After Schofield's departure to become U.S. Secretary of War under President
Andrew Johnson, and Reconstruction ended in Virginia after voters approved a new state constitution (but not certain anti-Confederate provisions), the new
Virginia General Assembly passed a law allowing the newly elected governor,
Gilbert C. Walker, to appoint members of the Richmond city council. He only reappointed three Republicans, and the new
Conservative-dominated Council chose publisher
Henry K. Ellyson to become the city's mayor on March 16, 1870. Chahoon and some of his Republican allies, including the police commissioner Poe, refused to leave office. For about two months, Richmond had two mayors and two police forces. Ellyson's supporters besieged Chahoon and his allies, who had barricaded themselves in the main police station, until they were rescued by federal troops sent by General
Edward Canby, only to take over another police station. In separate skirmishes, one black Republican and one German Catholic deputy (both never named in published accounts) were killed. Governor Walker formally contested the federal action. Chahoon and Ellyson also wanted courts to decide which was the legitimate administration. The federal judges (Underwood and the applicable circuit justice,
Salmon P. Chase) deferred to the
Virginia Supreme Court of Appeals. That court announced that it would render its opinion on April 27, 1870, in its upstairs courtroom within the
Virginia State Capitol. The overcrowded gallery collapsed just before the judges entered, which caused the courtroom floor to collapse into the chamber of the House of Delegates below. Amidst the dust and chaos, initial estimates were that about 75 men had died and 500 more injured, among them Chahoon and Ellyson. The appeals court ultimately ruled in Ellyson's favor two days later, but also set a new election for May. Then the men carrying the ballots from pro-Chahoon
Jackson Ward were robbed of those completed ballots, and the Conservative-dominated Board of Elections declared Ellyson the winner based on the other wards' countable ballots. However, Ellyson refused to continue in the circumstances, necessitating yet another election, which Chahoon lost to New-Jersey born former Confederate and publisher
Anthony M. Kieley. Conservatives then sent Chahoon to prison on a forgery charge relating to real estate, after he was convicted by three juries (two verdicts having been overturned on appeal, and the third jury recommended clemency). Governor Walker, a fellow native New Yorker, pardoned Chahoon on December 16, 1871, reputedly on the condition that he leave the Commonwealth. ==New York career and politics==
