The American Civil War [PDF ebook] 

Originally published in 1975, this assessment of the American Civil War is a broad treatment of the war as a major historical event, set in the context of a detailed picture of two governments, economies and societies at war. It discusses many controversial topics — the uncertainty and hesitation that surrounded the origins of the war, for example, its economic impact, the Radicals and their relationship with Lincoln and reconstruction as a wartime issue. It offers acute analysis of Lincoln’s political skills, and an evaluation of emancipation and Lincoln’s approach to it; the problems and performance of the opposition during the war; international reactions; an assessment of some of the leading generals like Mc Clellan and Lee and the impact of the war on both Southern and Northern society.
