The investigation undertaken by Juan Salinas and Carlos de Nápoli contains enough evidence to cast doubt on historical facts that until recently were considered irrefutable. In "Overseas Sur," historians draw on accounts, testimonies, and documents to question the official version of Adolf Hitler's fate and the sinking of the Brazilian cruiser Bahia shortly after the end of World War II. According to the authors, Operation Ultramar Sur was Hitler's final gambit, consisting of an audacious escape plan to Argentine Patagonia. This intention became even more feasible when, in 2009, it was officially confirmed that the skull found in one of the Führer's bunkers, considered for over sixty years conclusive proof of his suicide, did not belong to him. Salinas and Napóli present documents, photos, and testimonies that prove the arrival of a submarine convoy carrying Nazi officials off the Argentine coast. Although it seems unlikely that the Third Reich's high command landed on the beaches of Miramar or Mar del Sur, to this day no one can or wants to be certain who arrived in that region. Based on extensive documentation, historians reconstruct the story of the sinking of the cruiser Bahia (July 4, 1945), the largest Brazilian naval tragedy ever recorded, with 336 deaths. Officially, the episode was considered an accident, a fact that the authors question by presenting documents that point to the ship's torpedoing. The Brazilian vessel's executioner was reportedly one of the submarines carrying the Nazi high command to South America. The USS Omaha's navigation log is one of the key documents supporting the historians' theory. The American cruiser rescued the Bahia's only surviving officer, First Lieutenant Lúcio Torres Dias. In this document, labeled confidential, Commander W. L. Reseman reports that "at 10:22 a.m. (July 8), I was called directly by the South Atlantic Force Command. I was informed by the admiral that, without a doubt, the cruiser Bahia had been sunk in the vicinity of aircraft guard station No. 13 (...) and that it was necessary for the Omaha and all available Brazilian ships to head to the area." After the tragic episode, the submarines met different fates, some of which are undetermined. One of them surrendered upon reaching the coast of Mar del Plata. Hundreds of people witnessed two others heading for the extreme south of the Atlantic. After a month of voyage, one of them also surrendered. Despite all the evidence, the nautical incident was covered up by the Argentine Navy in complicity with the British and Americans. In Brazil, the sinking of the cruiser Bahia was officially considered an accident.
