Lachlan, you sure do know your stuff!
Tom was originally buried at Abancourt Communal Cemetary German Extension, just outside of Cambrais, and behind the German lines. His grave was ironically later moved to Flesquieres. I say ironically, because he had participated in the first tank battle in history there, and had passed within less than a mile of where his grave is now located. I somehow imagine him taking a break and gazing off into the distance, not knowing that he was looking at his future grave.
