Reconstruction governments. Using the powers of the Enforcement Acts, Grant crushed the Ku Klux Klan. By October, Grant suspended habeas corpus in part of South Carolina and sent federal troops to help marshals, who initiated prosecutions. Grant's Attorney General, Amos T. Akerman, who replaced Hoar, was zealous to destroy the Klan. Akerman and South Carolina's U.S. marshal arrested over 470 Klan members, while hundreds of Klansmen, including the wealthy leaders, fled the state. By 1872 the Klan's power had collapsed, and African Americans voted in record numbers in elections in the South. Attorney General George H. Williams, Akerman's replacement, in the Spring of 1873, suspended prosecutions of the Klan in North Carolina and South Carolina, but prior to the election of 1874, he changed course and prosecuted the Klan. During Grant's second term, the North retreated from Reconstruction, while southern conservative whites called "Redeemers" formed armed groups, the Red Shirts and the White League, who openly used violence, intimidation, voter fraud, and racist appeals to overturn Republican rule. Northern apathy toward blacks, the depressed economy and Grant's scandals made it politically difficult for the Grant administration to maintain support for Reconstruction. Power shifted when the House was taken over by the Democrats in the election of 1874. Grant ended the Brooks–Baxter War, bringing Reconstruction in Arkansas to a peaceful conclusion. He sent troops to New Orleans in the wake of the Colfax massacre and disputes over the election of Governor William Pitt Kellogg. Grant recalled Sheridan and most of the federal troops from Louisiana. By 1875, Redeemer Democrats had taken control of all but three Southern states. As violence against black Southerners escalated once more, Grant's Attorney General Edwards Pierrepont told Republican Governor Adelbert Ames of Mississippi that the people were "tired of the autumnal outbreaks in the South", and declined to intervene directly, instead of sending an emissary to negotiate a peaceful election. Grant later regretted not issuing a proclamation to help Ames, having been told Republicans in Ohio would bolt the party if Grant intervened in Mississippi. Grant told Congress in January 1875 he could not "see with indifference Union men or Republicans ostracized, persecuted, and murdered." Congress refused to strengthen the laws against violence but instead passed a sweeping law to guarantee blacks access to public facilities. Grant signed it as the Civil Rights Act of 1875, but there was little enforcement and the Supreme Court ruled
