The Battle of Inverlochy occurred on 2 February 1645, during the Wars of the Three Kingdoms, when a Royalist force of Highlanders and Confederate Irish troops under the overall command of James Graham, 1st Marquess of Montrose, routed and largely destroyed the pursuing forces of Archibald Campbell, 1st Marquess of Argyll, who had been encamped under the walls of Inverlochy Castle. After being researched, the area was designated as a battlefield by Historic Scotland in 2011.
