Newly declassified British intelligence files reveal the ripples of alarm that spread through the country as Hitler Youth cyclists toured Britain in 1937. Reports of sightings poured in from local police amid fears the teenagers might be two-wheeled "spyclists" scouting the country for a future invasion. The Hitler Youth group aimed to instill the Nazis' racist and xenophobic ideals into young Germans, through a mix of indoctrination, outdoor activities and military-style training. Before World War II, members of the group visited Britain, and MI5 documents released Monday by the National Archives show that its leaders sought closer ties with the Boy Scout movement.
