The job of civil servants was to keep British government ministers informed.
This report is a typical example of a report from a civil servant looking
back over an important event and analysing its key features.
As a general rule, ministers wanted to hear the views of the civil servant
rather than get the civil servants to sum up all the possible views. This
document shows some evidence of this approach.
It was published in 1950, around a year after the Blockade was over.
