One of the significant challenges faced by the Union during the Battle of Fort Sumter was the overwhelming Confederate numbers. The Confederate forces, under the command of Brigadier General P.G.T. Beauregard, were well-prepared and had established a strong artillery position around the fort. This numerical advantage allowed them to bombard Fort Sumter effectively, while Union troops, led by Major Robert Anderson, were severely outnumbered and lacked adequate reinforcements. The disparity in troop strength contributed to the fort's vulnerability and its eventual surrender, highlighting the critical role that numbers played in early military engagements during the Civil War.
