I got Porlocked

Go tell the Spartans:
Where the path of the fury takes us,
Though foundation and empire shatter
And the stars asunder wrend,
Til the mountains of mourning crumble
And a fire is upon the deep,
Til the shards of honor are gathered
And the forever war is won,
The guns of Avalon go silent
And the long patrol come home,
Ours is the fury--a high crusade-- 
To bring in the steel with our brothers in arms.
Soldier, ask not, lest darkness fall,
Of unfinished tales or a dry, quiet war.
For us the living, sum the cold equations,
Counting the cost of the human edge.
If the price of the stars 
Be the broken sword,
If the price of the stars
Be the rebel worlds,
If the price of the stars
Be the demon breed,
By God, we have paid it dear!
