Davidson-Cadillac armored car

The Davidson-Cadillac armored car was developed on a Cadillac chassis by Royal Page Davidson and the cadets of the Northwestern Military and Naval Academy in Highland Park, Illinois. The first vehicle was developed in 1909 and by 1915 the academy had a fleet of eight vehicles consisting of a scout car, two communications cars, a kitchen car, a hospital car, a balloon destroyer, a quartermaster's car and a fully armoured car. To convince the military that a mechanized army was the way to go, Davidson and some cadets drove the fully armoured car along with seven support cars for 34 days from the academy to the Panama-Pacific International Exposition (1915) being held in San Francisco, California.
