What happened 1946AD in Cuba

In October 1946, Luciano secretly moved to Havana, Cuba. Luciano first took a freighter from Naples to Caracas, Venezuela, then flew to Rio de Janeiro, Brazil. He then flew to Mexico City and doubled back to Caracas, where he took a private plane to Camaguey, Cuba, finally arriving on October 29. Luciano was then driven to Havana, where he moved into an estate in the Miramar section of the city. His objective was to be closer to the US so that he could resume control over American Mafia operations and eventually return home.

In 1946, Lansky called a meeting of the heads of the major crime families in Havana that December, dubbed the Havana Conference. The ostensible reason was to see singer Frank Sinatra perform. However, the real reason was to discuss mob business with Luciano in attendance. The three topics under discussion were: the heroin trade, Cuban gambling, and what to do about Siegel and his floundering Flamingo Hotel project in Las Vegas.
