Add my dittos to all the previous Bogle recommendations. And, somebody finally mentioned "Lorena" a song so devastating that its singing was banned in the camps, 'cause it made everyone want to go AWOL.

Back to Bogle, "The Band Played Waltzing Matilda" (my all-time favorite) and "No Man's Land" are part of his WWI song trilogy. The third, almost never heard, is:

For King And Country — Eric Bogle

CHORUS (Each stanza)
For King and for Country,
We fought and we died.
In the first flush of the dawn
In the fields of Somme.

First to die was our Captain,
He was shot through the lung.
He lay in the mud
And he choked in his blood.

And ten minutes later,
On these green fields of France,
The grass has turned red,
And thousands were dead.

And all through that morning,
The slaughter went on.
We screamed and we cried,
And cursed God as we died.

And when it was over,
And the killing was done,
A generation had gone.
A generation had gone!
