"In Brothers One and All, Mark H. Dunkelman identifies the characterstics of Civil War esprit de corps and charts its development from recruitment and combat to the end of the war and beyond through the experiences of a single regiment, the 154th New York Volunteer Infantry. Dunkelman offers a unique psychological portrait of a front line company that fought with distinction at Chancellorsville, Gettysburg, Lookout Valley, Rocky Face Ridge, and other engagements. Drawing on three decades of research and more than a thousand wartime letters and two dozen diaries kept by members of the 154th, he traces the evolution of natural camaraderie among friends and neighbors into a more profound sense of pride, enthusiasm, and loyalty forged as much in the shared unpleasantness of day-to-day army life as in the terrifying ordeal of battle." "Brothers One and All reveals precisely how esprit de corps gave the men of the 154th reason to keep marching and fighting despite boredom, homesickness, illness, and the death of comrades. And while Dunkelman notes the limits of regimental loyalty in instances of cowardice, malingering, and desertion, he finds that most of the men shared an abiding concern for their regiment's reputation and honor. Even after war's end, a strong sense of esprit de corps survived among veterans, who for decades attended regimental reunions and contributed to war memorials."--BOOK JACKET.
