But the 1939 register did not contain a full comprehensive list of the entire population.
It did not contain details of merchant navy personnel, nor did it contain the names of all service personnel, did it?
The 1939 Register was designed to capture the whereabouts of the
civilian population on a specific date. It doesn't include British Army barracks, Royal Navy stations,Royal Air Force stations
or members of the armed forces billeted in homes, including their own homes. Obviously as they were accounted for elsewhere and I think already had identity cards. It does include those who were at home on leave.
