This 16-page document has the heading:
Official Lists of:—
Volunteer Defence Forces—Prisoners of War
Volunteer Defence Forces—Casualties
Compiled from information received by the Colonial Office, London, from the Japanese Authorities, Tokio, in telegraphic despatches between the 18th August and 16th December, 1942, and transmitted to the Finance Liaison Officer, Hong Kong Government, through the High Commissioner for the United Kingdom, Canberra
It is followed by lists of names, collected into different groups. I'll add the groups over time, and add links to them below.
Many thanks to Martin Heyes for forwarding scans of this document to me. They were passed to him by the family of William (Bill) Stirton McHardy.
