Union forces retreated to Fort Monroe after the battle.

After the Battle of Fort Sumter, Union forces retreated to Fort Monroe, located in Virginia. This strategic fortification served as a critical stronghold for the Union in the early stages of the Civil War. Fort Monroe provided a haven for Union troops following their withdrawal from Fort Sumter, which had been heavily damaged and surrendered to Confederate forces. The fort's location allowed for easy access to the Chesapeake Bay, facilitating troop movements and supply routes. Fort Monroe later played a significant role in various military operations throughout the war, becoming an important site in the conflict between the North and South.
