Hi there.
I think that movie with the Civil War soldiers coming back to life was called The Supernatuals, quite an enjoyable low-key flick, directed by Armand Mastroiani and starring Nichele Nichols and Maxwell Caulfield.
Another civil war era horror movie is Shadow of Chakira from 1976 (and which has other titles) starring the great Joe Don Baker and Sondra Locke, which the BBC showed a couple of times in the 80s.
A further movie set in the civil war is The Killing Box with Corbin Bernson from the early 90s.
Going off at a tangent there is an alien encounter movie from Empire Pictures called Zone Troopers which takes place in the Italian campaign of WW2.
Cheers.
Iain
