 Baden-Powell had also published a number of popular books on military scouting, including "Aids to Scouting for NCOs and Men", published in 1899.Though written for non-commissioned officers, it became a best-seller and was used by teachers and youth organisations.In the years after the war Baden-Powell broached the idea of a new youth organisation with a number of people, including William Alexander Smith, founder of the Boys' Brigade, with whom he discussed setting up a Boys Brigade Scouting achievement.
