Father-and-son team Peter and Dan Snow embark on an epic journey to describe battles that transformed the 20th century. The Snows visit the scarred terrain of the Western Front in Northern France to tell the story of the 1918 Battle of Amiens. Peter uses state-of-art graphics to reveal how the British army used new tactics to break the back of the Germans, while Dan describes what it was like to fight in a new age of modern warfare, and as part of the biggest tank battle history had yet seen.
