My paternal Grandfather fought with the 8th KOYLIs (King's Own Yorkshire Light Infantry) on the First Day of the Somme, where he was seriously wounded. When he died we found these documents in his papers. I think they speak for themselves.
He survived the war and ended up as a Sergeant in the Department of the Military Secretary. He lived to the age of 94. He was instrumental in organising the 8th KOYLI reunion dinners every year until at least the mid 60's. If you want anything done, give it to an NCO.
