Dan Carlin recently completed a podcast series on the Ostfront - and it's an absolute all-time classic of its form. In one, two, three, four parts he tells the story of the entire Eastern Front campaign: how Hitler thought he could avoid repeating Napoleon's mistakes, how the advance took its toll on the soldiers, how such a vast area turned into a massive killing field, how the German campaign turned sour, how the Soviet people fought back, and how the Soviets turned the tide and advanced on Berlin.
It is brutal, brutal stuff. But fascinating - and Carlin's delivery makes it a thousand times better than any book, movie or radio show. It's a four-part series, with each part running at least an hour (most are up around 90 minutes). And it's free... which means you'll end up donating to Carlin's site just to thank him.
One of the many things he touches on is the phenomenon of the Nachthexen. During the war (Operation Barbarossa, for all you pedants), there were thousands of Soviet women who got involved in the war effort. Some signed up as travelling prostitutes for the Soviet troops ("So what did you do during the war, Grandma?"), some as snipers, and some as stealth bombers.
These were the Nachthexen. The Germans called them the "Night Witches" because they would glide over the frontline and silently dive-bomb the Germans, sweeping in silently before screeching like banshees, dropping bombs and terrorising the frostbitten German troops.
It's a fascinating story. Read about it here or - better still - download the Hardcore History podcast series.
Or, wait for Quentin Tarantino to make the movie...
