The Star-Spangled Banner Flag-- Part 1: The Great Garrison Flag

From Wikipedia.

The Star-Spangled Banner Flag is also referred to as the Great Garrison Flag and flew during the naval portion of the Battle of Baltimore.  This is the flag that inspired Francis Scott Key to write his poem "Defence of Fort McHenry."

This was retitled using words near the end of the first stanza.  It was set to music to the tune of "To Anacreon in Heaven" by John Stafford Smith.

When it became apparent that the British were going to attack Baltimore, the fort's commander, Major George Armistead expressed the desire for a very large flag to fly over the fort.

General John S. Stricker and Commodore Joshua Barney placed an order with a prominent Baltimore flagmaker to make two large flags.
