For nearly a century and a half most historians of the Civil War have accepted the claim by Confederate Colonel John S. Mosby that George Armstrong Custer bears all of the guilt associated with the summary executions of six of Mosby's Rangers at Front Royal, Virginia on September 23, 1864.

This book challenges that view through a comprehensive look at the events of the day and a history of the persons involved, contending that Custer was not responsible for these executions, being neither present on the scene nor the initiating officer.
