In this vivid firsthand memoir, Ami Frank Mulford, a bugler with the 7th U.S. Cavalry, recounts the harrowing experiences of one of the U.S. Army's most arduous frontier campaigns—the pursuit of the Nez Perce during 1876–77. Told with clarity, urgency, and surprising emotional depth, Fighting Indians in the 7th United States Cavalry captures the hardships of long marches, skirmishes in rugged terrain, and the complex moral and human dimensions of a conflict that pitted a determined Indigenous nation against the relentless machinery of westward expansion. Mulford's recollections include detailed accounts of encounters with Nez Perce warriors, daily life in a military encampment, and the personal costs of a war few soldiers fully understood. His tone is reflective rather than triumphant, acknowledging the bravery and suffering on both sides. Beyond battle scenes, the narrative sheds light on the role of the bugler—a key communicator in pre-radio warfare—and gives readers a unique perspective on how orders, morale, and coordination were maintained in the chaos of 19th-century combat. For readers interested in military history, the Indian Wars, and the human realities behind historical headlines, this memoir offers a rare window into the U.S. Cavalry's campaign against a people fighting to retain their homeland and dignity.
