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,… - Siegfried Sassoon

As regards being dead, however, one of my main consolations has always been that I have the strongest intention of being an extremely active ghost. Let nobody make any mistake about that.

"You smug-faced crowds with kindling eye
Who cheer when soldier lads march by,
Sneak home and pray you'll never know
The hell where youth and laughter go."
"The War Poems"

Have you forgotten yet?...
For the world's events have rumbled on since those gagged days,
Like traffic checked while at the crossing of city-ways:
And the haunted gap in your mind has filled with thoughts that flow
Like clouds in the lit heaven of life; and you're a man reprieved to go,
Taking your peaceful share of Time, with joy to spare.
But the past is just the same — and War's a bloody game...

Have you forgotten yet?...
Look down, and swear by the slain of the War that you'll never forget.

Do you remember the dark months you held the sector at Mametz
The nights you watched and wired and dug and piled sandbags on parapets?
Do you remember the rats; and the stench
Of corpses rotting in front of the front-line trench — And dawn coming, dirty-white, and chill with a hopeless rain?
Do you ever stop and ask, 'Is it all going to happen again?'

Do you remember that hour of din before the attack — And the anger, the blind compassion that seized and shook you then
As you peered at the doomed and haggard faces of your men?
Do you remember the stretcher-cases lurching back
With dying eyes and lolling heads — those ashen-grey
Masks of the lads who once were keen and kind and gay?

Have you forgotten yet?...
Look up, and swear by the green of the spring that you'll never forget.
