What was Dolly role in the war of 1812?

There seems to be a misunderstanding. "Dolly" doesn't refer to a person who participated in the War of 1812.

Are you perhaps thinking of Dolley Madison, the First Lady during the presidency of James Madison? She played a significant role during the War of 1812, especially during the burning of Washington, D.C.

Let me know if you'd like to know more about Dolley Madison's actions during the War of 1812.
