Erected by the American Scenic and Historic Preservation Society in 1909 (and still standing in its original location), this marker celebrates the defense of nearby Fort Tyron by Maryland and Virginia Regiment on November 16, 1776. The monument also notes the participation of Margaret Corbin, "the first American woman to take a soldier’s part in the War for Liberty." Corbin, a nurse, was allowed to accompany her husband into battle to help with the wounded. When he fell, she took over his position at the canon, firing until she too was seriously injured.

The Fort Tyron marker was funded by Cornelius Kingsley Garrison Billings and originally placed on his estate (near to the location of the battle). When the Billings estate, Tryon Hall, buried in 1926, the land was finally accepted by the city for parkland. (The owner of the estate since 1917, John D. Rockefeller had been trying to donate it to the city for years at that point). When Fort Tryon Park was laid out the marker remained and two different roads in the park were named in honor of Margaret Corbin.
