At the end of the Second American Revolution, Congressman Oldham sponsored a bill to expel or reenslave all free Negroes in the Confederacy. Shortly afterwards, he bought a fine house in Richmond which he paid for in gold. Robert E. Lee knew that the Rivington Men were behind it but was uncertain as to what end they schemed.
