The correct choice is the first: The Union realized that victory would not be as easy as it originally thought.

Explanation: The First Battle of Bull Run (First Manassas, July 21, 1861) was a Confederate victory that shattered Northern hopes of a short, decisive campaign. Heavy casualties, a chaotic Union retreat, and the realization that the Confederacy was well-led and determined convinced Northern leaders to mobilize more troops, reorganize and train armies (creating the Army of the Potomac), and adopt a longer-term strategy for a protracted war.
