However, according to 19th century historian Alexander Mackintosh-Shaw the evidence is against this and that Malcolm Beg Mackintosh actually died in 1457 which was forty-five years after the Battle of Harlaw, quoting charters granted to Malcolm in 1443, 1447 and 1456 to back this up, and also the Macknintosh's own manuscript history.
In 1429, Alexander of Islay, Earl of Ross, in rebellion against the king, burnt Inveress but was not able to take the castle from Mackintosh.
[1] This was followed by the Battle of Palm Sunday between the Mackintoshes and Clan Chattan against their long standing rivals, the Clan Cameron and which is mentioned in several accounts such as Walter Bower (c. 1385–1449) in his work Scotichronicon, John Major (1467–1550) in his History of Greater Britain and George Buchanan (1506-1582) in his History of Scotland, Rerum Scoticarum Historia.
[2] Mackintosh's men who had formed part of the royal army that opposed Dòmhnall Ballach Mac Dhòmhnaill of Clan Donald, had been sent to Ardnamurchan and so were not in the subsequent Battle of Inverlochy in 1431.
[1] In 1454, occurred the Battle of Clachnaharry against the Clan Munro after the Munros, returning from a cattle raid, had passed Mackintosh's seat at Moyhall without paying to Mackintosh a share of the booty or road callop for passing though his dominions.
