sentences:  John Horse, who was the son of a slave mother and an Indian father, was nominally a slave under both American and Seminole law until finally being freed by the American military for his service to the army in Florida after his return there at the military's request.He was later officially set free of any Seminole claims on his person by Chief Micanopy, titular head of all the Seminole bands, for his service to the Indians.When the Africans living among the Seminole continued to face threats of re-enslavement in their new home, thanks to the connivance of some American officials (despite Jesup's decree emancipating all surrendering escaped African slaves), John Horse would once again join forces with his old comrade, Wildcat, to lead a group of disaffected Seminole and former slaves across the Rio Grande to northern Mexico where they were granted land by the Mexican government in 1850 and where the Seminole blacks could finally be assured of their freedom, Mexico having abolished legal slavery in the 1820s.
