In 1645, during the campaigns of Montrose, a battle was fought at Callander between the Campbells of Argyll and the Atholl men. The Campbells were harassing the McGregors and the McNabs for their allegiance to Montrose. While besieging Castle Ample, the news came of the advance of 700 Atholl men under Inchbrakie. A retreat was made southwards, but, as the Campbells were crossing a ford to the east of the village of Callander, they were overtaken and compelled to give battle. Inchbrakie, advancing part of his force to attack the defenders, quietly marched another detachment towards a ford higher up near the present bridge. A crossing was soon effected, and the Campbells, being unexpectedly attacked on the rear, broke and fled, leaving eighty of their men dead on the field.
