1875 even President Grant admitted that Louisiana's 1872 election "was a gigantic fraud, and there are no reliable returns of its result." According to historian William Gillette, "By having invoked federal authority in civil law and having employed federal force in state politics, he [Grant] had mounted a successful coups d'état." Warmoth was impeached for allegedly stealing the election. A black Republican, P. B. S. Pinchback, became governor for 35 days until Grant seated Kellogg as Governor with Federal protection. McEnery's faction established a "rump legislature" in New Orleans to oppose Kellogg's actions. McEnery urged his supporters to take up arms against Kellogg's fraudulent government.
