[Plutarch]

This is another version of Khan's quote, with words that seem more Khan-appropriate. Source is Keegan's book, which is well worth reading:

In "A History of Warfare," John Keegan describes the curious mentality and values of a warrior. Genghis Khan, for example, "questioning his Mongol comrades-in-arms about life's sweetest pleasure and being told it lay in falconry, replied:

'You are mistaken. Man's greatest good fortune is to chase and defeat his enemy, seize his total possessions, leave his married women weeping and wailing, ride his gelding [and] use the bodies of his women as a nightshirt and support.'"

The Keegan one sounds much better...I like him a great deal. I still think the story is somewhat apocryphal, but I'll buy Keegan's version. Thanks!
