 The Grants maintained their ownership of the castle until 1512, although the raids from the west continued.In 1513, following the disaster of Flodden, Sir Donald MacDonald of Lochalsh attempted to gain from the disarray in Scotland by claiming the Lordship of the Isles and occupying Urquhart Castle.Grant regained the castle before 1517, but not before the MacDonalds had driven off 300 cattle and 1,000 sheep, as well as looting the castle of provisions.
