Descirption: Before the War of 1866 the name of Helmuth Von Moltke was scarcely known outside the Prussian army. His appointment as Chief of the General Staff was in many ways surprising, and he certainly did not himself expect it. He was thus put at the head of a military institution that was already to some extent superior to its counterparts elsewhere; he was to turn it into a formidable machine that became, in his hands, very nearly invincible. This was due to number of factors which coincided with his appointment. Among these were the many advances in military technology and logistics on the one hand, and on the other the emergence of Otto Von Bismarck as Minister-President of Prussia, with whom Moltke had a crucial, if occasionally uneasy, relationship.
