First Bull Run/Manassas

Abstract

Abstract This chapter examines the First Battle of Bull Run, also known as the First Battle of Manassas, and argues that the Civil War’s first battle represented the last battle of antebellum military cultures of free and slave states. Before the Civil War, Americans refused to maintain a large U.S. Army. In the antebellum era, states organized local militia units based on their perception of internal and external threats; fear of slave revolt prompted slave states to maintain larger, more effective units, particularly cavalry units. Troopers who manned cavalry militia also staffed the slave patrols that brutally enforced the slave regime. In contrast, free states had no such fears, and their militias were moribund before the Civil War. When war came, slave states’ superior military capability led to Confederate victory at Bull Run/Manassas. Later, volunteer units from the free states achieved a level of competency that overcame this initial disadvantage.
