Engrossing, well written, hoofbeat‑sounding biography. The unbelievable facts about Mosby are all there in the letters, field reports, war documents, and primary sources from which Siepel quotes profusely and effectively. He controls his material well. The book follows an appropriately swift-moving narrative pace, yet it carries a vivid and convincing sense of place in its impressions of the Virginia towns, villages, and countryside of the Civil War and Reconstruction eras. The guerrilla and partisan warfare employed by Mosby as a means of demoralizing and confusing the enemy, Siepel shows as a very effective instrument of warfare. Siepel follows Mosby not only through the Civil War but also through the so-called Peace afterwards.
