The 1st Battalion of the Hertfordshire Regiment left for war on 5th November 1914, sailing from Southampton on the SS City of Chester, arriving at Le Havre in the early hours of the morning on 6th November 1914. Their first spell in the trenches came in the Observatory Ridge Sector, near Zillebeke in the Ypres Salient. They remained on the Western Front for the entire war and took part in every major engagement throughout the conflict including the battles of Ypres, Loos, The Somme, Passchendaele and the German Spring Offensive of March 1918. The following map has been compiled using contemporary records; diaries, newspapers, postcards, military records and photographs to plot the exact location of the Hertfordshire Regiment, every day for the entire war.
