'Aldershot' appeared as the theatre of war for many deaths recorded in 'Soldiers Died in the Great War' as transcribed by one online organisation. After many complaints this has been corrected, I believe, to the correct 'France & Flanders'.
His place of burial was Etaples - this is from the Commonwealth War Graves Commission's Debt of Honour Register:

It should be possible to get a copy of the death certificate, but I do not know where the details are to be found. Someone will be along soon, I expect, who can tell you.
You can probably get a photo of the headstone from <
