In the Governmental District of Minden only the city and vicinity of Minden were severely attacked; before the war began they were free from small-pox. On September 10 the first prisoners arrived, and among them cases of small-pox had already been observed in the first part of that month; in the course of the next eight days more cases were reported, and of a total number of 5,071 prisoners 98 contracted the disease and 13 succumbed to it. In the garrison, which numbered 5,071 men, one case was reported in October, four in December, and fifty-two in the following months; only two cases terminated fatally. The first case among the civil inhabitants was reported on November 5; the victim was a laundress who had done washing for the prisoners. This constituted the beginning of an epidemic in which 651 persons contracted the disease and 114 succumbed to it; the population of the city was 16,862. The epidemic spread to the surrounding localities, presumably because the woollen blankets which the patients had used were sold there. Throughout the entire district of Minden 391 persons (51·0 per 10,000 inhabitants) succumbed to small-pox in the year 1871, whereas in the following year only 34 deaths were reported, all told. In the Governmental District of Arnsberg the districts of Dortmund and Bochum, which belonged to the Rhenish-Westphalian coal region, and were even at that time densely populated, were severely attacked by small-pox; the districts of Hamm and Hagen, which bordered on the latter, were likewise very hard hit. The following table indicates the number of persons per 10,000 inhabitants that succumbed to small-pox in the districts mentioned: 1871. 1872.
