In 1567, a conflict took place between the Clan Campbell and Clan Arthur. Duncan MacArthur and his son of the Loch Awe MacArthur family, became the victims of their own success when jealousy of their power drove neighbours to drown them in Loch Awe during a skirmish with the Clan Campbell. In the archives of Inveraray Castle a charter dated 1567 confirms that a pardon was granted to the Campbells of Inverawe for what became known as the "drowning of Clan Arthur". It is believed that the MacArthurs trying to defend themselves were driven into the loch. Centuries later in the 1970s an ancient sword was unearthed on the shore of the loch.
