In this episode Al meets ‘the Auld Enemy', where bitter sibling rivalry is as strong today as it's ever been. Joined by Sanjeev Kohli, Al visits Craufurdland Castle to explore the truth behind famous battles from the Wars of Scottish Independence. The pair don mighty (pedal-powered) steeds to recreate the legendary axe attack from the battle of Bannockburn, claim independence for a town that's switched sides too many times to mention, and explore just how effective ‘cow camouflage' is when invading a castle.
