During the French and Indian Wars, Seven Years' War and the American Revolution, Schuyler Flatts was used for staging of the troops, lodging for women and children as their men were at war, and tending to the sick and injured in the large barn that was outfitted as a hospital, where Schuyler and other women could tend to up to 500 soldiers.
