Why did sir john Anderson arrange for so many to be built?

Sir John Anderson, as the British Home Secretary during World War II, arranged for the construction of numerous air raid shelters to protect civilians from bombings during the Blitz. His initiative aimed to ensure public safety and maintain morale in the face of aerial attacks on cities. By providing accessible shelters, he sought to minimize casualties and reassure the population that measures were in place to safeguard their lives. This approach reflected a broader strategy to bolster resilience and unity among the British people during a time of crisis.
