What an elegy this is. The fact that you knew him so well is a testament to how infectious of a life he had.
"how should he die
When cruel old campaigners win safe through?
But death replied: “I choose him.” So he went,
And there was silence in the summer night;
Silence and safety; and the veils of sleep.
Then, far away, the thudding of the guns."
-Siegfried Sassoon, The Death Bed
