Why did Baden Powell start scouts?

Col. BP at the time of his vision, used young men for great responsibility during the siege of Mafeking in South Africa. He saw that these teens were reliable and eager to learn, no matter what economic status or education they processed. Upon returning England, young men were not challenged, in the promoted and knighted "Lord" BP's mind. Boys wanted to learn more about scouting, tracking, spying and other tactics. BP founded the scouting movement with this vision in mind.
