Of course it matters tali and it would be great to know who he was,if he survived the war and if he did how he fared afterwards, unfortunately tens of thousands of men literally vanished into the mud of the Western Front and many of the bodies that were recovered were never identified. If you're ever in Belgium and get chance go to Ypre and have a look at the Menin Gate a memorial inscribed with the names of nearly 55,000 allied soldiers whose bodies were never found at 20.00hrs everything stops while men from the local fire brigade play the last post, and have done evey night since the 1900's apart from the time in WW II when the town was occuppied, it really brings home the amount of losses suffered. Still as I said my own opinion is that after all this time it would be wrong to identify him, as like the Unknown Warrior in Westminster Abbey, he whoever he was, has become a represenative off all the Tommies who served, whether they died and were never found or returned to their families
