"Abolitionist of the Most Dangerous Kind is an extraordinary biography of militant abolitionist James Montgomery, who helped slaves escape through the Underground Railroad, became a guerilla chieftain of the antislavery Jayhawkers vigilantes, and led regiments of both white and black troops for the Union during the Civil War. Meticulously researched, this is at once both a detailed historical study and an enthralling portrayal of one man's controversial life dedicated to the eradication of slavery at all costs."--Midwest Book Review

"Abolitionist of the Most Dangerous Kind is a capably written and commendably researched study that convincingly challenges the popular perception of a controversial figure and his approach to combating the slave system. As a fighting abolitionist who understood earlier than most white people that the "slavery question burned at the war's core," Montgomery--and the border war that produced him--proved a harbinger of the type of "destructive war" required to settle the slave question once and for all."-- Missouri Historical Review

"James Montgomery was a complex man, who lived a complicated life during a trying time in American history. Abolitionist of a Most Dangerous Kind tells Montgomery's life story, warts and all, in a way readers will appreciate. Richly illustrated with period images, photographs, and excellent maps, it is sure to be the definitive biography of Montgomery for years to come."-- Emerging Civil War

"Abolitionist of the Most Dangerous Kind illuminates the life of this controversial character, charting James Montgomery's evolution into a full-fledged abolitionist on the prairies of Kansas and leader of an all-Black regiment during the Civil War. Thanks to the authors' diligent research, Montgomery's story is now situated within the broader context of resistance to slavery."--Kristen Epps, author of Slavery on the Periphery: The Kansas-Missouri Border in the Antebellum and Civil War Eras

"In this carefully researched and crafted biography of James Montgomery, the authors tell the story of an often-overlooked Kansas Jayhawker: a curious blend of God-fearing pioneer farmer and preacher who became an anti-slavery zealot on the Kansas-Missouri border and a celebrated commander of Black troops during the Civil War. Montgomery's life was momentous and worthy of the attention it is now receiving."--Virgil W. Dean, editor of Kansas History: A Journal of the Central Plains (1990-2011)

"This well-researched book vividly re-creates the tumultuous life and times of James Montgomery, a genuine firebrand who helped precipitate and radicalize the American Civil War. We see the guerrilla chieftain in prewar clashes against pro-slavery terrorists along the Kansas-Missouri border transform into the Union colonel who recruited Black soldiers and then led them in combat and raids that laid waste to stately Southern plantations and brought freedom to the enslaved. Abolitionist of the Most Dangerous Kind peels away layers of myth and introduces us to a driven and courageous man."--Gregory J. W. Urwin, author of Victory in Defeat: The Wake Island Defenders in Captivity, 1941-1945
