Document 3: Star-Spangled Banner (flag): The Star-Spangled Banner, or the Great Garrison Flag, was the garrison flag that flew over Fort McHenry in Baltimore Harbor during the naval portion of the Battle of Baltimore during the War of 1812. Seeing the flag during the battle inspired Francis Scott Key to write the poem "Defence of Fort M'Henry", which, retitled with the flag's name from the closing lines of the first stanza and set to the tune of "To Anacreon in Heaven" by John Stafford Smith, later became the national anthem of the United States.
Document 4: Brown's Brewery: Brown's Brewery was a brewery located on East Lombard Street in Baltimore, Maryland. In 1813, Mary Pickersgill sewed the famous Star Spangled Banner Flag in one of its malthouses. At the time, the brewery was owned by Baltimore merchant George I. Brown who had bought it from Edward Johnson, the third Mayor of Baltimore. George Brown sold the brewery to Eli Claggett in 1818, and until its final closure in 1879, it was known as Claggett's Brewery. The site once occupied by the brewery was excavated in 1983 as the Baltimore Center for Urban Archeology's first project.
Document 5: Battle of North Point: The Battle of North Point was an engagement in the War of 1812, fought on September 12, 1814, between Brigadier General John Stricker's Third Brigade (Baltimore City Brigade) of the Maryland State Militia and a British landing force, composed of units from the King's Army (British Army), Royal Navy seamen, Colonial Marines, Royal Marines, and led by Major General Robert Ross and Rear Admiral George Cockburn. The events and result of the engagement, a part of the larger Battle of Baltimore, saw the U.S. forces retreating after having inflicted heavy casualties on the British.
Document 6: Francis Scott Key: Francis Scott Key (August 1, 1779January 11, 1843) was an American lawyer, author, and amateur poet from Frederick, Maryland and later Georgetown, D.C., near Washington, D.C. who wrote the lyrics for a poem entitled at first "The Defence of Fort McHenry", which when set to an old English gentlemens' society tune, eventually became the United States' national anthem, "The Star-Spangled Banner".
Document 7: Battle of Sewell's Point: The Battle of Sewell's Point was an inconclusive exchange of cannon fire between the Union gunboat USS "Monticello", supported by the USS "Thomas Freeborn", and Confederate batteries on Sewell's Point that took place on May 18, 19 and 21, 1861, in Norfolk County, Virginia in the early days of the American Civil War. Little damage was done to either side. By the end of April 1861, USS "Cumberland" and a small number of supporting ships were enforcing the Union blockade of the southeastern Virginia ports at the southern end of the Chesapeake Bay and had captured several ships which attempted to pass the blockade. USS "Monticello's" bombardment of the Sewell's Point battery was one of the earliest Union Navy actions against Confederate forces during the Civil War. While it has been suggested by some sources that the "Monticello's" action may have been the first gunfire by the Union Navy during the Civil War, a brief exchange of cannon fire between the U.S. gunboat USS "Yankee" and shore batteries manned by Virginia volunteer forces which had not yet been incorporated into the Confederate States Army at Gloucester Point, Virginia on the York River occurred on May 7, 1861.
Document 8: Amelia Fowler: Amelia Fowler, an embroidery teacher and well-known flag preserver, was the master needle worker who restored the original Star Spangled Banner in 1914. By that time, the flag that inspired Francis Scott Key to write the United States national anthem was just "a frail piece of bunting." But Fowler called upon her patented preservation techniques to save it from further deterioration. She used dyed-to-match silk thread and employed ten assistants to reinforce the 1020 sqft relic. They anchored it onto Irish linen with 1.7 million of Fowler's special honeycomb patterned, six-sided stitches. It took eight weeks to finish the preservation process. Upon completion, she claimed the restored flag would "defy the test of time," and charged the government $1,243.
Document 9: Mary Young Pickersgill: Mary Pickersgill (born Mary Young; February 12, 1776 – October 4, 1857), was the maker of the Star Spangled Banner Flag hoisted over Fort McHenry during the Battle of Baltimore in the War of 1812. The daughter of another noted flag maker, Rebecca Young, Pickersgill learned her craft from her mother, and, in 1813, was commissioned by Major George Armistead to make a flag for Baltimore's Fort McHenry that was so large that the British would have no difficulty seeing it from a great distance. The flag was installed in August 1813, and, a year later, during the Battle of Baltimore, Francis Scott Key could see the flag while negotiating a prisoner exchange aboard a British vessel, and was inspired to pen the words that became the United States National Anthem.
