Colonel Josiah Harmar is given command of the First American Regiment in 1784, becoming the senior officer in the United States Army.

In a follow up to the 1784 Treaty of Fort Stanwix, where the Seneca nation had given up claims to the Ohio Country, the American government seeks a treaty with the remaining tribes having claims in the Ohio Country.

The United States sends a team of diplomats including George Rogers Clark, Richard Butler, and Arthur Lee to negotiate a new treaty at Fort McIntosh (present Beaver, Pennsylvania).
