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!
