First of all, there are two versions of this documentary available on DVD: the shorter version is a one DVD abridged version titled Civil War Battles, concentrating only on the battles. The 2nd, longer version is also titled Civil War Battles but is a three DVD set sold in seperate volumes titled; A House Divided; The Terrible Swift Sword; and The Union Restored. This three DVD set is the superior version. Although a documentary about the civil war, it is a totally different beast to the far more artistic work of Ken Burns and is not to be compared to it. Instead it is an excellent companion piece that concentrates more on the military aspects, covering many more battles in far more detail, including many scenes of re-enactments, as well as informative insights by several reputable historians about key moments in battles, the performance of particular generals, and the strategic consequences of those conflicts on the further developments of the war.
For those who are interested more in the battles, this is an excellent overview of major battles fought in the conflict. But it can also work well as a companion to the Ken Burns documentary, covering in far more detail the nature of the fighting and the battles themselves. Highly recommend.
