Answer 2

The War of 1812. On September 3, 1814, Francis Scott Key and John S. Skinner, an American prisoner-exchange agent, set sail from Baltimore aboard the ship HMS Minden flying a flag of truce on a mission approved by U.S. President James Madison. Their objective was to secure the release of Dr. William Beanes, the elderly and popular town physician of Upper Marlboro, a friend of Key’s who had been captured in his home. Beanes was accused of aiding in the arrest of British soldiers. Key and Skinner boarded the British flagship, HMS Tonnant, on September 7 and spoke with Major General Robert Ross and Admiral Alexander Cochrane over dinner, while they discussed war plans. At first, Ross and Cochrane refused to release Beanes, but relented after Key and Skinner showed them letters written by wounded British prisoners praising Beanes and other Americans for their kind treatment. Because Key and Skinner had heard details of the plans for the attack on Baltimore, they were held captive until after the battle, first aboard HMS Surprise, and later back on HMS Minden. After the bombardment, certain British gunboats attempted to slip past the fort and effect a landing in a cove to the west of it, but they were turned away by fire from nearby Fort Covington, the city's last line of defense. During the rainy night, Key had witnessed the bombardment and observed that the fort’s smaller "storm flag" continued to fly, but once the shelling had stopped, he would not know how the battle had turned out until dawn. By then, the storm flag had been lowered, and the larger flag had been raised. Key was inspired by the American victory and the sight of the large American flag flying triumphantly above the fort. It inspired him to write a poem about the incident that would later be put to music and become our National Anthem. Aboard the ship the next day, Key wrote a poem on the back of a letter he had kept in his pocket. At twilight on 16 September, he and Skinner were released in Baltimore. He finished the poem at the Indian Queen Hotel, where he was staying, and he entitled it "Defence of Fort McHenry."
