Special death

A terrible mistake was made
The weight would break the backs
Of ten strong horses, tried to save
The castle in the fray

If you knew that I could take the pain
Inflicted at the battle
With faithful arrows, you
Might get back in the saddle

But it's a special death you saved
For me, the brown-eyed daughter
Once you made it hotter
The thankless, holy praise
Is left alone
Why bother
To cast a stone in water?
