"The Star-Spangled Banner" is known by all, treasured for its powerful melody and stirring lyrics. And yet, only about 40% of U.S. citizens know all the words. And even fewer know their meaning.

We examine the battle that inspired witness Francis Scott Key to immortalize its final moments, then reveal how his poem transformed into an anthem.
