WWI Cover And Interesting Contents

There's really not much going on with this cover but like many covers especially covers from the WWI period it's the letter and contents that make things interesting.
Here's a letter showing the harsh reality of the heartbreak, sorrow and sacrifice our brave soldiers and their family's endured during WWI.
I included a picture of Corporal Bertrand and a photo of his gravesite and was quite surprised to see he was buried along with another soldier killed on the same day.
I had heard of this happening before but only in letters and had thought they only meant in the same graveyard not actually the same grave.

As I said there's little going on with the cover and stamp but I just wanted to share it, I hope someone will enjoy.

Cheers, Bill

Wow!

Impactive letter. Sad.

Thanks for sharing.
The cover is addressed to Mrs. John Simpson but the letter is to Mrs. Percy Bertrand. Is there some indication of their connection?

Is it possible that the letter and envelope shown do not go together?

The letter is datelined Aug 31, 1918. The receiving mark on the reverse of the cover looks like June 27, 1920? maybe (not familiar with structure of Canadian dates), and the PO name in that mark is different from the address. If there was a group of letters, is it possible that some envelopes and contents got mixed?

I had this happen to me once. During a six month period, I bought two registered covers from Texas to Switzerland (1880s) from the same dealer in Europe. Both covers had contents, but neither letter belonged to the envelope in which it was purchased. However, by coincidence, one of the letters belonged to the other envelope. Never found the second letter although I asked the dealer if he had any other items from the correspondence.

I won't get into the complicated relationship of all the people here but through a number of other letters and research I've been able to ascertain that they all were originally from the same general area and Mrs. Simpson knew the Tanners.
Sgt. Bertrand, Tanner and Mrs. Simpsons two sons Frank and Russel Simpson were all in the 93rd Battalion.
They trained here together, sailed to England together on the same ship and were sent to front lines to the 1st Division all at the same time.
There is a section on the first page I omitted because I didn't really want to get to deeply involved in the story.
Trust me they're at the very least well acquainted.
It also should be noted that Tanner is made sergeant on August 29, 1918 the day after Sgt. Bertrands death.
it would not surprise me greatly if it was discovered that his promotion was due to Bertrand's death.
