"Get In The Arena"

When I was a young boy up through High School, I liked to watch boxing - I even boxed  some myself.   But there was one crucial thought to keep close to myself - Be Prepared, and Don't Quit.   This story is about 1 American Cavalry that had one big problem - they had no horses to ride in their battle - they were horseless!   This story message?   When the fight is upon you, do not be just a watcher - Get in the Arena!
