From the Richmond Enquirer, 7/19/1862, p. 1, c. 7
THE PRISONERS. – The number of prisoners who had arrived in the city at the time of the publication of the official report in the "Enquirer," a few days subsequent to the last of the recent series of battles below Richmond, was about four thousand. We stated at the time that several thousand more were on the road and in the hospitals below the city. Nearly all of these have now been brought in and sum up about four thousand more, making an aggregate of about eight thousand. Three thousand of these are still in the Libby prison, and the remainder have been removed to the camp at Belle Isle. When the returns shall have been complete, it will be found that our estimate some time ago was very nearly the figure, or upwards of nine thousand.
