priory and the neighbouring estates to the north of it. Mackenzie assembled his followers and marched into the district with the intention of appropriating them to himself. Fraser of Knockie gathered his forces at Beauly and Munro of Foulis who was a friend of Fraser advanced with 300 of his followers to the banks of the River Conon. This formidable array alarmed Mackenzie, and he entered on peaceful negotiations.
