Mullaly was a controversial figure during the
American Civil War, one of New York City's ardent opponents to the draft. On August 19, 1864, John Mullaly was arrested for inciting
resistance to the draft and examined a few days later for possible trial. At a rally in Union Square on May 19, 1863, Mullaly declared the war to be “wicked, cruel and unnecessary, and carried on solely to benefit the negroes”, and advised resistance to conscription if ever the attempt should be made to enforce the law. As editor of the Metropolitan Record, Mullaly's call for armed resistance to the military draft led to his arrest following the July 1863
New York City Draft Riots. Over one hundred people died, including Black men beaten to death or lynched by rioters, in the worst urban unrest in the United States during the 19th century. A racist, Mullaly did not support the murder of Blacks during the rioting. In one Metropolitan Record editorial he advised members of the “superior” race not to turn their anger against an “inferior” one. Editorials in the Metropolitan Record written by Mullaly leading up to the Draft Riots accused the Lincoln Administration of perverting the war from an attempt to restore the Union into an "emancipation crusade." He charged the “vile and infamous"
Emancipation Proclamation would bring "massacre and rapine and outrage into the homes on Southern plantations, sprinkling their hearths with the blood of gentle women, helpless age, and innocent childhood." According to Mullaly's diatribe, "Never was a blacker crime sought to be committed against nature, against humanity, against the holy precepts of Christianity." In the indictment, Mullaly was also charged with counseling Governor Seymour to "forcibly to resist an enrollment ordered by competent authority in pursuance of said act of Congress." After a hearing, however, the case against Mullaly was discharged. == Developer of parks in The Bronx ==
