This book presents a left which, in the midst of civil war and revolution, chose to oppose both fascism and the popular front. The revolution in Spain was overturned by Stalinists and their allies. The Popular Front government of Doctor Negrin facilitated the destruction of collectives and permitted the work of Russian secret services, the murder and torture that demoralised workers and peasants. This book presents a spectrum of contemporary left viewpoints, introduced and annotated in detail.
