The bullets were dancing all around a certain soldier as he dove into the nearest foxhole.  Finding that the hole wasn't very deep, he took his helmet and started digging for all he was worth to give himself a few more inches of cover.  Suddenly, he stuck a metallic object.  He felt with his fingers and carefully pried loose a metal object made of sterling silver.  It was a crucifix left behind by the soldier who had been the previous occupant of the foxhole.
