Francis Scott Key witnessed the British bombardment of Fort McHenry in Baltimore Harbor on September 13-14, 1814, during the War of 1812. Detained on a British ship during the attack, he watched through the night as the fortress endured relentless cannon fire. When dawn broke and the American flag still flew over the fort, Key was moved to compose the poem "Defence of Fort McHenry," which he later set to the melody of a popular British song called "To Anacreon in Heaven."
Key's words captured a pivotal moment in American history and transformed a patriotic poem into one of the nation's most recognizable songs. For music educators, understanding Key's context enriches student interpretation of the text and deepens their connection to this enduring piece of American musical heritage.
