Don Emilio Barzini and the Barzinis under caporegime Pietro Testa and caporegime Dante Marcelini began to expand into the Corleone territory, most of it run by Johnny Trapani and Luca Brasi. The Barzinis began the mob war by bombing Trapani's Bakery in Little Italy, which made tons of money for the Corleone crime family. Trapani was gunned down by the Barzinis after killing three of thee enforcers, which proved to be a tremendous blow to the Corleone income through rackets. Luca Brasi retaliated by killing Marcelini at his Midtown apartment, running him over with a car. The Barzinis made a new offensive, taking over northern Little Italy, forcing the Corleones to bribe an FBI agent to put the pressure on the Barzinis and thus end the war.
