In Bender, situated in Bessarabia on the Dniester, there was a mild epidemic of bubonic plague after the city had been stormed on September 16, 1770. The carrying-off of war-booty caused new pestilences in the army and in the population of Podolia and Little Russia. For a short time in the last part of September the main army also suffered from plague in its fixed quarters on the Pruth.

The Turkish army, which passed the winter in Bulgaria, was severely attacked by plague, but no further information about this outbreak is available.

In February 1771, Moldavia and Wallachia suffered very little from plague, although there were occasional outbreaks here and there (for example, in Bucharest) until the year 1773; but these were always of short duration.

The transplantation of this disease into neighbouring countries, especially Russia and its capital, was of particular importance. In consequence of the widespread occurrence of bubonic plague in Moldavia and Wallachia when the war broke out in the spring of 1770, large numbers of fugitives from those parts gathered along the border of Transylvania, where a quarantine establishment was opened at Törzburg (south-west of Kronstadt). In Rukur, a border-village of Wallachia, whither large numbers of people fled daily, a Jewess succumbed at the end of April to bubonic plague, and in the course of the next eight weeks 60 more people died. From there the pestilence spread to neighbouring localities, in which 615 out of 3,000 inhabitants (including 31 outsiders) died. The climax of the plague was in September. It gradually spread throughout the border-towns of Transylvania, but only in occasional instances did it reach the interior of the country; all told, there were 1,024 deaths from the pestilence in Transylvania in the year 1770.

Since all the supplies of the Russian army were conveyed to it on Polish wagons, Polish peasants contracted the disease in the infected countries, and then spread it throughout Poland. Jewish pedlars, who purchased clothes, furs, and war-booty in the Russian camp, likewise helped to spread the disease. In Poland the plague became unusually widespread, particularly in Podolia, Volhynia, and in the eastern part of Galicia; 47 cities and 580 villages, according to Chenot, were attacked, and 275 of the latter were almost completely wiped out. The total loss in these regions is estimated at 250,000. But the disease penetrated no further into Poland, and Warsaw did not suffer at all.

Southern Russia was attacked later than Poland—not until August 1770. Kiev was the first of several cities in which the plague broke out; the disease, which was borne there on infected wares from Podolia, carried away 20,000 people, about one-fifth of the population of the city. Fugitives from Kiev conveyed the pestilence to many cities and villages in Little Russia, while troops returning from Bender helped to spread it in the north. In Nieskin, a city in Ukraine, the plague caused horrible devastation; it broke out there for the second time in the year 1771, and carried away from 8,000 to 10,000 people.

It was generally believed that the severe epidemic of bubonic plague which raged in Moscow in the year 1771 was directly connected with the expedition against the Turks. At that time the city had some 230,000 inhabitants; the streets, full of filth, were narrow, and the houses, most of which were one-story wooden structures, stood close together. According to Hecker, the beginning of the plague is obscure; fugitives from the scene of the war, and wool imported from Poland or Ukraine are both given as the original means of dissemination, but inasmuch as the disease was so widespread in the south, it is probable that it was conveyed to the north in various ways. Schafonsky, writing in Russian, described the plague in an excellent book, of which Hecker made use; the description by a surgeon named Samoilowitz,[[77]] who did good service during the plague, contracted the disease himself, and was roughly treated in a revolt, according to Hecker, lacks scientific merit and is unreliable. In November and December, 1770, there were a few suspected cases in a hospital in the eastern part of the city; Schafonsky diagnosed the disease as bubonic plague, while the medical officer of the city called it typhus fever. By means of strict isolation and other measures this outbreak was soon entirely checked. As early as January and February, however, indubitable cases of plague had occurred, but they were kept secret. The epidemic really began in the Imperial cloth-manufactory, where 3,000 working-men were employed; not until 130 people had died within eight weeks, was this fact made known on March 9, 1771. Since many of the working-men lived in the city and had meanwhile conveyed the disease to their homes, the measures of prevention came too late. The patients were now taken to a convent in Ukresh (near Moscow), while all the rest of the employees were quarantined. But these measures merely helped to spread the disease, since many of the working-men, in order to escape being quarantined, fled and concealed themselves in the city. When it became known that bubonic plague was present in Moscow, the nobility fled to the country. The people themselves refused to listen to any advice; nobody believed in contagion, and in September there was actually a revolt in the city against the measures that had been adopted to check the epidemic. The compulsory confinement in hospitals of infected people and the quarantining of their families led to numerous concealments. In July the pestilence had already become very widespread; many houses in the suburbs were empty, the courts of justice and workshops were closed, and, since nurses and grave-diggers were dying off rapidly, convicts were employed to do their work. In the southern part of the city a convent was converted into a hospital, and at the end of July only one attendant was on hand there to take care of 1,000 patients. The epidemic reached its climax in September, when from 600 to 1,000 persons died every day. By January 1772, the pestilence had disappeared. From the month of April 1771 on, the number of people that contracted the disease and the number that died were officially recorded; the number of deaths (excluding the bodies buried in secret) was:

Months.Total no. deaths.Deaths in Hospitals.

June1,099105

September21,4011,640
October17,5612,626
November5,2351,769

January (1772)330

The number of deaths, which at that time averaged 7,000 per annum in Moscow, thus increased to 58,000 (including some 1,000 secret burials), and at least 52,000 were directly due to the epidemic. About 150 priests were victims of their calling.

During the pestilence there was constant intercourse between Moscow and the surrounding country, since the necessaries of life had to be brought to the city, where clothes and household goods were to be bought very cheaply. Thus most of the villages and cities in the surrounding country were infected. Some of the latter were almost completely depopulated, while the estate-owners found protection by shutting themselves up in their manors. Of the more distant cities Jaroslav-on-the-Volga was very severely attacked, while Borowsk, Kaluga, and Tula suffered somewhat less. St. Petersburg was the only city to prohibit outsiders from entering, and it was consequently spared.
