After the Big Bottom Massacre took place in 1791, conflicts continued in the Northwest Indian Wars. Violent outbreaks between settlers and American Indians occurred in Kentucky and territories west of Ohio.
This continued until the aboriginal American tribes were finally defeated in the Battle of Fallen Timbers, in 1794.
Freeing slaves during the civil war led to it. As Sherman was marching to the sea, he freed numerous slaves who now became refugees and joined him in the march. He made the special order because they had to be somewhere since they didn't have any land or property.
