I have discovered that David's family letters are available through the Letters & Images Project located at Vancouver Island University's history department (www.canadianletters.ca). Because we know what is coming there is an increased poignancy to Dave's last letter to Lettie:
France
April 5th
Dear Lettie

Dave
Here is the final letter in the series:
The heavy loss which you and the Nation have sustained would indeed be dressing were it not redeemed by the knowledge that the brave comrade for whom we mourn performed his duties fearlessly and well as become a good soldier, and gave his life for the great cause of Human Liberty and the defense of the Empire.
July 6, 1917
Personal
Dear Mrs. McLean,
I desire to express to you my sincere sympathy in the recent decease of your husband, No. 799658 Pte. David McLean.
Who in sacrificing his life at the front in action with the enemy, has rendered the highest services of a worthy citizen.

Again extending to you in your bereavement my condolence and heartfelt sympathy.
I am
Yours faithfully,
E.A. Kemp
Minister of Militia and Defence for Canada
I have attached two photos of David, his friend Thomas Grant, and some of their mates taken in France shortly before their deaths. In the top photo David is sitting in the front row left, his friend Tom is standing immediately behind. In the second photo Dave is sitting far right. Tom Grant is in the row behind immediately to Dave's right.
