The success of fast-moving Blitzkrieg tactics by the Nazi war machine depended on high mobility. With their on- and off-road capabilities, motorcycles became an important component of the Nazi war machine’s arsenal making a particularly significant impact in French and Russian campaigns. The motorcycles were used in a variety of roles including patrolling, intelligence gathering, and police duties in occupied Europe. Motorcyclists could be found in every unit of an infantry and Panzer division including headquarters which had a motorcycle messenger platoon. Their versatility also enabled them to survey enemy positions until coming under fire before reporting back with vital intelligence relating to enemy locations and strengths. The German industry produced wide range of motor-bikes for military use. By 1938 some 200,000 motorcycles were produced in Germany and occupied territories. The principal makes included BMW, DKW, NSU, Triumph, Victoria, and Zundapp. Sidecar combinations, often mounted with an MG34/42 machine gun, also made the bike a very effective weapon. By describing in words and contemporary images the role of the German motorcycle and motorcyclists during the Second World War, this Images of War book fills an overlooked gap in coverage of Nazi military capability. It emphasizes that the German military perfected the use of motorcycles and employed them more widely than any other army.
