The name of arthur

The poet and the troubadour have stolen my name
They poached my true story and gave me false fame
I was a ruler, a warrior, an emperor, a chief
I fought for my people, I fought for my belief
I fought for law and order in fear of chaos reign
To keep out butchery of hell-hounds fateful bane
I fought against savages of iron flesh and bone
To keep them from ravaging my family and home

They've turned me to a gentleman of pallid livery
A puppet for their musings, their whims of chivalry
But I fought no imaginings of courtly smiles and lies
I fought murderous men with evil in their eyes
