In this episode we continue the story of the 6th Battalion of the Northamptonshire Regiment. We find them in flooded trenches at Fricourt during Christmas 1915, and discover what happened when the Germans carried out a raid on their positions and captured 20 of them. Who were these captured men? What happened to them and why were their trenches undefended? We also follow their preparations for the “Big Push” as they move to a new sector of the battlefield at Carnoy.
