“ After some years of regimental service he came under the notice of Moltke, the newly appointed chief of the general staff, as an exceptionally gifted soldier, and at the outbreak of the war against Austria in 1866 he was appointed major on the staff of the II. Army (crown prince of Prussia) . In this capacity he took part in the campaign on the upper Elbe and in the battle of Koniggratz. Promoted shortly after this to the rank of lieutenant-colonel, he was in 1867 placed at the head of a section of the general staff, becoming thereby one of Moltke’s principal confidential assistants. ”
