Joaquín Durán was an Augustinian friar who arrived to the Philippines in 1891. He worked in the parishes of Baliuag, Barasoain, Jaén and Peñaranda, where he was caught by the revolutionaries in June 1898. He got permanently crippled in one leg while being a prisoner and returned to Spain in 1901. Father Durán expresses in the prologue his purpose: “Our main object in tracing these pages has been only to present to our readers the terrifying dramas dictated by the horrific muse of the Katipunan and written with blood in the hearts of the Spanish prisoners. [...] I do not want in any way to be branded as passionate or biased either by the institutions or by the personalities whose acts are applauded or censured in this book. I naively confess that everything narrated in these episodes is covered with incontrovertible truth”. A work of undoubted interest for the reconstruction of the events of the Philippine revolution and complements the previously mentioned work of Fr. Ulpiano Herrero.
