Dan Snow's Battle of the Somme

The Battle of Ancre and the Advance of the Tanks is a unique record of a terrible conflict: the final battle of the Somme offensive. Filmed in the midst of battle on the front-line at great risk to the cameraman, this silent film caused a sensation on its release in 1917. Now, in this special documentary, Dan Snow tells the story of that battle, using the newly restored film to cast a fresh light on these dramatic events.
