1939 Civil Defence Leaflet: “Some Things You Should Know if War Should Come”

This 1939 Civil Defence leaflet, titled "Some Things You Should Know if War Should Come," was distributed by the Lord Privy Seal’s Office in July 1939, just weeks before the outbreak of World War II. It served as the first in a series of public information pamphlets designed to prepare British civilians for air raids, blackout regulations, and the potential use of gas. The leaflet's stark instruction, "Read this and keep it carefully. You may need it," underscores the government's effort to balance reassurance with the grim reality of impending conflict. Millions of these leaflets were delivered across Britain, forming a crucial part of an unprecedented civil preparedness campaign and serving as historical artifacts of the anxious period leading up to the war.
