On October 20, Capone arranged a peace conference with the Northsiders, held at the Hotel Sherman, at Clark and Randolph. "Big" Bill Thompson, the former Chicago mayor who was planning a political comeback, served as the impartial mediator.
The Northsiders demanded that O'Banion's assassins, Scalisi and Anselmi, be punished by Capone. But even they seemed to have been impressed with Capone's earnestness for peace. He argued:
I couldn't stand hearing my little kid ask why I didn't stay home [in Chicago]. I had been living in the Hawthorne Inn [in Cicero] for fourteen months....If it wasn't for him I'd have said, 'To hell with you fellows! We'll shoot it out.' But I couldn't say that, knowing it might mean they'd bring me home some night punctured with machine gun fire.The conference led to a general amnesty between the gangs, in which all murders performed in the past were considered closed with no further repercussions. Drucci and Moran would control the Northside areas of the city near the lake, and Capone would control the Southside below Madison, plus Cicero. There was not a single gangland murder for 70 days after the conference, the longest period without gang violence in years.
The Sherman House, which was originally built in 1837 by Francis Sherman (father to William Tecumseh Sherman, the famed Civil War general), had been rebuilt after the Great Fire as the poshest hotel in town, and was one of the first establishments in Chicago to offer jazz entertainment to white audiences. The hotel remained open until 1973, and was razed in 1980 to make way for the State of Illinois Center, later renamed the James R. Thompson Center, pictured here. Possibly Chicago's most unusual building, the Thompson Center is either an architectural masterpiece or a hideous spaceship/toilet, depending upon who you ask.
