“ Talking about an official story sometimes involves classifying the analysis of the events. In this case; however, it aims to contribute to thousands of women and men´s historical memories which we have shown in the ELN and where we have shown our lives as a faithful and vivid testimony of the fight of a country which after more than five centuries having been eradicated from its original idyosyncrasy goes on looking for its freedom to decide its own fate. In this book, readers will read a historical piece of writing of more than thirty years of fight in which its characters left and leave their popular mark, heart and life everyday so that the new generations are proud of their ancestors in the same way as we are of ours nowadays.” These words were pronounced by Nicolás Rodriguez Bautista; the commandant, when the first Colombian edition of this book was published.
