I watched the somewhat disappointing first episode.
When Hitler postponed the original date for the invasion of Poland, one unit did not get the order in time. That unit invaded Poland on the originally planned date to take a vital RR tunnel and were defeated. The Poles had captured German soldiers with their written orders. So the idea that the Nazis invaded Poland with a surprise attack on 1 September may be what we tell school children, but that is simply untrue.
Poland was not able to adequately defend its borders because Hitler had absorbed the non-German remaining part of the Czech state a few months earlier. This allowed the southern Nazi forces access to hundreds of miles of undefended Polish border. Also, Guderian was not the only German whose ancestral Prussian home was inside the new state of Poland. The Treaty of Versailles ended the first world war by planting the seeds of the second.
The Poles had horse cavalry. The Germans had armored units. At some point, for whatever reason, the two met. The Russians used horse cavalry throughout the war. The Germans used horse cavalry too. In the film "12 Strong" about the actual Green Beret A-team that infiltrated Afghanistan after 9/11, a US Captain led a cavalry charge that encountered Taliban T-72s. Acts of desperation in war are not an embarrassment.
After 79 years, I would hope that any discussion of WW2 would involve the actual truth.
