early chiefs of the clan, were described as "The Great MacLamont of all Cowal" (). Wars of Scottish Independence During the Wars of Scottish Independence, Sir John Lamont, Laumon's grandson and the Chief of the clan, sided with the MacDougall's of Lorne against Robert the Bruce. The MacDougall bid for the throne was foiled, and the Lamonts suffered along with their allies. Once Robert the Bruce was firmly situated on the throne, he and his line took vengeance against the clans that had opposed him. In 1371, Robert II gave the Lamont hereditary seat at Dunoon to Bruce supporter Sir Colin Campbell, Black Knight of Loch Awe. By the end of the 14th century, almost all of Clan Lamont's original Cowal territory had been lost to the Campbells.

Crossing into Cowal on a hunting trip, they encountered and raped three Lamont women. In a rage, Lamont clansmen caught up with the three courtiers and brutally murdered them. The incident was passed along to the King, who punished Clan Lamont by rescinding nearly eight square miles of their lands in Strath Echaig and granting them to the Campbells. As a result of this increasing lordship of Lamont lands, Clan Campbell became even more bold in asserting their power over Argyll, and more specifically, Cowal. Whether by force or through sheer kindness, in 1442 the chief of Clan Lamont gave permission for the eldest son of Sir Duncan Campbell to be buried at the ancient Kirk of Kilmun on the Holy Loch, which was within the confines of Lamont territory. The Highlands were impassable because of snowfall, and those conditions led to the request. After this, Campbell petitioned the Pope to found a Collegiate Church on the site. The Pope conceded, and Sir Duncan Campbell endowed the site. He turned the Kirk into a burial place for Campbell chiefs, and it remains so even to the current day. In 1472, Clan Campbell received charter for the lands around Dunoon, and they proceeded to turn the castle into their main seat. 16th century Regardless of the fierce rivalry between the two clans, Clan Campbell and Clan Lamont allied together in 1544,
