A file containing intelligence reports relating to civil defence prepared twice a day for the Home Security War Room, primarily recounting the times, locations, and impacts of individual enemy attacks on the United Kingdom. Topics covered in the reports include sightings of enemy aircraft; false air-raid warnings triggered by causes such as electrical faults and hoax calls; reports of security issues such as explosives being located in public places and activity by the I.R.A.; instances of sea mines washing ashore; shipwrecks in British waters and survivors either rescued or washed ashore; and reports of people trespassing in sensitive locations. Other topics covered include industrial action and strikes; industrial accidents such as factory fires; problems with Britain's infrastructure, such as rail collisions and the effect of bad weather on roads and railways; and enemy air raids, with details of the level of damage caused and the number of bombs dropped.
