Basing House in Hampshire, owned by the Paulet family was once one of the largest private homes in Britain until besieged and destroyed in the English Civil War. Most of the ruins are a Protected Ancient Monument, but Time Team is permitted to dig on the edge of where the Basingstoke Canal once cut through the ruins, and they find evidence of the final assault in 1645. Meanwhile, in a field across the road, it appears that Charles Paulet built a hunting lodge around 1690, but the field is the site of centuries of building and tearing down, and the archaeology is so confusing three days are not enough to work everything out. The English Civil War Society come to re-enact the siege of Basing House, setting up camp in the Great Barn where the original besiegers camped. They show how musket and pistol balls were cast.
