In the Alsace town of Mutzig in 1940 they dug a big trench in the mainstreet to stop the advancing germans. As they took the town they had to fill the ditch fast to advance their vehicles. So they took an captured Renault FT-17 tank and dumped it in the ditch and filled it over with dirt. It was later asfalted over. So now the big question is the renault still there? At your shovels...:-D
