Basil became a commander of Redwall, and fought against Cluny. He showed up just in time for lunch. Basil consoled Matthias when Methusaleh the gatekeeper was murdered by Chickenhound. Basil then was instrumental in the downfall of Asmodeus because he told Matthias how to find him. Basil was captured by Cluny and the horde when Cluny conquered. Basil bravely insulted Cluny by saying he was an insolent barbarian, and Cluny stung Basil with a club. Basil joined in the fight when Matthias arrived, slaying many rats, and lived to the end of the battle.
