Les assassins de Durrivi by Sylvain Fourcassié investigates the circumstances surrounding the death of Buenaventura Durruti, one of the most prominent anarchist figures during the Spanish Civil War. Published in 1998 by Verticales, this 126-page work delves into the political intrigue, conflicting accounts, and historical debates about who was responsible for Durruti’s assassination in Madrid in November 1936. Drawing on archival sources and testimonies, Fourcassié examines whether his death resulted from enemy action, internal betrayal, or accidental friendly fire. The book situates Durruti’s legacy within the broader context of anarchist movements and the turbulent dynamics of Republican Spain, offering a focused historical inquiry into a pivotal moment of the conflict.
