why was the civil wars first large battle the first battle of bull run so shocking

The First Battle of Bull Run, fought on July 21, 1861, was the first large-scale battle of the American Civil War. It was particularly shocking for several reasons:

1. Inexperience of troops: Both the Union and Confederate armies consisted of inexperienced soldiers who had not seen much combat. Many of them saw the war as an opportunity for a quick, decisive victory. However, the battle revealed the realities of war as they faced cruel and brutal combat.

2. Popular expectation of a swift victory: The battle was anticipated to be a quick and decisive Union victory. Many northerners traveled to watch the spectacle, bringing picnic baskets and cheering for their side. However, the battle shattered these expectations, as it became apparent that the war would be long and devastating.

3. Casualties and loss of life: The casualties at the First Battle of Bull Run were higher than expected, with almost 5,000 total casualties. This shocked the public as they realized the true human cost of the conflict. It dispelled the notion that the war would be a quick and bloodless triumph.

4. Panic and retreat: The Union troops, after initial success, lost control and began to retreat in disarray. This triggered a panic and rout among Union soldiers. The sight of retreating soldiers and the chaos on the battlefield surprised and shocked many observers, highlighting the unpreparedness and lack of discipline among the Union forces.

5. Political implications: The defeat at Bull Run had significant political implications. The Union government had believed the war would be a swift victory, but this defeat exposed the need for better organization, training, and leadership. It also boosted the confidence of the Confederacy and their belief in their ability to defend their cause.

In summary, the First Battle of Bull Run was shocking due to the inexperience of troops, the shattered expectations of a swift victory, high casualties, panic and retreat among Union troops, and the political implications it carried. It served as a wake-up call for both sides, highlighting the grim reality of the war.
