The Cub Scout section was first launched in 1916 as Wolf Cubs. Early in the development of the Scouting movement, there was a need for provision for those too young to join the Boy Scouts at the age of 11. In a number of cases, those too young were not turned away and unofficial junior troops existed in the UK as early as 1909, only a year after the official formation of troops. These boys were often taught simple Scout skills such as tracking, First Aid, simple knots or semaphore and wore a simple uniform of a green cap and dark green or blue jersey.
