There’s a war movie I remember from my childhood, an I have no idea what it was called. Every now and then I think about it, and I’d like to track it down again. I only remember two scenes (and I do hope they’re from the same movie).
In one, the refugees are hiding in an underground hidey-hole, and German soldiers are walking along in a line, pushing probes into the ground looking for any such voids. When the probe penetrates the roof of the hole, one of the refugees pushes up on the probe with his hand to offer resistance so the soldier doesn’t detect the hole, but the probe also penetrates his hand.
In another scene, the group are gathering smuggled weapons at a house in town. I remember one of them opening 1-2 suitcases with a bunch of straw inside, along with some grenades and an MP-40 submachinegun. IIRC, the Germans attack and grenades are thrown.
I saw this at some time in the 70’s or early 80’s. Ringing any bells?
