I’ve probably read Barbara Tuchman’s book of the same name about half a dozen times, maybe more. It’s a massive read, I think; not for the faint-hearted and certainly a difficult one for the non-military-history reader.
TGOA is magnificent as a military textbook alone, but what Tuchman brings to the party is an exhaustive set of the biographies of the principal characters so that we can understand not just what they did, but in many cases why they did it.
And I know that Tuchman was a tired old New York Lefty, but not in this work.
Anyway, I happened on this EwwwChoob video which follows the book faithfully, albeit cutting a few parts out (because otherwise it would run for not 100 minutes, but for three days — about as long as it takes to read Tuchman’s volume).
And it has lots and lots of original footage, none of that tiresome reenactment nonsense. Enjoy.
Afterthought: Tuchman’s prequel to The Guns Of August, A Proud Tower, will change your ideas of history completely, and for the better. It did mine, at any event.
Also: link fixed.
