From Ohio History Central
In 1789, Fort Washington was built to protect early settlements located in the Symmes Purchase in the Miami Valley of what is now southwestern Ohio. The fort was located in modern-day Cincinnati and protected settlers of that city in its early years from retalitation by American Indians already living in the area. General Josiah Harmar described it as "one of the most solid substantial wooden fortresses. . .of any in the Western Territory." The stockade's walls were two stories high with blockhouses located at each corner. The fort was named in honor of President George Washington. In 1790, Harmar used Fort Washington to launch an expedition against the Miami whose principal city was Kekionga (modern-day Fort Wayne, Indiana). The fort would serve similar purposes for the remainder of the 1790s until the United States Army abandoned it in 1803.
