The Confederacy's victory proved detrimental to the Confederacy's cause

The Confederacy's victory proved detrimental to the Confederacy's cause. As a result of the Union's decisive victory over the Confederacy in the Civil War, American power and influence abroad increased.

The Union's cause was greatly advanced by the Battle of Fort Fisher, despite the fact that it occasionally gets lost among the last conflicts in the closing months of the war. Within a month of the Union's triumph at Fort Fisher, the Federals were able to seize Wilmington, the last significant Confederate port. The Confederacy had few supplies while the Union secured another supply route to the sea thanks to Union forces capturing Wilmington. After losing Wilmington, the Confederacy and General Robert E. Lee battled with their little supplies and eventually capitulated.
