No, that is not Ken Burns Documentary.
You may be able to watch it on a PBS site
The Civil War is an epic nine-episode series by the award-winning documentary filmmaker Ken Burns.

You may also be able to find it at a local library? You can also purchase it, but I don't know how much it costs. It was a nine-episode documentary that played on PBS television in 1990. It truly is inspiring, and I believe it sparked a resurgence in interest in the Civil War during the 1990's. I agree with everyone who said it would be good to watch. It is worth the time it takes to watch it. I think each episode is two hours. I picked it up used on VHS years ago and still watch probably at least once a year. Sometimes I just watch segments I am interested in, maybe because I have a trip to that area planned.
I also agree with everyone who suggested reading James McPherson's "Battle Cry of Freedom" book. There are so many other good books, but that is probably the best starter. Others are:
Shelby Foote's three book history titled, "The Civil War: A Narrative Volumes 1-3" It is three books long but excellent.
The book, "Killer Angels" by Michael Shaara is a fictional novel based closely on the history of the battle of Gettysburg, PA. It is only about one battle, but it is a very good book, and the movie "Gettysburg" was based on it. I suggest it only because it does introduce you to some of the important soldiers of the war.
I have to say though, that the "Battle Cry of Freedom" book would be the best starter book.
