Excellent, James, excellent! You ambush and arrest almost 50 of the most powerful Highland chiefs. Unfortunately Alexander, Lord of the Isles evades capture and returns to the west. Good riddance! You'll deal with him later.
Once again, your deceit has caused unrest among the political community. This is a controversial move, which has earned you a worse reputation among the Gaelic aristocracy in the north and west.
Alexander, Lord of the Isles is on the war path. In 1431, he defeats your army at Inverlochy. You are forced to submit to his command of the west. The Lords of the Isles are adamant to retain control of their lands and titles. Never mind, you still have a substantial kingdom.
