Was Fort Sumner a union victory?

Fort Sumner was not a Union victory; rather, it was a Confederate victory. The fort, located in South Carolina, was besieged and captured by Confederate forces in April 1861, marking the start of the Civil War. The fall of Fort Sumter galvanized the North and led to a surge of enlistments for the Union Army. Thus, while it was a significant event for the Confederacy, it ultimately rallied the Union to fight back.
