Mecklenburg suffered terribly in the years 1637–8 from the quartering of Swedish troops there. Thousands succumbed in a short time to dysentery and bubonic plague, especially in the months of August and September 1638. Güstrow, in the year 1637, is said to have lost 2,000 persons (most of them doubtless fugitive country-people). Sternberg, the population of which was completely wiped out by the pestilence, stood empty for half a year. In New Brandenburg, where many country-people had taken refuge, 8,000 people died in the year 1638, according to the church register. Bützow had 261 deaths. IV. THE WAR YEARS (1641–8) After the death of Bernhard von Weimar and of Banner, all centralized warfare in Germany ceased, and there began an endless series of futile marches across the country. The great depopulation of Germany, the difficulty of properly nourishing the few that had survived, and the wide prevalence of camp-fever, made it impossible to carry out any more large enterprises. Severe pestilences scarcely ever occurred, for the simple reason that there were so few people to contract and spread diseases. Typhus fever had become epidemic everywhere. ‘In Germany,’ says Schnurrer,[45] ‘where fighting had been going on for twenty-two years, and where soldier-life had almost supplanted civil and rural life, a certain war-plague revealed itself in places where there were soldiers, and where the war had left its vestiges. This war-plague was characterized by a mucous fever, began with a chill, accompanied by coughing, diarrhoea, and, in the case of women, by increased and irregular menstruation; at the same time the tongue became dry, headache and insomnia ensued, and at the crisis either the brain or the throat became inflamed, or else petechiae or purpura (then for the first time observed in Lower Saxony) broke out. Moreover, this war-plague, if it appeared to have passed a crisis on the fourteenth or twenty-first day, manifested a remarkable tendency to relapse. It was quite as infectious as bubonic plague, and was called by several names—Hungarian fever, head-disease, and soldiers’ disease.’ We distinctly see in this description a mixture of various diseases (especially typhoid fever, typhus fever, and others). Schnurrer’s authority was Lotichius, a Frankfurt physician. The continuation of the war was disastrous to Austria, for the reason that the Swedish general, Torstensen, pressed on to Moravia and Lower Austria. As early as the year 1642 he had undertaken an expedition through Silesia to Moravia and Bohemia; in the year 1644 he advanced again, defeated the Imperialists at Jankau in Bohemia in the spring of the year 1645, and besieged (unsuccessfully) both Vienna and Brünn. In the year 1645 he was hard pressed by the Austrians and compelled to evacuate Moravia and Bohemia. Torstensen’s campaigns resulted in the outbreak of severe pestilences throughout all Austria.
