On the 21st of April, 1864, a law was enacted in New York State called "an act to enable the qualified electors of this State, absent therefrom in the military service of the United States, in the Army or navy thereof, to vote."
This law provided for a power of attorney appointing a proxy who would present his (the soldier's) sealed envelope, addressed to the election inspectors in his home or residence district. The ballot was to be in a sealed envelope, and to be opened only by the inspectors; this envelope was to be enclosed in another, outer envelope addressed to his proxy. The outer envelope was to contain also the power of attorney for the proxy to so present the sealed ballot.
And now I will tell you how merely the misplacing of the letter "L" betrayed one of the greatest crimes of the period, entirely defeated its perpetration, and helped to save our Union.
On Thursday afternoon, October 20th, 1864, General Wallace came to my office with Mr. Orville K. Wood, of Clinton county, New York.
Mr. Wood had a blank or partly blank document which he had found in possession of a soldier from his county. It was a blank power of attorney, such as were provided for voting under the law of April 21st, 1864. The jurat was signed in blank:
C. G. Arthur
Lieut. 11th U. S. Cavl.
—and their conclusion was that this officer may have signed a number of such papers in blank, and passed them out, to be used by any soldier, perhaps to facilitate voting; an illegal act in itself; but upon examination I pronounced the officer's signature a forgery. My conclusion was based on the fact of the letter "l" in "Cavl." I assumed that no officer of cavalry, more especially in the regular service, would abbreviate in any way other than Cav. or Cavy.
General Wallace saw the force of my reasoning, and a new light was thrown on the matter.
Had the one letter "l" been absent I should have concluded as General Wallace and Mr. Wood had, i. e., that the fact of such a document, entirely blank except the officer's jurat, being in public hands, was a wrong merely laying the officer liable for having attached his name to a blank paper.
