"Deportation" implies forced expulsion. Lincoln considered resettlement of freed slaves in Africa, Latin America, or the Caribbean (as many Americans of his day did), but there's no indication that it was ever expected to be anything other than voluntary.
Lincoln's late support for citizenship and the vote for African-Americans who had served in the war (and his closer relations with Frederick Douglas and other Black notables) strongly suggests that he'd given up ideas of recolonization on any major scale.
Right. Lincoln explored voluntary emigration - not forced deportation as the article implies.
He was correct.
