It Kershaw's Brigade history the story of several body servants is told that accompanied Lee's Army into Pennsylvania. These servants would range far and wide each day while their master marched from one place to another foraging for the evening meals and would almost always return to the confederate camps at night, WHY? They had the oppertunity to make good their excapes anywhere in Pennsylvania. Where they too dumb to know that fact? I don't think so.
When Lee's army retreated back to Virginia do you think that anyone cared about making sure that these servants came along too? Most of these servants opperated with only minimal supervision.
I know the story of one servant who was given to his masters son as the son left for the army. The servants served the masters son for 3 years until the son was killed leading a charge. The servant traveled back to the sons home to carry the sons personal effects to the sons wife.
The servant then traveled to find the father. By that time the father's home was in Union occupied territory. The servant upon arriving at his old masters house found that the master had moved to another stae to avoid the yankee's. Having crossed into the Union lines the servant had been emancipated and told by the yankee's that he was a free man. But the servant still felt that he had a duty to preform and crossed back into Confederate territory to find his old master and tell him the news of his sons death. The servant found his old master in Texas and remained with him until the end of the war. The master returned to his old home after the war and the servant returned with him. and lived with his old master and took care of him untiil the master died.
I would call that Loyality. The servant became a businessman going into business with several of his old masters friends.
