Cry Havoc!: The Crooked Road to Civil War, 1861
The premise of this book lends to the possibilities of an exciting read. The back cover blurb probably does this book more justice than I can write here:
When Abraham Lincoln took the oath of office, secessionists had created an independent republic in the deep South, but there was no war. Then, eight weeks later, came the explosion at Fort Sumter. The public reactions to that clash and to Lincoln's response sealed the nation's fate. But what if Lincoln had shown restraint over Fort Sumter and had delayed his proclamation calling for troops? Or what if Jefferson Davis had allowed Lincoln to resupply the garrison there?....
This should be a crackin' good read!
