What happened 1790 AD

In 1790, Washington sent Brigadier General Josiah Harmar to pacify the Northwest tribes, but Little Turtle routed him twice and forced him to withdraw. The Western Confederacy of tribes used guerrilla tactics and were an effective force against the sparsely manned American Army. Washington sent Major General Arthur St. Clair from Fort Washington on an expedition to restore peace in the territory in 1791. On November 4, St. Clair's forces were ambushed and soundly defeated by tribal forces with few survivors, despite Washington's warning of surprise attacks. Washington was outraged over what he viewed to be excessive Native American brutality and execution of captives, including women and children.

In 1790, Banneker prepared an ephemeris for 1791, which he hoped would be placed within a published almanac. However, he was unable to find a printer that was willing to publish and distribute the work.

In the Southwest, negotiations failed between federal commissioners and raiding Indian tribes seeking retribution. Washington invited Creek Chief Alexander McGillivray and 24 leading chiefs to New York to negotiate a treaty and treated them like foreign dignitaries. Knox and McGillivray concluded the Treaty of New York on August 7, 1790 in Federal Hall, which provided the tribes with agricultural supplies and McGillivray with a rank of Brigadier General Army and a salary of $1,500.
