The pestilence broke out in Leipzig in October 1630, and carried away 301 persons; it was borne there presumably by two foreign orange-pedlars. In October of the following year it broke out again, when the Imperialists, after besieging the city for several weeks, on September 13 had finally captured it. The number of deaths in the entire year was 1,754. In the year 1632 Leipzig was once more the scene of grave warlike events, and was compelled to live through a second siege by Wallenstein; the plague began in June, became very widespread in August, and from then till October caused a great many deaths, the total number for the year amounting to 1,390. In August 1633, Leipzig was again besieged, and this likewise caused the outbreak of a plague which lasted until December and carried away 761 persons; in 1634 it was apparently over, for of 306 deaths that are recorded for that year, only 24 were attributable to the plague. In the years 1636–7, however, it reappeared with great severity throughout the entire city. The country surrounding Leipzig suffered a great deal in the year 1633, which was the worst plague-year that Saxony passed through. In the year 1632 Altenburg was occupied by the Swedes, who were infected with some pestilential disease, the germ of which they left behind them when they withdrew on January 13, 1633. The disease spread rapidly, acquired a virulent character, and carried away 2,104 persons, among them many foreign refugees. Grimma and Borna were severely attacked in 1633, while Wurzen suffered less severely.
