The population was 945 at the 2010 census. Founded in the late 1800s, the town is named after prominent businessman and railway official William H. Henning. The infamous Battle of Fort Pillow, a Civil War victory for the Confederates, took place near Henning. Here, nearly 300 black troops serving in the Union Army were massacred after surrendering by Confederates under the command of General Nathan Bedford Forrest. The Confederate refusal to treat these troops as traditional prisoners of war infuriated the North, and led to the Union’s refusal to participate in prisoner exchanges. Union survivors’ accounts, later supported by a federal investigation, concluded that African-American troops were massacred by Forrest’s men after surrendering.
