What Made the Civil War Unavoidable?

[LincolnMan]

It's been years since I read it, but at the time I really enjoyed reading Bruce Catton's "The Coming Furry"

A thrilling, page-turning piece of writing that describes the forces conspiring to tear apart the United States—with the disintegrating political processes and rising tempers finally erupting at Bull Run. -Amazon

Good used copies are not hard to find

One of the earliest books I read on the war as a young man. His writing is superb.
