Inspired by, though hardly based on, a Civil War event. After Atlanta had fallen to the Union, Sherman set up a supply dump at Allatoona. A Confederate force under General French attacked this base on October 5, 1864, and called upon Union General Corse to surrender. Soon after, General Sherman send a simple message to Corse: "Hold the fort; I am coming." Corse held out, and Sherman's troops arrived in time to drive off French. - RBW
