THE SECOND BATTLE OF THE SOMME.

At different periods during the War, important events took place in the Plains of Picardy, in the region which extends between Amiens and St. Quentin, Bapaume and Noyon, between the valleys of the rivers Ancre, Avre and Oise.

The Franco-British Offensive of July-September 1916, and the German Retreat of March 1917, are described in the Michelin Guide "The First Battle of the Somme, 1916-1917", which includes carefully prepared itineraries, enabling the reader to cover the whole battlefield of that period.

The present guide describes the operations which took place in Picardy in March-April 1918 (The German Offensive), and in August 1918 (The Franco-British Offensive); in a Word, the ebb and flow of the German Armies in 1918, from St. Quentin to Montdidier.
