According to Major, the Clan Cameron and Clan Chattan both having deserted
Alexander of Islay, Earl of Ross attached themselves like honest men to the king, but on the
Palm Sunday following the ''Clan Chattan put to death every mother's son of the Clan Cameron''. Buchanan stated that many of the Mackintoshes and almost all of the Camerons were slain. The Clan Cameron account states that the
Clan Mackintosh who were leaders of the Chattan Confederation attacked the Camerons when they were worshiping in a church and that during the engagement most of the Mackintoshes and almost the whole tribe of Camerons were cut to pieces. ==References==
