Book excerpt: "Major General William "Bull" Nelson played a formative role in the Union's success in Kentucky and the Western theater in the CIvil War... David C. Clark presents a long-overdue examination of an irascible officer, his numerous accomplishments, and his grim fate ... During September of 1862, in a crime that was never prosecuted, fellow Union general Jefferson C. Davis shot and killed Nelson after an argument. Clark explores this remarkable exception in military law, arguing that while the fact of the murder was indisputable, prosecution of the murder went by the wayside because a public angered by the arrogant behavior of Federal officers generally approved of Davis having dispatched an abusive tyrant ... This comprehensive study -- the first biography of Nelson -- eliminates previous misconceptions about a well-known yet misunderstood Civil War general"--Dust jacket.
