Tony Robinson and the Team visit the remains of Hopton Castle in Shropshire. Although it's picturesque, it was the site of a series of gruesome battles that took place at height of the English Civil War, when a Royalist force laid siege to a small garrison of Parliamentarians inside the castle. The Team use contemporary accounts and the evidence from their own trenches to separate fact from propaganda and piece together a blow-by-blow account of these violent days in 1644. The dig immediately produces evidence of battle. Over three days the archaeology begins to build up a compelling story of how the defenders fought off two attacks, killing hundreds of Royalists, before finally succumbing to the greater numbers of their enemy.
