Thanks to the well-vaccinated condition of the German troops, the army suffered comparatively little from small-pox. In the field army 4,385 men (61·3 per 1,000) contracted the disease, and 278 of them (3·5 per cent of those who contracted it) died. Including the officers, physicians, and officials, the number taken sick was 4,991 and the number that died was 297. The number of men in the individual army corps that contracted the disease varied greatly according to the nature and place of their activity; particularly hard hit were the army divisions in the south-western and northern scenes of the war, where the military operations were carried on in fearfully cold weather, and where it was impossible to quarter the infected soldiers in isolated places by themselves. The French army was attacked much more severely by small-pox, although there are no accurate reports available regarding the prevalence of the disease. According to a report found in the _Vienna Medical Weekly_,[262] the total number of French soldiers that succumbed to small-pox was 23,469[263]; but the accuracy of this number, to be sure, is questionable, since, assuming that there was a very high mortality, it would mean that some 120,000 troops contracted the disease. At all events, the French army, taken as a whole, was badly infected with small-pox, and it was inevitable that among the French prisoners brought to Germany there should be numerous small-pox patients, some in the incubation stage, and some in the convalescent stage of the disease, and that they should infect other people there.
