When political envoys refused to remove their customary skullcaps in Vlad’s presence, he said “In all fairness, I want to strengthen and recognize your customs” and had the hats nailed to their heads. The forests of Transylvania were growing thick with the impaled, and the unnerved turks dubbed him "Kazikli Voyvoda", the Impaler Prince.
Curious Expeditions has many more examples of his cruelty and iron hand in the story of the real Vlad Tepes. Link
Refer the recently published "Redcoat" (I forget the names of the author and publisher).
Oh, and Tempscire wins the Interweb for finding the post!
there was this horrible pyramid of a spike that he would impale people by.
forcing the spike to enter their body through a private orifice until it reached their brain, at which point they would no longer feel the pain sustained and die immediately.
but that time from entry until death... mustve been so unimaginably painful.
