[ WP ] What happend to the cowboy after he rode off into the sunset ?

After defeating a camp of native savages and telling the love of his life that he would one day return, the cowboy ( let's call him Bill ) rode off into the sunset. 
 
 The fiery sun beamed down on our hero's ear-to-ear grin. For the first time in his life, he felt fulfilled. He was a hero. A hundred years from now men would be writing books about his glorious adventures. He was confident about this. 
 
 But a thought interrupted these fantasies. An unwelcome thought. And his grin turned to a grimace. What if he was n't the hero? 
 
 Of course he was. He had helped clear out a camp of savages to make room for more civilized folk. Bill had taken that land for God's people, and God thanked him. These reassurances brought that grin back into good-ole-Bill's face. 
 
 
 And the sack of Indian heads that thumped around on the horse's back would fetch good money from the government back in California.
