In calm bureaucratic language -- loaded with code words to render the book meaningless to those not in the know -- the document describes how as the crisis worsened, civil servants would introduce censorship, evacuate all but the sickest patients from hospitals and eventually be sent to one of 12 underground bunkers scattered around the country.
Britain was to be governed from these bunkers after a nuclear attack, with officials exercising powers of martial law over the remaining population. [More]
And it sounds like they had things planned down to a remarkable level of detail:
Nuclear reactors could provide power almost indefinitely. Greenhouses could maintain plantlife. Animals could be bred and slaughtered. A quick survey would have to be made of all the available mine sites in the country. But I would guess... that ah, dwelling space for several hundred thousands of our people could easily be provided...And a computer could be set and programmed to accept factors from youth, health, sexual fertility, intelligence, and a cross section of necessary skills. Of course it would be absolutely vital that our top government and military men be included to foster and impart the required principles of leadership and tradition. Naturally, they would breed prodigiously, eh? There would be much time, and little to do. But ah with the proper breeding techniques and a ratio of say, ten females to each male, I would guess that they could then work their way back to the present gross national product within say, twenty years.It would not be difficult, mein Fuhrer! Especially with the population disarmed and dependent.
We must not allow a wheelie-bin gap!
