The Advance in Picardy began with the Battle of Amiens on 8 August 1918. This was the start of the ‘Hundred Days Offensive’ forcing the Germans out of France and beyond the Hindenburg Line; it was a rapid series of victories culminating in the Armistice of 11 November 1918.

The British Fourth Army’s attack east of Amiens was later described By General Ludendorf as ‘the black day of the German Army’. The Advance in Picardy would include the Battle of Amiens 8 – 11 August 1918 and the Second Battles of the Somme, 23 August – 3 September 1918.
