Since not everything necessary to provide protection could be paid for, states opted for particular strategies to try to minimize the potential social damage. Evacuation was one way of ensuring the possible survival of large fractions of the urban community. In France, where there was profound concern throughout the interwar years about the problems for security posed by a sharply declining rate of population growth, the social body was to be preserved by moving women and children out of the city in an organized way as soon as war began, since they were the biological investment for the future. Extensive provision was made for evacuation in the late 1930s, and the delay in sending an ultimatum to Berlin following the German attack on Poland was excused by the need to transport the vulnerable population out of Paris in anticipation of a sudden, annihilating air attack.64
In Germany, where pro-natalist priorities were equally evident, the Hitler government opted to avoid mass evacuations, first by encouraging local communities to establish ‘self-protection’ through rigorous civil defence training and the creation of private cellar and basement shelters, and second by reliance on an extensive military anti-air defence of guns, searchlights and radar. By making the population stay put, it was hoped that Germany’s war economy would suffer less disruption; but it also met the ideological requirement to demonstrate family and community solidarity in the face of the aerial threat.65 In Britain, limited evacuation was organized in the late 1930s, but greater emphasis was put on preparations for gas warfare, since fear of gas bombing remained at the forefront of British interwar anxieties about the bombing war. Gas masks were produced for the entire population, and decontamination squads organized earlier and trained more thoroughly than other civil defenders. In Germany masks were issued only to the population most likely to be under threat, in France they were issued late and in insufficient numbers, while in Italy masks had to be bought at considerable expense, and were poorly distributed. In the Soviet Union, where the gas mask was a symbol of a nationwide anti-air organization, Osoviakhim, supplies never exceeded more than 10 per cent of the population.66Civil defence regimes everywhere in the 1930s depended on some level of popular participation. One of the implications of total war waged by bomber aircraft was the need for home populations to recognize that they would become, willy-nilly, a home army combating the effects of air raids. Levels of participation, not all of it voluntary, varied from state to state. In Germany and the Soviet Union, mass organizations were created – 13 million in the German Air Defence League (
