Typhus fever also appeared in the western scene of the war, where the Imperialist and French troops were fighting against the Prussians. When the united Imperialist and French armies besieged Eisenach for two weeks, the disease broke out in both military hospitals in the city and afterwards spread among the inhabitants, causing many deaths.

(b) Eastern Europe

During the numerous wars that were waged in eastern Europe in the course of the seventeenth and eighteenth centuries, epidemic diseases frequently made their appearance. After the siege of Vienna (1683), typhus fever broke out in various parts of Hungary, particularly in Pressburg, where many soldiers were congregated. The disease spread from the soldiers to the civilians, and the pestilence lasted from November 1683 to the spring of 1684. After the return of the Prussian troops from Hungary, typhus fever broke out in many parts of Germany; for example, in Minden.[[71]]

At the beginning of the eighteenth century bubonic plague broke out in Constantinople and spread from there to the Lower Danube countries and to Russia, particularly to Ukraine. According to Hecker,[[72]] this dissemination was greatly furthered by the adventurous campaign of Charles XII of Sweden, so that the epidemic included all eastern Europe and gradually embraced north-western Germany and Sweden. Fleeing Swedish and Polish soldiers, after the battle of Pultowa (July 8, 1707), conveyed the disease to Silesia. Danzig was severely attacked in that year, and a few cases occurred there in the year 1708; but in the following year a very severe pestilence broke out, reached its climax in September, and between January 5 and December 7, 1709, carried away 32,599 persons. From Danzig the plague spread to Courland, Livonia, Pomerania, Denmark, and Sweden. In Copenhagen 20,822 persons died in the year 1710, in Stockholm 40,000, in Karlskrona 16,000.

In the years 1716–18, when Austria and Turkey once more came to blows over the Turkish occupation of Morea, which belonged to the Venetians, bubonic plague broke out in Constantinople and also among the Turks who were shut up in Belgrade. The Austrian army, which was encamped outside of Belgrade, was apparently not attacked by that disease, although some 4,000 men succumbed to intermitting fever, head-disease, and dysentery.[[73]]

During the war waged by Russia and Austria against Turkey (1736–9), bubonic plague appeared along the Lower Danube. ‘It broke out there,’ says Häser,[[74]] ‘first during the war waged by Austria and Russia against Turkey, and the result was that the war was terminated unexpectedly, and in a manner unfavourable to the Christian arms. At the time of its appearance in Ukraine (July 1738) the disease was conveyed by Austrian troops to Temesvar; from there it gradually spread over all Hungary, mostly along the banks of the Theiss to the boundaries of Carniola, Moravia, and Austria, and also along the Carpathian Mountains to Poland and Bukowina. The devastation caused by the pestilence continued for seven years, and the measures adopted by the authorities proved of little or no avail.

The severe epidemic of bubonic plague during the Russo-Turkish War of 1769–72 has been carefully investigated by Hecker.[[75]] The Turkish army, in consequence of inferior nourishment, was badly infected with intermittent fever, dysentery, and typhus fever when it set out from Constantinople in March 1769. When the Russian troops advanced, the Turks retreated after an engagement near Galatz. Since the disease had been conveyed on ships from Constantinople to Galatz, where many Russians succumbed to it, the city was evacuated. On the way to Jassy every trace of the pestilence disappeared, and in Jassy the soldiers were quartered in the houses of the citizens. Since patients suffering from contagious diseases had not been isolated in the military hospitals there, in the middle of January typhus fever broke out in them, accompanied by glandular swellings in the groin. Four weeks later a Jew and his two children were taken sick in the city and died, the Jew having bought a fur coat in the hospital. Since the Russian commander-in-chief did not hold the disease to be bubonic plague and did nothing to prevent it from spreading, in March 1770 it spread far and wide in Moldavia and Wallachia. Not until the end of April was the presence of bubonic plague officially admitted; and then the well-qualified physician Orraeus was commissioned to make an investigation.

From Jassy the disease was conveyed to Botoshany, which also lies in northern Moldavia, and there it soon developed into a severe epidemic and carried away more than 800 out the town’s 2,500 inhabitants; the rest fled to Carpathia. ‘The patients,’ says Hecker,[[76]] ‘lay in tents, and without care or medical help awaited an almost certain death. The city itself afforded a sight of complete disorder; the houses were deserted and stood with open windows and doors, the air was poisoned with the odour of accumulated refuse, and the general devastation bore silent witness to the most extreme misery. In addition to that, there were multitudes of savage, ravenous dogs, which dug up the dead and menaced the sick.’

Conditions were just as bad in Jassy when Orraeus arrived there on May 10; of the inhabitants and of the Russian garrison more than half had died, while many streets were entirely depopulated. Since the persons infected with the disease were placed out in a near-by forest, where they were left without care, many patients were concealed inside the houses and their bodies afterwards secretly buried in gardens and cellars. There was no medical help, since both of the Greek physicians had fled from the city. On May 20 the Russian troops, at the instigation of Orraeus, withdrew from Jassy; a convent was converted into a hospital, and soon after that the pestilence began to subside. By June 22 it had disappeared.

In Wallachia the disease broke out somewhat later than in Moldavia, and with considerably less severity. In Bucharest it lasted until May.
