A soldiers lament

I found this in one of the books in my library dated 1917 the book is a 1st Ed 1917 the poem goes;
"All's well, All's well!
But who can tell?
In this pell-mell
Midst shot & shell
Which seems like hell
All's well.

All's well! All's well!
We too can tell
For foo is nigh
He hears the sigh
Then all is well!
All is well!".

Author Ross Edward he dedicated it to a Mr Buchanan dated as seen 1917 it was written by a person who may have given it all.
Who knows what the relationship was maybe on leave from the front to England which did not happen often in WWI.

Infact in one of my books I have the author spent 3 years at war before being rotated for leave to England for a furlough he was a private and rose to be a Lewis gunner.
Imagine suffering 3 years of hell then 10 days leave in his book he says you were never away from the noise or the death when in the rear due to long range shells.
When he came back from leave the cold hand of war had taken some of his closest friends of whom he thought the world as they shared everything like soldiers do.
Though being an Aussie he had the usual stories of farm stays with chickens and eggs disappearing overnight somehow?????
