During which battle were Congreve rockets famously used?

The use of Congreve rockets is famously associated with the Battle of Fort McHenry, which took place in September 1814 during the War of 1812. These rockets were an innovative artillery technology developed by Sir William Congreve and were designed to be fired from a rocket launcher. Their usage at Fort McHenry was significant as part of the British bombardment of the fort, which was defending Baltimore Harbor.

The notable aspect of this battle is that it inspired Francis Scott Key to write "The Star-Spangled Banner," as he witnessed the intense bombardment and saw the American flag still flying over the fort at dawn. The effectiveness and dramatic impact of the Congreve rockets during this battle contributed to their historical significance, leading to their lasting legacy in American symbolism and military history.
