As they had in Florida and the Indian Territory, the blacks and Indians split
into separate communities. The blacks temporarily settled at El Moral, 20 miles
north of Piedras Negras. Emphasizing their separateness, the Black Seminoles
received their own distinct Spanish name, “los mascogos.” The etymology is
unknown but almost certainly derived from “Muskogee,” the old Native American
term used to describe members of the Creek confederacy, from which the Seminoles
had seceded in Florida.
The emigrants subsided on rations, having arrived too late to plant crops. Their
situation was still fortunate compared to the plight of their companions back in
the Indian Territory.
