To drive our enemies before us, slaughter their warriors and hear the lamentations of their women.
In case you're interested, the full quote from Genghis Khan from my War and Doctrine Army manual [P612, the P is not page, it's the number of the manual] is as follows:
Annihilation: A man's greatest pleasure is to defeat his enemies, to drive them before him, to take from them that which they possessed, to see those whom they cherished in tears, to ride their horses, to hold their wives and daughters in his arms. I forbid you to show mercy to my enemies without an express order from me. Genghis Khan
