Trivia question for this Flag Day: How big was the Garrison Flag that flew above Baltimore's Fort McHenry during the War of 1812 and inspired the writing of the national anthem? Answer: The Garrison Flag was 30 feet tall by 42 feet wide and required 400 yards of fabric. It weighed 50 pounds and required 11 men to hoist it up a 90-foot flagpole as the British fleet sailed away from Fort McHenry on September 14, 1814. See how you measure up against the stars and stripes of the "Great Garrison Flag" in "The Unfinished Revolution: Maryland in the Wars for Independence" exhibition. "...it is my desire to have a flag so large that the British will have no difficulty in seeing it from a distance.” — Major George Armistead to Samuel Smith, July 1813 #MarylandHistory #MDHistory #AmericanRevolution #Warof1812 #BattleofBaltimore #GreatGarrisonFlag #GarrisonFlag #BigFlag #FortMcHenry #FlagDay
