"During WWI, Australia shipped about 53,000 horses overseas to serve in the various theatres of that war. Of that number, only one returned to Australia at the end of the war, and it was, of course, a General's favourite mount."

All true, pity Bogle didn't go on to explain the hoops that General had to go through to be allowed to bring his horse back, or the extensive and lengthy quarantine and veterinary checks the horse was subjected to - all expense being paid by that General.

Nice yarn by way of a sleeve note, but my guess is that at some point or other Bogle came across this written much earlier by "Banjo" Paterson about the Second Boer War:

The Last Parade

Andrew Barton Paterson

WITH never a sound of trumpet,
    With never a flag displayed,
The last of the old campaigners
    Lined up for the last parade.
Weary they were and battered,
    Shoeless, and knocked about;
From under their ragged forelocks
    Their hungry eyes looked out.

And they watched as the old commander
    Read out, to the cheering men,
The Nation?s thanks and the orders
    To carry them home again.

And the last of the old campaigners,
    Sinewy, lean, and spare?
He spoke for his hungry comrades:
    ?Have we not done our share?

?Starving and tired and thirsty
    We limped on the blazing plain;
And after a long night?s picket
    You saddled us up again.

?We froze on the wind-swept kopjes
    When the frost lay snowy-white.
Never a halt in the daytime,
    Never a rest at night!

?We knew when the rifles rattled
    From the hillside bare and brown,
And over our weary shoulders
    We felt warm blood run down,

?As we turned for the stretching gallop,
    Crushed to the earth with weight;
But we carried our riders through it?
    Carried them perhaps too late.

?Steel! We were steel to stand it?
    We that have lasted through,
We that are old campaigners
    Pitiful, poor, and few.

?Over the sea you brought us,
    Over the leagues of foam:
Now we have served you fairly
    Will you not take us home?

?Home to the Hunter River,
    To the flats where the lucerne grows;
Home where the Murrumbidgee
    Runs white with the melted snows.

?This is a small thing surely!
    Will not you give command
That the last of the old campaigners
    Go back to their native land??

.    .    .    .    .
They looked at the grim commander,
    But never a sign he made.
?Dismiss!? and the old campaigners
    Moved off from their last parade.

Paterson got the nickname "Banjo" from a none too successful race horse he once bought.
