In the lead-up to the big 65th anniversary of the end of the Great Patriotic War, a series of documentaries were made in Russia covering almost every major battle of the war. I saw some of the episodes on TV and liked how they did them (and I am a war documentary connoisseur), my only problem was that I didn't understand most of what they were saying.
So it was with great joy that I came across the same shows on Youtube, complete with English subtitles! Although the grammar in the translation is horrendous it still gets the message across.
This show, called "The Great War", is broken into several series which are more akin to episodes. Each episode is 50 minutes long so is broken into 10-minute segments on Youtube but they are all lined up together so when one ends just click on the next one in line.
Here's a link to the first part of the first episode, covering Operation Barbarossa (the German invasion of the Soviet Union). Enjoy!
