Battle of Flers - Courcelette / Unknown soldier

[Guest alyson]

I have recently gained information from service records of my relative Albert William Richardson. He was attatched to 15th Battalion of Durham Light Infantry and died on 16th September 1916. Originally with the 8th Bat he was drafted to the 15th on the 1st September 1916 which leads me to believe he was present at the battle of Flers-Courcelette (war diaries of 15th Bat) Albert was killed in action in the field according to his service records but has no known grave. He is remembered on the thiepval memorial and Hednesford Staffs memorial in his home town.

I know that this would be speculation........but if he was one of the many soldiers who died and was buried unidentified, given his whereabouts at time of death, could anyone hazard a guess as to which cemetery he might have been buried if indeed he was buried at all?

Any information regarding any of the data I have mentioned would be gratefully recieved.

Regards

Alyson
