Deluded

A conpiracy they said had begun.
In the twighlight
Tramping feet are heard.
Spears and lighted torches
Are apparent in the moon so white.
In the castle's garden
The enemy will indict
A rather innocent mind.
In one blow of the horn,
Arrows fly into the night.
Betrayal, deception, disgrace
Escape into the waking morn;
One shouts "Mio Cid!",
And it ends the chase.
