"Of 115,000 Russians who invaded Turkey in 1828 and 1829, only 10,000 or 15,000 ever repassed the Pruth. The rest died there of intermittent fevers, dysenteries, and plague." "From May, 1828, to February, 1829, 210,108 patients were admitted into the general and regimental hospitals." "In October, 1828, 20,000 entered the general hospitals." "The sickness was very fatal." "More than a quarter of the fever-patients died." "5,509 entered the hospitals, and of these, 3,959 died in August, 1829, and only 614 ultimately recovered." "At Brailow the plague attacked 1,200 and destroyed 774." "Dysentery was equally fatal." "In the march across the Balkan, 1,000 men died of diarrhoea, fever, and scurvy." "In Bulgaria, during July, 37,000 men were taken sick." "At Adrianople a vast barrack was taken for a hospital, and in three days 1,616 patients were admitted. On the first of September there were 3,666, and on the 15th, 4,646 patients in the house. This was one-quarter of all the disposable force at that station." "In October, 1,300 died of dysentery; and at the end of the month there were 4,700 in the hospitals." "In the whole army the loss to the Russians in the year 1829 was at least 60,000 men."[21] CRIMEAN WAR. In 1854, twenty-five years after this fatal experience of the Russian army in Bulgaria, the British Government sent an army to the same province, where the men were exposed to the same diseases and suffered a similar depreciation of vital force in sickness and death. For two years and more they struggled with these destructive influences in their own camps, in Bulgaria and the Crimea, with the usual result of such exposures in waste of life. From April 10, 1854, to June 30, 1856, 82,901 British soldiers were sent to the Black Sea and its coasts; and through these twenty-six and two-thirds months the British army had an average of 34,559 men engaged in that "War in the East" with Russia. From these there were furnished to the general and regimental, the stationary and movable hospitals 218,952 cases: 24,084, or 11 per cent, of these patients were wounded or injured in battle, and 194,868, or 89 per cent, suffered from the diseases of the camp. This is equal to an annual average of two and a half attacks of sickness for each man. The published reports give an analysis of only 162,123 of these cases of disease. Of these, 110,673, or 68 per cent., were of the zymotic class,--fevers, dysenteries, scurvy, etc., which are generally supposed to be due to exposure and privation, and other causes which are subject to human control. During the two years ending with March, 1856, 16,224 died of diseases, of which 14,476 were of the zymotic or preventable class, 2,755 were killed in battle, and 2,019 died of wounds and injuries received in battle. The annual rate of mortality, from all diseases, was 23 per cent; from zymotic diseases, 21 per cent.; from battle, 6.9 per cent. The rate of sickness and mortality varied exceedingly in different months.
