• The high resolution film scans look great. They are the main attraction here so be sure to watch it in HD. The colorizing is good too, making the footage more powerful for today's audience, although I can imagine that future improvements will eventually make it look dated.

    The script repeats an old error about the Polish cavalry units in Ep. 1. A brief clip of men charging with sabers drawn is narrated "The Polish cavalry charges the German tanks, and is slaughtered." This is nonsense and insulting. World War I taught every cavalry officer that cavalry charges were a thing of the past. Polish cavalry c.1939 were not classic cavalry. The were highly mobile infantry units which used horses to move but then fought dismounted. They were highly effective in that role.
