From a Seneca County, New York newspaper in January 1865:
STATISTICS OF LIBBY PRISON. – An army of harmless Yankees have passed through Richmond within the year just expiring. – From the statistics of the clerk of Libby Prison, Mr. Ross, we learn that from the first of January, 1864, to the 19th of December, of the same year, 31,630 yankee prisoners, of all grades, nations, tongues, complexions and kindreds, passed the doors of Libby, as Prisoners of war. This number is independent of about twenty thousand captured at Spottsylvania and elsewhere in Virginia, who were sent South without touching Richmond. Since the war began 250,000 men have passed the doors of the Libby, and departed as prisoners of war. – Richmond Paper.
The harmless Yankees were still occupying the Libby in the New Year. From the Richmond Daily Dispatch January 9, 1865:
Arrival of prisoners.
–Ninety-two Yankee prisoners, including two commissioned officers, captured recently in Southwestern Virginia, arrived in this city on Saturday, and were committed to the Libby prison.
