The ending (Spoilers)

So what do you think happened at the end to Foster and Tarkington on the cliff? Tarkington says he'll do his best to see that Foster isn't shot by the Germans, he is wearing a German uniform, and they even joke that Rommel wouldn't shoot two stamp collectors. But the way that last scene is shot makes me think they were gunned down on the spot. The German soldiers accompanying the Panzers approach the duo in a long line, guns pointed at them.

Maybe it was just me, but that seemed pretty ominous to me. It even had Foster and Tarkington laughing, possibly at their own deaths? This could all be overanalyzing, but I'm curious either way what other people think.
