Superb visuals, but hardly revolutionary.

First I'd like to say this is an awesome documentary. The script is very well done, informative, and fascinating to say the least. The footage is authentic, in colors, and probably the best I've seen in a WW2 documentary. It's hard to compress WW2 in only 6 episodes but this manages it, even if it is focused on Europe.

However It continues to spread disinformation and inaccuracies that arose from German propaganda and early (western) historical misconceptions on the Polish campaign.

1. Although far from the worst, Polish resistance is downplayed especially in comparison to the French one, even if the Germans actually had fairly high casualties on this front. For instance, the Polish airforce, even with obsolete planes managed to shoot down 285 German planes, losing about 330 themselves. However the Germans several times their numbers in aircraft.

2. The documentary claims that Polish horse cavalry charged German tanks (and were thus doomed to lose). There is no historical basis for this, and is a result of German propaganda to ridicule the Polish "Üntermench." Yes the Polish had horse cavalry, and a long proud tradition for it, but they never attempted to actually charge armored forces.

Instead most of the Polish cavalry fought dismounted, and had access to Anti-Tank guns and other infantry weapons. The few times they actually did charge the enemy they were mostly successful and actually managed to rout German infantry and weapon crews. Despite this success the commanders were very reluctant to use cavalry charge as a tactic, knowing full well how poor it is against entrenched infantry with machineguns.

3. And of course it presents the invasion of Poland as a textbook example of Blitzkrieg, while the actual strategies used where based on the old-fashioned encirclement tactics where the armor, artillery and airforce supports the infantry in surrounding the enemy and destroying them in detail.

Of course I'm no expert and there may be more examples of inaccuracies, but overall I think it was a very good series.
