With this brief and bald complaint for trespass to the person and false imprisonment was begun a long and stubbornly fought litigation, extending over ten years, and which was destined to end in Chief Justice Taney declaring: They [negroes] had for more than a century before [the Declaration of Independence] been regarded as beings of an inferior order, and altogether unfit to associate with the white race, either in social or political relations; and so far inferior that they had no rights which the white man was bound to respect; and that the negro might justly and lawfully be reduced to slavery for his benefit. He was bought and sold and treated as an ordinary article of merchandise and traffic whenever a profit could be made by it. From the beginning of his connection with this case Roswell Field contended for the broad principle enunciated by Lord Mansfield that "Slavery is so odious that nothing can be suffered to support it but positive law." He consented to a discontinuance of the original action because of the variance of the complaint from the subsequently discovered facts. In the second suit Dred Scott and his family were declared free by the local court, but the judgment was reversed on appeal to the Supreme Court of the state. Judge Gamble, in dissenting from the opinion of the majority of the Court, held that "In Missouri it has been recognized from the beginning of the Government as a correct position in law that a master who takes his slave to reside in a state or territory where slavery is prohibited thereby emancipates his slave." The subsequent sale of Dred Scott to a citizen of New York named Sandford afforded Roswell Field the opportunity to renew the fight for Scott's freedom in the United States Circuit Court at St. Louis. The case was tried in May, 1854, and it was again declared that Scott and his family "were negro slaves, the lawful property of Sandford." Roswell Field immediately appealed by writ of error to the Supreme Court of the United States, where the appeal was first argued early in 1856, and a second time in December of the same year. Mr. Field's connection with the case ended when he prepared the papers on appeal and sent his brief to Montgomery Blair, with whom was associated for Scott on the second hearing George Ticknor Curtis. Both of these eminent lawyers emulated the example of Eugene Field's father, who for nearly nine years had devoted a large share of his time and energy to the fight of a penniless negro slave for liberty.
