I watched a Gun smoke episode yesterday. The scenario was that Chief Joseph of the Nez Perce was heading to Washington for a meeting with the president about being allowed back on their land. It was 1879 when Joseph went to Washington. In the story Joseph is sick , Doc pulls him through and there is a local who stirs up the town folk because his brother was killed in the Nez Perce war (June to October 1877). Just as things are getting hot , Matt received a telegraph from DC saying that Joseph is under the protection of the US government. It is signed by President Grant , who left office in March of 1877 . So is this just sloppy research by the Gun smoke writers or did Grant serve as shadow president during Rutherford Hayes's tenure? As a crossover from another thread , was Grant aware that Booth survived the war and moved to India?
