Harlots and Hooligans: The Sordid Underworld of a City at War” is probably not appropriate for children, says the Richmond National Battlefield Park , sponsor of the Sept. 21, ranger-led tour that will feature past locations of prostitution, drunken debauchery, daylight shoot-outs and murder.

Richmond was transformed by the war when an influx of soldiers and others led to a near tripling of the population, including those who are most willing to separate a man from his paycheck.

The two-mile, two-hour tour of the sites of Civil War Richmond’s neighborhoods of ill repute will take place three times: 10 a.m., 12:30 p.m. and 3 p.m. The tours are free.
