Answer:
Step-by-step explanation:
During the War of 1812, Francis Scott Key was a lawyer and really had no major role in the war.
However, one night in 1814, his friend was taken hostage by the British. He found the ship in Baltimore, but they weren't allowed to leave until after the battle.
In this Battle at Fort McHenry, the British launched a massive bombing campaign against the United States, but they managed to fend it off.
The next day, the British stopped. Francis Scott Key witnessed the battle and noticed was one American flag still flying. He wrote a poem called the Star Spangled Banner and it became the National Anthem in 1931.
So, he was inspired by the Battle at Fort McHenry
