"In a close study of the fifteen months from November 1956 to July 1958, when the urban underground leadership was dominant, Sweig examines the debate between the two groups over whether to wage guerrilla warfare in the countryside or armed insurrection in the cities, and is the first to document the extent of Castro's cooperation with the llano. She unveils the essential role of the urban underground, led by such figures as Frank Pais, Armando Hart, Haydee Santamaria, Enrique Oltuski, and Faustino Perez, in controlling critical decisions on tactics, strategy, allocation of resources, and relations with opposition forces, political parties, Cuban exiles, even the United States - contradicting the standard view of Castro as the primary decision maker during the revolution."--BOOK JACKET.
