Текст песни Light of Aidan - Lament

This song is supposedly written in Celtic, here is the English translation:

And my army of brothers went over the hilltops,
drenched in blood we may be ...
but fighting is all left to me ...
Together with my army of brothers ...
down we fall ...
darkness in all ...
through hell!

My translation into Russian:

And the army of my brothers marched through the hills,
And maybe blood is up to our knees ...
Only the battle is left for me
Together with my army of brothers
Falling down
Only darkness is everywhere
Through Hell!
