Ultramarines, Ultramarines
The greatest of the legions the Imperium has seen
Ultramarines, crush all heresy
For the throne of his majesty
The Ultramarines

We march for Macragge
On every crusade
Following the codex every day

We serve beneath the flag
We make the traitors beg
A debt in blood the Sons of Horus pay

Our brave Avenging Son will lead us all from here
And all the 13th legion knows no fear

Ultramarines, Ultramarines
The greatest of the legions the Imperium has seen
Ultramarines, crush all heresy
For the throne of his majesty
The Ultramarines

We die for the throne
At Calth long ago
Remembering our brothers every day

They tried to put us down
A coup for the crown
A debt in blood the Sons of Horus pay

Our brave Avenging Son will lead us all from here
And all the 13th legion knows no fear

Ultramarines, Ultramarines
The greatest of the legions the Imperium has seen
Ultramarines, crush all heresy
For the throne of his majesty
The Ultramarines

Ultramarines, Ultramarines
The greatest of the legions the Imperium has seen
Ultramarines, crush all heresy
For the throne of his majesty
The Ultramarines
