No exact percentage of mortality for the seventeen years during which the prison was occupied can be given, the records being incomplete, and the population of the prison changing continually from week to week and month to month, owing to the accession of fresh prisoners and the departure of others, due to death, transference to other prisons, or exchange. The reports to the Commissioners for the sick and hurt, except in the incomplete bundles of certificates, do not appear until the second period of the war, although the sick and hurt passed at once under the care of this Board as soon as they ceased to be prisoners in health. The actual number of deaths certified is 1,770, of which 1,000 occurred during the epidemic 1800–01, the remainder being distributed over the remaining fifteen years in which the prison was occupied. It is possible that the original register kept at this prison before the Peace of Amiens, 1797–1802, might have been sent to France and may yet be found, but at present separate bundles of single certificates are for many years the only records from which these figures are obtained. The total number of deaths registered of French prisoners who died at Norman Cross in the second period of the war, 1803–14, was 559. The highest number recorded in any one year, was 98 in 1806. The lowest, in any complete year, was 18 in 1804. One of those whose death is recorded in that year is a boy of ten, a native of Bordeaux, captured on a privateer; he died of consumption. The diseases, phthisis, hæmoptysis, scrophula, which appear again and again under the heading “Cause of Death,” were all, as well as many of those entered as catarrh and debility, tubercular diseases, due to the condition so favourable to contagion in which the prisoners slept, herded together in closely packed chambers, ventilated very imperfectly. In all probability, in cold weather, every aperture by which fresh air could enter was closed by the inmates themselves, who would not be imbued with twentieth-century ideas as to the need of fresh air. Putting on one side the tubercular cases and the rare epidemics, there was comparatively little sickness among the prisoners. When an epidemic occurred, “Les Misérables,” whose powers of resistance had been lowered by the semi-starvation which they had brought upon themselves, naturally sickened and in too many instances succumbed.
