"Just across the Muskingum, Fort Harmar looked out over the Ohio River; its original purpose was to evict squatters and protect the Indians from the settlers."
"It is notable as the site for the 1789 Treaty of Fort Harmar between the United States and several Native American tribes."
"Harmar was the senior officer in the United States Army, from 1784 to 1791, and was given command of the First American Regiment in 1784. He signed the Treaty of Fort McIntosh in 1785, the same year that he ordered the construction of Fort Harmar near Marietta, Ohio. He also supervised the construction of Fort Steuben near present-day Steubenville, Ohio. Harmar was promoted to brigadier general in 1787. General Harmar directed the construction in 1789 of Fort Washington, Cincinnati, Ohio, which was built to protect the settlements in the Northwest Territory. The fort was named in honor of President Washington.
In 1790, Harmar was sent on expeditions against Native Americans and remaining British in the Northwest Territory. After a few initial military successes, his force of Federal troops was defeated by a tribal coalition led by Little Turtle, in an engagement known as the "Harmar's defeat", "Battle of the Maumee", Battle of Kekionga", or "Battle of the Miami Towns". Later, Harmar returned with a somewhat larger force and engaged the coalition, but fought to a draw. Consequently he was relieved of this command and replaced by General Arthur St. Clair. Harmar was subsequently court-martialed, at his own request, on various charges of negligence, and exonerated by a court of inquiry.[1]"
