Some 100,000 soldiers fought in the April 1862 battle of Shiloh, and nearly 20,000 men were killed or wounded; more Americans died on that Tennessee battlefield than had died in all the nation’s previous wars combined. In the first book in his new series, Steven E.

Woodworth follows Lew Wallace’s controversial march to the battlefield and shows why Ulysses S. Grant never forgave him; Gary D.
