I wish I’d known about this before I started blogging about CEF burials at Beechwood Cemetery.
At the Library and Archives Canada website follow links Military Heritage > First World War> Sources Relating to Units of the Canadian Expeditionary Force. Scroll down to find a list of 31 pdf files, typically less than 200 KB.
There’s one very large file, Infantry Battalions (PDF 3,020 KB). It has a numerically ordered list of the CEF battalions, 1 to 260 plus two named battalions.
For each there’s a boxed section Background Information, the example is for the 28th Battalion in which my great uncle served. Then there’s an extensive list of sources from RG9 and RG24 at LAC. None have links.
Knowing about this obscure resource earlier would have simplified writing the CEF Beechwood posts.
