Amiens

Available for over a year

In August 1918 after years of disappointment, bloodshed and stalemate, Allied troops launched a surprise overwhelming attack on the German Army - a short, four day battle in which the Allied forces advanced 12 miles, more than the total advance of the Somme and Passchendaele offensives combined. Veterans recall how they did it. Presented by Dan Snow Produced by Megan Jones for BBC Wales
