In the first case he was largely instrumental in establishing a precedent, setting forth the theory that slaves brought into free territory, were at liberty. In the second case, he obtained a verdict of $500.00 damages in favor of the colored woman as against the company. The establishment of this precedent caused the street railroad companies of the city to issue an order that colored persons should be allowed to travel in their cars. Thus did Chester A. Arthur obtain equal civil rights for negroes in public vehicles.
In 1859 he married Miss Ellen Lewis Herndon, of Fredericksburg, Virginia; daughter of Captain William Lewis Herndon, United States Navy, who went bravely to his death in 1857, sinking with his ship, the Central America, refusing to leave his post of duty, though he helped secure the safety of others. Mrs. Arthur was a devoted wife, and a woman of many accomplishments. She died in January, 1880, and lies buried in the Albany Rural Cemetery.
Mr. Arthur took a lively interest in politics, and was first a Henry Clay Whig, but later helped to form the Republican party. He held several offices in the militia prior to 1860, and when Edwin D. Morgan became governor of the State in 1860, he made Mr. Arthur a member of his staff, promoting him from one position to another until he became quarter-master general. The duties of this post were most arduous and exacting. To promptly equip, supply and forward the thousands of troops sent to the front to defend the Union was a task demanding the highest executive ability and rare organizing skill, besides the greatest precision in receiving, disbursing and accounting for the public funds. Millions of dollars passed through his hands; he had the letting of enormous contracts, and opportunities, without number, by which he might have enriched himself. But he was true to himself and to his trust. So implicit was the confidence reposed in him that his accounts were audited at Washington without question or deduction, though the claims of many States were disallowed, to the extent of millions. He left the office poorer than when he entered it, but with the proud satisfaction of knowing that all the world esteemed him as an honest man.
