I haven't had a chance, though I have read the stories about the real guys.
But those were known artifacts they were after. I am talking about a family perhaps, that has lived in a little house in a little French town since medieval times, that has family heirlooms passed down for countless generations. Or a house in a town in Germany that had a Roman sword that's been passed down for centuries. Things that would be known to the people who lived there, but not to the outside world...so when the bombs fell and the tanks battled, those unknown, but priceless objects were lost to history forever without ever being known.
