The pestilences of the year 1627 were not very widespread, and this applies also to the territory in Saxony and Thuringia which had suffered so severely in the years 1625–6. On the other hand, the countries in the northern part of Germany, particularly Pomerania and Schleswig-Holstein, were severely attacked in those years, owing to the fact that Wallenstein had transferred thither the scene of the war. In the year 1628 Hamburg had taken in a great many foreign fugitives, and the result was that typhus fever soon broke out in the city and carried away many thousands of people. The war brought great misery into North Friesland and the Frisian Islands; the Imperialists and Danes oppressed the people by enforced quartering and extortions of all kinds, and the result was famine and plague, lasting until 1630. In Stade, which Tilly in 1629 had made his head-quarters, both the inhabitants and the garrison suffered terribly from a severe epidemic of dysentery. In the city of Schleswig a plague broke out in September, and again in November, in consequence of the quartering of Imperialist troops; it devastated the entire city, so that 211 houses stood absolutely empty on Christmas Day, 1628. Mecklenburg was revisited in 1629, and on August 13 of that year a plague broke out in Rostock and Teterow. Imperialist soldiers conveyed pestilence to the city of Plau, where they passed the night of November 29; but in 1630 it appeared in a much more severe form there and carried away 600 people. In the year 1630 a plague broke out in Mecklenburg, and in Gustrow one raged from May 7 to the beginning of September. In the years 1628–9 Pomerania was ravaged by the Imperialists, with resulting pestilence and famine. Greifswald suffered for four years from a pestilence which reached its climax in the year 1631. Grimmen, Stargard (3,500 deaths in the years 1627–30), Freienwalde, and other places were also attacked. In Greifenberg, where soldiers had been quartered in large numbers, it raged with unusual fury; three-fourths of the city were devastated, and when the Swedes arrived only 42 houses were uninfected. Kolberg (on the Persante) in six months lost 3,000 inhabitants in consequence of a pestilence. On account of the oppression caused by the war, many citizens fled from Koslin, which, despite the decrease in population, lost 919 inhabitants in the year 1630. In Stolp 800 people died in consequence of a plague.
