It has seemed to me that there should be a history of the development, the revolt, and the tragedy of Anarchy in Chicago. This history I have written as impartially and as fairly as I knew how to write it. I have kept steadily before my eyes the motto,— “Nothing extenuate, nor set down aught in malice.” It will be found in the succeeding pages that neither animosity against the revolutionists, nor partiality to the State, has influenced the work. I have dealt with this episode in Chicago's history as calmly and as fairly as I am able. I have tried to put myself in the position of the misguided men whose conspiracy led to the Haymarket explosion and to the gallows; to understand their motives; to appreciate their ideals—for so only could this volume be properly written. And to present a broader view, I have added a history of all forms of Socialism, Communism, Nihilism and Anarchy. In this, though necessarily brief, it has been the purpose to give all the important facts, and to set forth the theories of all those who, whether moderate or radical, whether sincerely laboring in the interests of humanity or boisterously striving for notoriety, have endeavored or pretended to improve upon the existing order of society. After the dynamite bomb exploded, carrying death into the ranks of men with whom I had been for years closely associated—after an impudent attack had been made upon our law and upon our system, which I was sworn to defend—it came to me as a duty to the State, a duty to my dead and wounded comrades, to bring the guilty men to justice; to expose the conspiracy to the world, and thus to assist in vindicating the law. How the duty was performed, this story tells. It is a plain narrative whose interest lies in the momentous character of the facts which it relates. Much of it is now for the first time given to the public.
