Despite his reputation for rash decisions, brutal tactics, and intemperate behavior, Ulysses S. Grant was the only Union general who could win the war for Lincoln. Grant's aggressive strategies, swift movements and uncompromising battlefield attacks were praised in the North, feared in the South, and reviled by many of his own associates and staff.

General Grant is, perhaps, one of the most controversial, enigmatic, and misunderstood generals in our nation's history. In this new biography of Grant, acclaimed Civil War historian Edward G. Longacre examines Grant's early life, military training at West Point, and his later military career for insights into his great battlefield successes and his personal misfortune. Longacre, to a degree that no other historian has done before, investigates Grant's drinking as well as his devout religious affiliation with temperance movements, and the role these conflicting forces had on his military career and conduct.

Longacre's conclusions may surprise readers, but no one will doubt the research and scholarship behind them. As he has done in all his previous military biographies, Longacre challenges readers and scholars alike with a new perspective on the ever-fascinating life of General Grant.
