The Somme

Dermot O'Leary, Arthur Williams and Lucy Betteridge-Dyson examine the final 48 hours of the Battle of the Somme, which raged for over four months. Dermot spends time in reconstructed trenches and meets the descendants of a Glasgow soldier who was one of just 15 men in his battalion to survive, and Lucy meets a bomb disposal team who are still uncovering shells from the conflict to this day.
