Unfortunately, very little could be ascertained about Oswald Dunn as much of his service history has been lost, other than that he lived with his father, J. R. Dunn at St. Leonards, off Rutland Street.  Additionally, Oswald used to sing in the local Church choir along wit several other casualties (see George Coultas for a full list).  He was probably called up after conscription had been introduced in January 1916 as he was attached to the 20^th Battalion, Northumberland Fusiliers, otherwise known as the 1^st Tyneside Scottish Battalion.  This was a pals battalion raised in Newcastle in 1914, and had a distinctive set of service numbers for those specifically joining which Oswald does not possess so presumably he was sent to them as a reinforcement later on. 

          He died of wounds just after the Battle of Hill 70 in France had ended, and was buried in Hagricourt British Cemetery.
