Compléter The Star-Spangled BannerVersion en ligne "The Star-Spangled Banner" is the national anthem of the United States. The lyrics come from the "Defence of Fort M'Henry",[2] a poem written on September 14, 1814, by 35-year-old lawyer and amateur poet Francis Scott Key after witnessing the bombardment of Fort McHenry by British ships of the Royal Navy in Baltimore Harbor during the Battle of Baltimore in the War of 1812. Key was inspired by the large U.S. flag, with 15 stars and 15 stripes, known as the Star-Spangled Banner, flying triumphantly above the fort during the U.S. victory. The poem was set to the tune of a popular British song written by John Stafford Smith par Oscar Cabanillas 1 gleaming stripes silence seen rocket's spangled streaming hailed ramparts brave O say can you see , by the dawn's early light , What so proudly we at the twilight's last , Whose broad and bright stars through the perilous fight , O'er the we watched , were so gallantly ? And the red glare , the bombs bursting in air , Gave proof through the night that our flag was still there ; O say does that star - banner yet wave O'er the land of the free and the home of the ? On the shore dimly through the mists of the deep , Where the foe's haughty host in dread reposes , What is that which the breeze , o'er the towering steep , As it fitfully blows , half conceals , half discloses ? Now it catches the gleam of the morning's first beam , In full glory reflected now shines in the stream : 'Tis the star - spangled banner , O long may it wave O'er the land of the free and the home of the brave .
