The artist, librarian, historian and scholar Lucio Tarzariol from Castello Roganzuolo uncovers the incredible testimony of a Venetian parish priest and highlights new tangible evidence confirming the presence of the Corporal Adolf Hitler in Italy, in Soligo in 1917, during the First World War, after the Italian defeat at Caporetto. Hitler was granted a short time off his regiment (the 16th RIR List) during which he went first to Dresden and Berlin, then he started the Austro-Hungarian infantry assistance service, and arrived in Italy, at Soligo, where he began a sentimental relationship with a local young woman who later on, in 1919, gave birth to a son. A little-known story, "that sounds incredible". The author Lucio Tarzariol has collected the deposition of the elderly parish priest of Soligo and here he reports it enhanced with new investigations and new evidence of the reliability of the event occurred in that small town in the province of Treviso. The key witness is Don Giovanni Pasin, the late parish priest of Soligo, who was a member of the charity congregation of Farra di Soligo (1881-1970), a parish priest with a rather flawless reputation, a close friend of John XXIII and of Cardinal Piazza, Patriarch of Venice, as well as administrator of the Bon Bozzola Hospital Institute. The news seems well-grounded, Adolf Hitler was in Italy between the end of 1917 and the spring of 1918. On his quest the author pursued the proofs and here he presents them all: photographs, testimonies, recent attestations, new calligraphic tests and the circumstantial evidence attesting to the truth of: "Hitler did leave a heir in Italy".
