This volume uses biographical sketches of twenty-one Union generals to tell the story of the Civil War and examine the implementation of Northern strategy. Among these generals are prominent figures like Ulysses S. Grant, George McClellan, and William T. Sherman, as well as Daniel Sickles, whose actions sparked intense controversy at Gettysburg, and the lesser known John McClernand, a congressman who lobbied for his own appointment. In Wilmer Jones's accounts, which focus on character, personality, leadership ability, military skill, and politics, each general comes starkly to life.
