"The Star-Spangled Banner"

The national anthem of the United States of America, " The Star-Spangled Banner" was set to the melody of an English drinking song. It was written in 1814 and officially decreed as the national anthem by Congress in 1931.
The lyrics to "The Star-Spangled Banner" described Francis Scott Key's impression of the battle between the British and the Americans at Fort McHenry, a fortress for Baltimore, which is 40 miles north of Washington, D.C..
When the battle ended and the smoke cleared, Key could see the red, white and blue flag still fluttering in the morning breeze - which was a sign of American victory.

These two flags are in downtown Oakland.

The information about the flag was taken from "The Intellictual Devotional- American History" written by David S. Kidder and Noah D. Oppenheim.
