Robert Capa’s most famous photograph remains a mystery to this day. What we know is that both Capa and Taro were present at the scene of the event, and that the image was apparently captured on 5 September 1936. The soldier’s identity is not known, but thanks to the investigations of the Spanish researcher José María Susperregui, the place has been identified: Espejo, a village near Córdoba. Since there was no fighting at the time in Espejo, the soldiers staged a battle scene for the photographers. The image was published on 23 September in the French magazine Vu next to another, even more mysterious, photograph of a falling soldier. The copy on display here comes from the Life archive and, as evidenced by the reverse, it was used several times. The fact that other copies have different formats raises the question about which camera was used to take the photograph.
