In July 1861, Union forces marched into Virginia expecting a quick victory that would end the Southern rebellion in weeks. What they got was a chaotic rout that sent both soldiers and Washington picnickers fleeing back toward the capital. This episode covers the strategic context, the key commanders, and why First Manassas forced Lincoln to reckon with the reality of a long, devastating war.

Key Takeaways

• Lincoln initially called up only 75,000 troops for just 90 days, reflecting the widespread northern belief that the rebellion would collapse quickly.

• Robert E. Lee turned down command of the Union Army on April 18th, 1861, the day after Virginia voted to secede, telling Winfield Scott he could never draw his sword against his native state.

• Rail transport played a decisive military role at First Manassas, one of the earliest examples in history of railroads being used to move troops to a battlefield in time to affect the outcome.

• Hundreds of Washington civilians, including politicians and journalists with picnic baskets, traveled to the hills near Manassas expecting to watch a Union victory unfold.

• General Thomas J. Jackson earned his famous nickname 'Stonewall' for the firm stand his brigade made during the Confederate defense.

FAQ - Frequently Asked Questions

Q1: Why was First Manassas such a shock to the North?

Northern public opinion had assumed the rebellion would collapse quickly. Lincoln's initial call was for just 75,000 troops serving only 90 days. Newspaper editors, politicians, and ordinary citizens believed one decisive engagement would end the Confederacy's resistance. The Union rout at Manassas, combined with chaotic images of soldiers and civilians fleeing together toward Washington, made clear that the assumptions were wrong and the war would be long.

Q2: How did railroads affect the outcome at First Manassas?

Confederate General Joseph Johnston used the Manassas Gap Railroad to move his forces from the Shenandoah Valley to the battlefield in time to reinforce Beauregard before the Union could defeat him in detail. This was one of the earliest examples in military history of railroads being used as a tactical tool to shift troops during a campaign, and it directly changed the outcome of the battle.

Q3: How did Thomas Jackson get the nickname 'Stonewall'?

During the fighting at First Manassas, General Bernard Bee rallied his faltering troops by pointing toward Jackson's brigade, which was holding its ground amid the Union assault. 'There stands Jackson like a stone wall,' Bee reportedly said. The nickname stuck. Jackson became one of the most celebrated Confederate commanders of the war.

Q4: Why did Robert E. Lee decline command of the Union Army?

Lee was a Virginian and felt his primary loyalty was to his home state. Though he opposed secession personally and had spent his career in the U.S. Army, he told Winfield Scott that he could not draw his sword against Virginia. He resigned his commission the day after Virginia voted to secede and accepted command of Virginia's military forces instead.

Q5: What happened after the Union defeat at First Manassas?

Lincoln called for 500,000 additional volunteers to serve three-year enlistments, a dramatic expansion from the original 90-day call-up. Congress began taking a harder look at Union military leadership. The loss at Manassas ended any expectation of a quick war and set the stage for the far more brutal conflict that would unfold over the next four years.

"On to Richmond", High Expectations

When the Civil War broke out, northern expectations were high. Not only would the Southern Rebellion be suppressed, the conflict would be a short one. President Lincoln enlisted just 75,000 troops and for only 90 days. The slogan "On to Richmond" became popular in the press, capturing the Confederate capital, Union supporters thought, would end the rebellion swiftly. Then came the first battle of Manassas in Virginia.

All expectations changed. The Civil War would last for nearly four years and proved the deadliest of all wars in American history. On May 20th, 1861, the Confederate capital was officially moved from Montgomery, Alabama to Richmond, Virginia. Virginia was the largest and most industrialized Southern state, a center for iron and munitions production, lumber, shipbuilding, and railroads. Its location was closer to the major eastern battlefront. Virginia's legacy in American republican history was unmatched. Founding fathers including Washington, Jefferson, Madison, Monroe, Mason, Patrick Henry, and the Lees were all Virginians. Then came the resounding Confederate victory in the Battle of Fort Sumter on April 12th, 1861. The deeper causes of the war reach back to the questions we trace in our episode on America's paradox of slavery and freedom.

Robert E. Lee Chooses Virginia

Between April 12th and April 14th, crowds poured into the streets of Richmond calling for independence. On April 15th, Lincoln called up 75,000 troops to suppress the Southern Rebellion. On April 17th, the Virginia State Assembly voted to secede from the Union. Of the 139 delegates who voted, 87 voted for secession.

Of those 87, 53 came from counties where more than 25% of the population were black slaves. Of the 52 delegates who voted against secession, 39 came from counties where less than 25% of the population was enslaved. On April 18th, one day after Virginia voted to secede, and at the recommendation of General-in-Chief of the United States Army Winfield Scott, President Lincoln offered Scott's fellow Virginian, Robert E. Lee, command of the Union Army. Having graduated second in his class from West Point, Lee had spent his entire career in the Army. Now at age 54, he told Scott: "Save in defense of my native state, I never desire again to draw my sword." Scott answered: "You have made the greatest mistake of your life." Lee resigned from the United States Army and became the commander-in-chief of Virginia's military forces. In May, Virginia was admitted to the Confederacy. The frontier violence that helped pull the country toward war is the subject of our episode on Bleeding Kansas.

July 21, 1861: The Battle of Bull Run

Two months later, on July 21st, 1861, the first major battle of the Civil War took place in Manassas, Virginia. The South called it the First Battle of Manassas. It was known by the North as the First Battle of Bull Run, for a stream nearby. That pattern of naming battles either by the nearest town or by the nearest body of water would remain for the duration of the war. The battlefield was a strategic location because of its proximity to the Confederate capital at Richmond and even closer proximity to the Union capital at Washington. Brigadier General Irvin McDowell commanded the Union Army of Northeastern Virginia. General P.G.T. Beauregard led the Confederate Army of the Potomac, with reinforcements under General Joseph E. Johnston.

On the Union side, about 35,000 troops were present, though not all were engaged at once. The Confederates fielded roughly 32,000 soldiers. Many of the soldiers on both sides were inexperienced volunteers who had enlisted for short terms of service. A young George Armstrong Custer, who had graduated from West Point one month earlier, fought for the Union that day. McDowell advanced into Virginia, hoping to defeat Beauregard's army before Johnston's forces could reinforce it. However, Confederate troops managed to combine their armies in time, aided by the use of railroads, one of the first times in history that rail transport played a decisive military role.

Stonewall Jackson and the Long War Ahead

Hundreds of civilians traveled from Washington to watch what they assumed would be a Union victory. Politicians, government officials, journalists, and even families arrived with picnic baskets to observe the fighting from nearby hills. Their presence reflected the widespread belief that the war would be short and perhaps even somewhat theatrical. As the battle turned against the Union and Northern troops retreated in confusion, many civilians were caught up in the chaotic flight back toward Washington. Some Northern papers prematurely reported Union success before the reality of defeat became clear.

When the full story emerged, headlines described a disastrous rout. Southern newspapers celebrated a great victory. General Thomas J. Jackson earned the nickname Stonewall for his firm stand during the fighting. President Lincoln was deeply sobered by the outcome. He now called for 500,000 additional volunteers to serve for three years. The effort to suppress Southern Rebellion was to be a prolonged and devastating war between the states. The Second Battle of Manassas would come just over a year later. The most provocative spark in the years before the war is covered in our episode on John Brown's raid on Harpers Ferry.
