Brown did not plan to execute a quick raid and immediately escape to the mountains. Rather, he intended to arm rebellious slaves with the aim of striking terror in the slaveholders in Virginia. Believing that on the first night of action, 200 to 500 slaves would join his line, Brown ridiculed the militia and the regular army that might oppose him. He planned to send agents to nearby plantations, rallying the slaves, and to hold Harpers Ferry for a short time, with the expectation that as many volunteers, white and black, would join him as would form against him. He would then move rapidly southward, sending out armed bands along the way that would free more slaves, obtain food, horses, and hostages, and destroy slaveholders' morale. Brown intended to follow the Appalachian Mountains south into Tennessee and even Alabama, the heart of the South, making forays into the plains on either side.Allan Nevins, The Emergence of Lincoln: Prelude to Civil War, 1859–1861 (1950), vol. 4, pp. 72–73
