Half a century after the events that took place in Chile during the period 1965-1973, history-loving readers can now know a version closer to the real truth. Historians have dealt, almost exclusively, with the historical development following the military pronunciamiento of September 11, 1973. Chile 1973 is an essential document to understand what happened before that date. The essay gathers the most relevant testimonies of the protagonists that marked the life of the country during the last thirty years of the 20th century. It also has the wisdom of interspersing the speeches of President Salvador Allende, the writings left by Generals Carlos Prats and Augusto Pinochet, or Admirals Fernando Porta and José Toribio Merino, as well as those of some of Allende's political friends, such as Fernando Alegría, Osvaldo Puccio and Hernán de Canto. The author has undertaken an arduous task, 50 years later, tracking down information in the magazines and newspapers of the time, in order to place each personage in his or her place and circumstances, debunk myths and contribute to a more objective vision of the events that so marked the future of Chile and that continue to have such an influence today.
