1854-1864 In 1854, after forty-one years of active service, he was promoted major-general. At
Magdeburg, as at Berlin, his reforming zeal made him many enemies, and in October his youngest and only surviving child died at twenty-six, which affected him deeply. In 1857, he was posted to the command of a guard brigade at Berlin, and thence almost immediately to a divisional command in the I Corps. Early in 1858 he was promoted lieutenant-general, and for the five years that he held this command he devoted himself to cavalry. In 1863, learning that
Adolf von Bonin, his senior by date of rank, but his junior in age and length of service, was to be appointed to the command of the
I Corps, he considered retirement. However, when Bonin took command, Steinmetz was given command of the
II Corps. Shortly afterwards, the
crown prince of
Prussia Frederick William took over II Corps and Steinmetz went to command the
V Corps at
Posen. Soon after this his wife died.
Austro-Prussian War He was promoted to general of infantry in 1864, and led the
V Corps in the
Austro-Prussian War of 1866. It was part of the
Second Army of Crown Prince
Frederick William. On 26 June 1866 Steinmetz and his reinforced corps were ready to enter Austrian territory as the advance guard of the army's left column. In the evening of that day the border was crossed on the road leading from
Glatz to
Bohemia via
Reinerz. On the following day he encountered troops of
Wilhelm von Ramming, the resulting
Battle of Náchod ending in a Prussian victory. He likewise was victorious in the battles of
Skalitz and
Schweinschädel on the following days. His skillful and resolute leadership was displayed in three battles on three successive days. He later opened the way through the mountains in spite of Bonin's defeat at
Trautenau. In 1867, the "Lion of Nachod", as he was popularly called, married Elise von Krosigk (who after his death married Count Bruhl). He was now, for the first time in his life, a fairly wealthy man, having been awarded a money grant for his brilliant services in 1866. About this time he was elected a member of the
North German Confederation parliament.
Franco-Prussian War At the outbreak of the
Franco-Prussian War in 1870, Steinmetz was appointed to command one of the three armies assembled on the
Rhine, the others being led by
Prince Frederick Charles and the crown prince. It was not long before serious differences arose between Steinmetz and Prince Frederick Charles. Steinmetz, embittered by his lifelong struggle against the influences of wealth and position, saw an order to clear the roads for the prince's army as an attempt to crowd a humbler comrade out of the fighting, and various incidents. On 6 August he led the First Army south from his position on the Moselle and moved straight toward the town of
Spicheren, cutting off Prince Frederick Charles from his forward cavalry units in the process. There he encountered the French II Corps under
Frossard, which was fortified between Spicheren and Forbach and was able to stall him until the German Second Army came to the aid of their compatriots and routed the French. Eight days later he again encountered the French army at
Borny-Colombey. At the
Battle of Gravelotte he lost his temper and wasted his troops against a French superior position, nearly causing the defeat of the Prussian armies. After this he was relieved of command and sent home as governor-general of the V and
VI Army Corps districts. As a commander in the Franco-Prussian War and the Battle of Gravelotte, Steinmetz was mentioned a few times in Chapter IV of anti-war short story entitled "Bartek The winner", written by Polish Nobel-awarded writer
Henryk Sienkiewicz. ==Promotion to field marshal and later life==
