However, due to new policies (like conscription), greater populations, and greater national wealth, the nineteenth-century army was composed of an average of 100,000 men. For example, in 1812 Bonaparte led an army of 600,000 to Moscow while feeding off plentiful agricultural products introduced by the turn of the century, such as potatoes. Despite the advantages of mass armies, mobilizing forces of this magnitude took much more time than it had in the past.
