About seven years ago I started working with the idea of the recovery of the memory of Spain's recent history. First I considered an archaeological project centering on the material sediment of the Civil War in the old battlefields, specifically the Ebro front. At the same time, the Spanish Association for the Recovery of Historical Memory (ARMH) had begun to locate, excavate and exhume the mass graves from the Spanish war and post-war. After a protracted struggle with two successive Catalan regional administrations of opposing ideological signs who thwarted my project in Catalonia, despite my having funding from two US foundations (Fulbright and American Center) and the support of two Catalan universities, I ended up doing it in Burgos in collaboration with the ARMH. This book documents an exercise in citizenship by a group of Spaniards determined to rescue a part of their history which had been sequestered.
