In The Three-Cornered War Megan Kate Nelson reveals the fascinating history of the Civil War in the American West. Exploring the connections among the Civil War, the Indian wars, and western expansion, Nelson reframes the era as one of national conflict—involving not just the North and South, but also the West.

Against the backdrop of a larger series of battles, Nelson introduces nine individuals: John R. Baylor, a Texas legislator who established the Confederate Territory of Arizona; Louisa Hawkins Canby, a Union wife who nursed Confederate soldiers back to health in Santa Fe; James Carleton, a soldier who engineered campaigns against Navajos and Apaches; Kit Carson, a famous frontiersman who led a regiment of volunteers against Texans, Navajos, Kiowas, and Comanches; Juanita, a Navajo weaver who resisted Union campaigns against her people; Bill Davidson, a soldier who fought in the Confederacy’s major battles in New Mexico; Alonzo Ickis, an Iowa-born gold miner who fought on the side of the Union; John Clark, a friend of Abraham Lincoln’s who embraced the Republican vision for the West as New Mexico’s surveyor-general; and Mangas Coloradas, a revered Chiricahua Apache chief who worked to expand Apache territory in Arizona.

As we learn how these nine charismatic individuals fought for self-determination and control of the region, we also see the importance of individual actions in the midst of a larger military conflict. The Three-Cornered War is a captivating story—based on letters and diaries, military records and oral histories, and photographs and maps from the time—that sheds light on an overlooked chapter of American history.

One of Denver Post‘s Three Regional Books to Keep You Occupied While Homebound

“Based on extensive archival research, Nelson’s work expands our understanding of how the Civil War affected Indigenous peoples and helped to shape the nation. Readers interested in the Civil War and Western history will enjoy this nuanced portrait of the era.”—Library Journal, starred review

“Nelson effectively blends military history with a fresh look at a region typically obscured in accounts of the Civil War. American history buffs will relish this entertaining and eye-opening portrait.” Publishers Weekly

“In a narrative both engaging and unsparing, Nelson … balances the stories of individuals … with deft discussion of the big picture issues. … The result is a gripping history that integrates the Southwest into broader histories of American expansion.” —Booklist

“This volume fills a critical gap in the study of the American Civil War, narrating that it truly was a continental war with potential repercussions far beyond the Washington-Richmond corridor or the Mississippi River valley.”New York Journal of Books

“In The Three-Cornered War, Nelson combines meticulous research in military records, letters and diaries, oral histories, and photographs with novel-like prose to tell the story of the American Civil War through the experiences of nine individuals. As Nelson shows how each of these individuals shaped and were shaped by the Civil War in the continental southwest, the result is a history of the American Civil War truly continental in its scope yet deeply individual in its impact.”New Books Network Podcast

“Symphonic in scale, The Three-Cornered War blends masterfully the intimate and the epic, weaving the biographies of nine individuals into a story of peoples—Apaches, Texans, New Mexicans, Confederates, Navajos, Federals—whose tragedies and triumphs resonate in the West we know today.”
—James F. Brooks, author of Captives and Cousins and Mesa of Sorrows

“In the 1860s New Mexico and the greater West experienced many civil wars.  With lucid storytelling, using nine remarkable characters, Nelson reveals a chaotic, desperate struggle of Union against Confederate, Native peoples against other Native peoples, and Natives on both sides.  This is the Civil War most Americans do not know and Nelson convinces us once again that the great conflict was about slavery and the winning the West with its land and resources.  Rarely is a Civil War book so readable and so new to our understanding.”
—David W. Blight, author of the Pulitzer-prize winning Frederick Douglass: Prophet of Freedom

“Far from the Civil War’s famous battlefields, a handful of individuals decided the fate of a vast landscape. In The Three-Cornered War, Megan Kate Nelson vividly portrays a complex struggle between peoples and armies—Navajo, Apache, Confederate, and Federal—over the mountains and deserts of the Southwest. Fast-paced and suspenseful, Nelson’s account shifts perspective from the Navajo leader Juanita to the civilian Louisa Canby, from the Chiricahua titan Mangas Coloradas to the Texan Bill Davidson, among many others, in a web of conflicting agendas and shared suffering. This history of invasions, battles, and forced migration shapes the United States to this day—and has never been told so well.”
—T.J. Stiles, author of the Pulitzer Prize-winning Custer’s Trials: A Life on the Frontier of a New America

“A gripping tale of the Civil War in the West. Exploring the interaction of a fascinating cast of characters during a time of immense change, Nelson reveals an all too human struggle for territorial control. Shifting perspective between nine key characters — men, women, soldiers, and Native Americans — The Three-Cornered War brings this battle between peoples, armies, agendas, and the environment to living breathing life.”
—Joanne B. Freeman, author of The Field of Blood and editor of Alexander Hamilton: Writings

“Of the several “western theaters” in the Civil War that stretched 1800 miles from Knoxville to Tucson, the events and significance of the once farthest west is least known or understood. Union forces in New Mexico and Arizona repulsed a Confederate attempt to conquer this region and subdued the Navajos and Apaches in a successful effort to “reconstruct” the region into the United States. Megan Kate Nelson’s beautifully written account tells this important story.”
—James M. McPherson, author of Battle Cry of Freedom: The Civil War Era

The Three-Cornered War sheds a bright light on the forgotten intersection of America’s westward expansion and its cataclysmic Civil War. Full of irony, sharp character sketches and fast-paced battle scenes, Megan Kate Nelson’s book should be read by anyone who wants to understand the roots of modern America — or just wants a gripping story, powerfully told.”—Clay Risen, author of The Crowded Hour: Theodore Roosevelt, the Rough Riders, and the Dawn of the American Century
