Borogravian National Anthem

The Borogravian National Anthem is probably one of the most warlike anthems going:

Awake, ye sons of the Motherland!

Taste no more the wine of the sour apples

Woodsmen, grasp your choppers!

Farmers, slaughter with the tool formerly used for lifting beets the foe!

Frustrate the endless wiles of our enemies

We into the darkness march singing

Against the whole world in arms coming

But see the golden light upon the mountain tops!

The new day is a great big fish!

As Samuel Vimes remarked to Ankh-Morpork's diplomatic envoy any national anthem that starts with Awake! is going to cause trouble.

The last line - whilst problematic to speakers of Morporkian - is a reference to something good about to happen.

Annotation

A real world equivalent could be the Anthem of Romania, an eastern Balkan country with a past not unlike Borogravia's, which also starts with Awake! and is quite warlike:

Awake, Romanian, shake off the deadly slumber

The scourge of inauspicious barbarian tyrannies

And now or never to a bright horizon clamber

That shall to shame put all your enemies.

It's now or never that we prove to the world

That in these veins still flows Roman blood

And in our hearts for ever we glorify a name

Triumphant in battles, the name of gallant Trajan.

Behold, imperial shadows, Michael, Stephen, Corvinus

At the Romanian nation, your mighty progeny

With arms like steel and hearts of fire impetuous

"Life in liberty, or death", that's what we all decree.

Priests, raise the cross, as this army is Christian

Give it liberty and it's sanctified scope

We'd rather die in glorious battle

Than live again enslaved on our ancestral land.
