The poem describes a soldier attempting to get into heaven, but worried that he's not done enough good with his life - only to be told by St. Peter (I think), :
"You've seen your share of hell."
Think the poem was perhaps used in the film Saving Private Ryan or at the start of the PS2 game Medal of Honour.
W N Holland, the son of another Desert Rat wrote a poem in tribute to the "Rats of Tobruk"
Regimental standards dip,
Once more we say farewell.
One more comrade, who in honour fought,
With God has gone to dwell.
Remember he, like thousands more,
His youth did gladly give,
That those who would come after him,
In peace and truth might live.
His children, perhaps not old enough to know
The hell he saw.
Pray we all, and silently,
That nevermore upon this scale,
Be loosed the dogs of war.
To members of his family,
Who bravely check their tears,
As husband, father, provider, friend,
Loyal all these years - We, your comrades,
In our hearts, Bid you our farewell,
Your watch is over, duty done,
Sleep long in God's sweet peace,
You've seen your share of hell.
An Internet search of ‘share of hell’ plus ‘Peter’ brings up numerous anonymous versions applying this joke (“You’ve had your share of hell”) to different professions and occupations. For instance:
A Para stood at the gates of heaven
He looked both weary and old
He timidly asked St Peter
For admission to the fold
What right have you the great saint cried
To gain admission here
I have been with the third battalion said he
For many a weary year
The gates were then thrown open wide
St Peter tolled the bell
Come in my son you are welcome here
You have had your share of HELL
There is also a poem adopted by the US Marine Corps, which includes the verse:
And when he gets to Heaven,
St. Peter he will tell,
"One more Marine reporting sir,
I've served my time in Hell."
"I died in Hell (they called it Passchendaele)..."
