The Guerrilla Base of the King

S1 E1: In the first episode of Time Team, Tony and the team travel to Athelney in Somerset to investigate a series of hills (once islands in a bog) that became Alfred The Great's last defensive positions after a series of losses to invading Viking forces. It is also the place Alfred began the great rally that saw him re-conquer most Wessex and laid the foundations for the future England.
