It appears from the mortuary records of the prison that 13,000 men were
registered and buried during the year of its occupation. It also appears
from the same hospital lists that 17,873 men received medical treatment,
or were known to be sick, and their names entered in the books. Of these,
825 men were exchanged, leaving 17,048 to be accounted for; thus giving a
mortality of more than 76 per cent., or 760 men out of every thousand.
It is said, and stated with confidence, that the names of the 4000
soldiers who died in their mud-holes within the pen, and who did not
generally receive any medical treatment whatever, were placed upon the
hospital register, and their diseases diagnosed after death and removal
from the stockade. But of this the writer is not positive, although he has
seen tables of statistics of certain periods of the prison, where it is
shown that every patient who was treated for disease perished.
