First Manassas: The Campaign

The first day's march covered only five miles, as many straggled to pick blackberries or fill canteens.

McDowell's lumbering columns were headed for the vital railroad junction at Manassas. Here the Orange and Alexandria Railroad met the Manassas Gap Railroad, which led west to the Shenandoah Valley. If McDowell could seize this junction, he would stand astride the best overland approach to the Confederate capital.

On July 18,  McDowell's army reached Centreville. Five miles ahead a small meandering stream named Bull Run crossed the route of the Union advance, and there guarding the fords from Union Mills to the Stone Bridge waited 22,000 Southern troops under the command of Gen. Pierre G.T. Beauregard. McDowell first attempted to move toward the Confederate right flank, but his troops were checked at Blackburn's Ford near the center of Beauregard's defensive line. He then spent the next two days scouting the Southern left flank. In the meantime, Beauregard asked the Confederate government at Richmond for help. Gen. Joseph E. Johnston, stationed in the Shenandoah Valley with 10,000 troops, was ordered to support Beauregard if possible. Johnston gave an opposing Union force the slip and, employing the Manassas Gap Railroad, started his brigades toward Manassas Junction. Most of Johnston's troops arrived at the junction on July 20 and 21, some marching from the trains directly into battle.
