Why was it important for the flag to keep flying over fort McHenry?

The flag flying over Fort McHenry was a symbol of resilience and national pride during the War of 1812, particularly after the British bombardment of the fort in September 1814. Its survival represented the determination of American forces to defend their territory and ideals. The sight of the flag inspired Francis Scott Key to write "The Star-Spangled Banner," which later became the national anthem, solidifying its significance in American history as a symbol of unity and perseverance.
