I've never seen the correct chords for this fantastic song anywhere, so I decided to 
figure it out myself.

Standard tuning, no capo.
B - x24442
Em - 022000
G#m - 466444
G - 320003 / 355433
C - x32010 / 81010988 (this one fits the song more closely)
D# - x68886

Intro

B Em B Em

Verse:

        G#m           G           B
In this dark night we stand or we fall
       G#m           G          B
We are kings now, or nothing at all
           G#m     G
Check your a-rmor; light up your torch
          G#m                          Em
Touch the flame to the sail before you head for the shore.

Chorus:

            B
And we will burn the fleet,
       Em
We can ne-ver go home;
      B               Em
So to vict'ry or under-ground;
B                        Em
Burn the fleet, we'll be he-roes or ghosts
       B               G
But we won't be turned a-round.

Verse 2:

          G#m           G             B
Yeah, the old flag will burn with the sail
      G#m           G         B
And a new one won't fly if we fail.
        G#m      G
But the fire con-tinues to rise,
       G#m                     Em
And it shows not a hint of any fear in our eyes.

Chorus:

            B
And we will burn the fleet,
       Em
We can ne-ver go home;
      B               Em
So to vict'ry or under-ground;
B                        Em
Burn the fleet, we'll be he-roes or ghosts
       B               G
But we won't be turned a-round.
