The Beleagured City: The Vicksburg Campaign, is another another good quick read.
Before his death, Foote was with the
Modern Library publishing company.
He wrote nothing new, but did select enough parts of his narrative to create a very good "Cliff Notes" version of his own famous narrative about specific campaigns.
He did the same with
Stars in Their Courses ... about the Gettysburg Campaign.
IMO that was a good business decision on Shelby's part.
All he had to do was edit what he had written decades before, ... repackage ... and sell to a new audience.
