...and many of the rest were killed, because they were resisting, and/or to cow others who might have tried to resist.
You're missing the point: telling victims they're victiming wrong (literally, as in, "You're doing that wrong", which is so unbelievably much of this thread) is bullshit. It's especially so if you have no relevant experience on which to make that judgement, and that goes double if your likelihood of having that experience is structurally negligible. Hand-waving about how someone should handle something that has never — and, for practical purposes, will never — happen to you is ludicrous on its face.
General form: Why don't victims behave the way I think they should, in circumstances I've never experienced?
