what does it mean when general says Where there are pistol shots, there are men. Where there are men, there is food," in the story most...

This quote is early in the story.  Rainsford has fallen
off of the boat he was on and has been lucky enough to have survived the swim to shore.
The pistol shots he heard when he was in the water led him to the shore.  However when
he arrive, he collapsed from exhaustion.  He awoke the next afternoon, refreshed, but
very hungry. He needed to find some food.  Remember that he was a hunter, so he
logically thought .... where there are pistol shots, there are men --- because human
beings are the only ones who could use pistols.  Where there are men, there is food ---
because it is a necessity for life.  He did not know what he would find, but he was
looking for food first, for survival.
