Winner of the 2019 Brigadier General James L. Collins Jr. Prize

In To Win and Lose a Medieval Battle: Nájera (April 3, 1367). A Pyrrhic Victory for the Black Prince, L.J. Andrew Villalon and Donald J. Kagay provide a full treatment of one of the major battles of the Hundred Years War, which, perhaps because it was fought in Spain, is lesser known to scholars and general readers. Drawing information from contemporary European chronicles and the massive documentary collections of Spanish and French archives, the authors have painstakingly investigated the Iberian and European background events to Nájera and have in minute detail laid out how the army of Enrique II of Castile (assisted by Bertand de Guesclin) and that of his half-brother, Pedro I of Castile (assisted by Edward, the Black Prince), clashed at Nájera on April 3, 1367.

Winner of the 2019 Brigadier General James L. Collins Jr. Prize, awarded by the U.S. Commission on Military History for the best book on military history published in 2017 or 2018. The awarding committee praised the volume as 'a genuinely original scholarly contribution... comprehensive, balanced, and insightful... this 600-page magnum opus will significantly enhance our understanding of military history during a seminal period of human development.'
