MacGillechriosd's son Christopher Macrae became constable of Eilean Donan in turn, and held the castle during yet another clan feud, this time between the Mackenzies and the MacDonalds of Glengarry. Feuding broke out in 1580 and continued for almost 25 years. In around 1602 Eilean Donan was the base for a sea skirmish at the narrows of Kyle Rhea led by Christopher's son Duncan. During the action the MacDonalds were driven on to the Cailleach Rock at the eastern tip of Skye and Angus, son of MacDonald of Glengarry, was killed. Christopher was succeeded as constable by the Rev. Murdoch Murchison, minister of Kintail.
