During the civil war, what was one advantage the confederacy had over the union? it controlled vicksburg and other forts. it had a fleet of armored gunboats. it outnumbered the union troops. it had the support of european nations.

The right answer is indeed the A: The Confederacy controlled Vicksburg and other forts, such as Fort Henry and Fort Donelson, located in the states of Mississippi, Tennessee and Kentucky. The capture of these important Confederate strongholds by the Union troops was, nevertheless, a significant turning point in the Civil War.  

Europe did not recognize the Confederacy; the Union controlled the navy and had a large fleet of gunboats; and, even though the Confederacy had a comparable army during the first year of the war, it soon lacked sufficient men that could fight.
