Regardless of the fierce rivalry between the two clans, Clan Campbell and Clan Lamont allied together in 1544, unsuccessfully, to defeat an English expedition sailing through the Firth of Clyde into Scotland. Henry VIII wished to kidnap the infant Mary, Queen of Scots and raise her to marry his heir. Although the Campbell/Lamont alliance failed to stop the English force, the fighting gave the Earl of Lennox enough time to escort Mary to Stirling Castle and save the House of Stuart. Mary was later to visit Castle Toward in the early 1560’s and a great hall was hastily added to the tower house for the occasion. It is likely that in the civil war between Mary and her brother the Earl of Moray that the Lamonts were sympathetic to Mary’s cause.
