You guessed it – it’s a military button. The button is a Regiment of Artillerists, 2nd Regiment button dating to c. 1811-1813.
A brief history of Fort McHenry
While Fort McHenry was an important naval base during the American Revolution and the site where the Star Spangled Banner was written, it was also used after the American Revolution and during the War of 1812.
The above button, which dates to c. 1811-1813, is a prime example of the continual use of archeological sites. While a site may be interpreted to a specific period, this does not mean that important events did not happen before or after the period of interpretation. This button helps remind people of the continued importance of Fort McHenry in shaping the history of America
Regiment of Artillery
The first Regiment of Artillery was created in 1791, though the official date of origin is April 12, 1808. The Regiment of Artillery was used in the War of 1812 to fight against the British, and was made famous by their defence of Fort Bowyer in Alabama. After the war, the regiment was merged into the Corps of Artillery.
