‘Of course you know why I’m writing’: War letter from 1917 a tale of friendship and sacrifice

Thank you, my friend LTC (Join to see) for sharing the fact that a "long-lost letter found in a flea market in a bunch of papers describes friendship and Friends lost during the Battle of Vimy Ridge." That is wonderful news that this letter has been found.
Nowadays letters are rare but in those days that was the primary means of communication.

Thanks for sharing

Sir,
Thank you for sharing this.
