The Seven Years’ War was attended by several epidemics of typhus fever. Notwithstanding the long duration of the war, they did not become very widespread, inasmuch as the armies were comparatively small, and as the scene of the fighting, in accordance with the military tactics of Frederick the Great, who opposed first one and then another Power, kept changing, and thus caused no one region to suffer for any great length of time. A severe epidemic of typhus fever broke out in Silesia in the year 1758; it raged in both the Austrian and Prussian armies, and spread to many places, for example, to Breslau, Schweidnitz, and Landshut, where the civil inhabitants also became infected. In Breslau, according to Grätzer,[66] the number of deaths among the evangelical population was: 1756 1,375 1757 1,554 1758 4,088 1759 1,697 1760 1,590 1761 1,724 1762 2,373 1763 1,808 According to Süssmilch,[67] the number of deaths among the Catholics in the year 1758 was 5,135; thus the total number of deaths in the entire civil population was 9,223. In addition, the following military persons were buried: 5,470 Prussian soldiers, 2,153 Austrian soldiers, 18 Swedish soldiers; also 755 wives and children of soldiers, and 953 paupers and outsiders. The total number of interments in Breslau in that year was 18,572. The great mortality lasted from January to June; of 9,349 military persons buried, there died in: January 1,346 February 1,709 March 1,246 April 940 May 1,287 June 818 July 457 August 578 September 383 October 201 November 164 December 220 In the year 1757, in which there was a high mortality in a large part of North Germany that was unaffected by the war, there was an unusually large number of deaths in Dresden; in the year 1760, when the city was beleaguered by Frederick the Great, a ‘virulent epidemic fever’ broke out and again caused a great increase in the death-rate. The number of deaths in Dresden (excluding the still-births) was:[68] 1756 2,432 1757 4,454 1758 2,603 1759 2,631 1760 3,514 1761 2,127 1762 2,008 1763 1,975
