Eh? Were you hiding ?
Just didn't happen to draw my attention. My historical education is rather haphazard, and I wasn't particularly interested in the September Campaign.
For example, the 'cavalry against tanks' - I knew a different story than the currently prevailing. There was a German documentary showing clearly ulans charging at tanks. The explanation was, the surrounded cavalry unit chose a surprising charge as a means of breaking through. Tanks formation was the best choice in the situation, and the whole thing showed the clearness of mind of a Polish commander rather, than obvious stupidity. Losses were insignificant, 2 or 3 people. This might've been some other event, though, not Krojanty, I don't remember.
Question remains, how come there was a German cameraman at the ready during a surprising charge.
