Here´s one I´m thoroughly enjoying atm.
APOCALYPSE - The Second World War - Episode 1 - The Aggressionr
https://www.youtube.com/watch?v=4RSCrvr6kBY

Tells the story, in 6 parts, from 1933 on. I watch alot of these and I´ve only seen mebbe 5% of the footage before.
I´m halfway through the second episode and I find it fascinating. It tells it like it was. No fancy music or rhetoric.

Warning: Right from the off it´s quite gruesome in places.
