Our map illustrates the battlefield sectors of the 1914-1918 Western Front. The line of battlefields ran through a wide variety of landscapes from its northern end in the dunes of the West Flanders Belgian coast to the frontier crossing at the village of Pfetterhouse on the Swiss-German (Alsace) border. The Franco-German border east of Belfort and St. Dié is shown on this map as it was in 1914 when war broke out.
