Just in case you didn't know:
John S. Mosby. by profession, was a lawyer. After the war he moved out to California and became a lawyer for the
Southern Pacific Railroad and settled in what is now the Los Angeles area.
He also became good friends with the District Attorney. The D.A. owned a large ranch just out side of Los Angeles and Mosby often spent the weekend at the ranch with the D.A.
The D.A.'s young son took to Mosby and they became almost inseparable companions. The young man grew up listening to stories of "The War" that Mosby told him. Matter of fact, when the young man was 15, he and Mosby traveled back to Virginia, Maryland and Pennsylvania and visited many of the Civil War battlefields. Mosby acted as his guide.
For his first year in college, the young man enrolled in Virginia Military Institute and after that transferred to West Point.
Because of Mosby, the young man decided on a military career.
The young mans name?
George S. Patton, Jr.
