While working on a newspaper abstraction project completely unrelated to anything Vanderbilt I happened upon this news item.
Fayetteville Observer (paper of Fayetteville, NC)
22 Jun 1857
Probable Arrest of Gen. Walker – Commodore Vanderbilt has had a capias issued for the arrest of Gen. Walker, charged with having combined with Messrs. C.K. Garrison and Charles Morgan to break up the Accessory Transit steamship line. The Commodore is, of course, well aware that General Walker’s pockets must be completely empty. He has had the writ issued as a matter of form. The effect of the writ, though not particularly remunerative of the Commodore, will probably compel the General to show himself before a New York court.
