"Aura" is a picture book of idealists, showing the daily life and death of members of the International Brigades. In 1936 the Spanish Army, with Nazi and Italian assistance, rose to overthrow the elected government of Spain. Only the Soviet Union was then a determined enemy of Fascism, and organized a call for volunteers to help defend the Republic. (England and France were "accommodating" the Nazis) Volunteers from 54 countries answered the call. Many were Jews or Communists (pg. 70), some were neither. Robert Merriman (Hemingway's Robert Jordan in For Whom the Bell Tolls), a Berkeley economist, was studying Socialism in Russia as an alternative to a perceived failure of Capitalism. They voluntarily risked their lives, and a quarter died, out of their belief that they were defending Democracy. This is a pictorial history of their story. But you will also read (pg. 200): "For the first time in the history of the people's struggles, there has been the spectacle, breath-taking in its grandeur, of the formation of International Brigades to help save a threatened country's freedom and independence...they gave us their youth, their maturity, their science or experience, their blood and their lives, their hopes and their aspirations, -- and they asked nothing at all...they did aspire to the honor of dying for us...in face of the shameful , 'accommodating' spirit.." These young men acted at a time which pre-dated Stalin's purges and paranoia, as he tried unsuccessfully to bring the West into a Popular Front against Fascism. There is no doubt that the book does not present the shadow side of the Civil War, the slaughter by the fascists in Badajoz answered by Republican slaughter of prominent fascists in Madrid, burning of convents, execution of capitalists, "Trotskyites" etc, all of which has no connection to our concepts of Democracy. Were these young men Stalin's tools? Perhaps, but the quotation above explains why Capitalists and Christians like myself can find nobility in the voluntary sacrifice of men with whose ideology (with 60 years of hindsight and capitalism's success) we have little in common.
