Walter arrived in France on the 22nd August 1915. He served for almost a year on the Western Front when his unit became involved in the Battle of the Somme. The Battalion, part of the 75th Brigade of the 25th Division, were involved in the very heavy fighting around the village of Thiepval and Walter had survived the first day of the battle, when the British army suffered some 60,000 casualties. The conditions were ghastly and eyewitnesses recalled that that the bodies of the dead were still lying on the battlefield many days later. The fighting was both intense and chaotic, therefore, it is not known at what point he was killed. He has no known grave and his name is recorded on the Thiepval Memorial, Somme, France.
