Zachary resisted the urge to flinch, the warrior was far more sturdy than he anticipated.  He put his stock in the Lord to see him through, after all was he not fighting for a righteous cause to prevent the rape of his daughter?  The warrior didn't seem to be dodging or avoiding his blows, which mean that Zachary could invest less energy in running around the warrior.  Instead he chose to hit the warrior with blows infused with the desperate energy of a fanatic.
