On 30 January, Canadian Heritage added a file, Military service files for members of the Royal Newfoundland Regiment and bandsmen and the Newfoundland Forestry Corps (1914-1919). It’s an imaged copy of LAC microfilm T-18517. Find it at https://n2t.net/ark:/69429/m20250000769c7j
There are 1375 images for 32 people, none of which are full-text searchable. There’s a list of names on image 7.
Typically the files consist of attestation papers, medical examination forms, conduct sheets, movement cards, pay documents, medical forms, casualty related forms and correspondence to and from the Department of Militia.
While the equivalent CEF files were stripped of what was considered extraneous information, the correspondence in these files offers a clue to what we are missing in the Canadian files. My sampling revealed correspondence regarding applying for and being denied a service gratuity, and returning a uniform.
