Lately I've been really digging on the YouTube channel military history visualized and another guy named Bismarck.
I was curious if anyone had some suggestions on other similar guys.
Also, if you're unfamiliar with those I mentioned, I'd recommend checking them out if you're into that kind of stuff.
I assume you're aware of The Great War series
For videos analyzing specific battles in history, I think Baz Battles is pretty good.
For a simplistic summery of historic events there is Extra History.
For the most part I think the bazzillion documentaries that can be found randomly scattered across youtube are what I prefer. I'll search for an event as a start point, then fall into a youtube hole that can lead anywhere.
