That may be true...I wouldn’t know, I wasn’t there. I base that on the accounts told by many Jews (both native Polish and otherwise escaped Jews) who were nearly as concerned by encountering the general populace as they were of encountering Germans themselves for fear of capture.
I readily admit that it is likely they had reason to feel that way even if the percentage of Poles who would turn them in was relatively small.
And the ones who could have turned them in would alsohave been in fear of their and their families’ lives if the germans found out they had NOT stopped and handed over a jew (it would have been collaboration by the pole).
