Italian-American dockers who lived and operated in the area were investigated, Newark said, but officials struggled to make progress. So the U.S. government turned to Luciano because it knew his influence and contacts around the docks. The deal became known as Operation Underworld, with Luciano ordering its officers to look for suspicious activity. In return, Luciano made a deal to convert his sentence. This month marks the 75th anniversary of the Allied invasion of Sicily, known as Operation Husky. Considered a turning point in World War II, this might not have been possible without the help of an unlikely source – the mafia. The Navy speculated that these fishermen were either former rumrunners who were forced to go bankrupt at the end of Prohibition, or a massive conspiracy of enemy agents who were in New York Harbor. The task of uncovering the conspiracy fell to Captain Roscoe MacFall, a 40-year-old Marine veteran chief intelligence officer of the Third Naval District, an area that included New York, New Jersey and Connecticut. Waller points to a deal the U.S.
Navy made with the mafia during World War II to protect U.S. shipyards. And despite the absurdity of just about everything that happens in the film, this historical treatment is quite correct. At the beginning of World War II, the United States Office of Naval Intelligence that Italian and German agents invaded the United States via New York and that these facilities were vulnerable to sabotage. Above all, the loss of the SS Normandy in February 1942 aroused fears and suspicions in the Navy about possible sabotage in eastern ports. A Navy intelligence unit, B3, has tasked more than a hundred agents with investigating possible supporters of Benito Mussolini among the predominantly Italian-American fishermen and docker population on the waterfront. Their efforts were unsuccessful, as dockers and fishermen on the waterfront controlled by the Italian mafia were narrow and distant from foreigners.  The Navy contacted Meyer Lansky, a well-known employee of Salvatore C. Luciano and one of the main non-Italian employees of the Mafia, about an agreement with Mafia boss Luciano.
Luciano, also known as Lucky Luciano, was one of the highest-ranking mafias in Italy and the United States, serving a prison sentence of 30 to 50 years for forced prostitution in Clinton prison.  To facilitate negotiations, New York State moved Luciano from Clinton Prison to Great Meadow Correctional Facility, which is much closer to New York City.   ”He asked his lackeys to provide assistance for the invasion of Sicily, but it was essentially limited to postcards from the ports,” Raab added. .
