Battle Of Guillemont
The Battle of Guillemont was a British assault on the German-held village of Guillemont during the 1916 Battle of the Somme.
Guillemont lay on the right flank of the British sector where it linked with French forces and by holding it, the Germans prevented the Allied armies from operating in unison.
In World War I, Guillemont was one of several important strategic areas controlled by Germans that effectively divided allied forces. It was exchanged several times during the war, before being finally taken and held by the British 20th (Light) Division| and the 47th Brigade of the 16th (Irish) Division.
