 Under Moltke the Prussian army achieved victory in the Austro-Prussian War (1866) and the Franco-Prussian War (1870–71), the latter campaign being widely regarded as a classic example of the conception and execution of military strategy.In addition to exploiting railroads and highways for manoeuvre, Moltke also exploited the telegraph for control of large armies.He recognised the need to delegate control to subordinate commanders and to issue directives rather than specific orders.
