What may be the saddest war song ever

Today my husband played the 3 cd set of "The Dubliners; Ireland's No. 1 Folk Group" in exercise class. Irish songs are minor key and very sad. Our "cool down" song must be the world's saddest war song. It's about the Irish-Australian soldiers who returned from WWI, a war when losing 7-8,000 men in one battle over several days wasn't unusual. And even so, more American soldiers died of the flu than from the war. Here's just part of it:

They collected the wounded, the crippled, the maimed
And they shipped us back home to Australia
The armless, the legless, the blind and the insane
Those proud wounded heroes of Suvla
And when the ship pulled into Circular Quay
I looked at the place where me legs used to be
And thank Christ there was no one there waiting for me
To grieve and to mourn and to pity

And the Band played Waltzing Matilda
When they carried us down the gangway
Oh nobody cheered, they just stood there and stared
Then they turned all their faces away

Now every April I sit on my porch
And I watch the parade pass before me
I see my old comrades, how proudly they march
Renewing their dreams of past glories
I see the old men all tired, stiff and worn
Those weary old heroes of a forgotten war
And the young people ask "What are they marching for?"
And I ask myself the same question.
