Portrait-Photo of 'Jakob Freiherr von Hartmann' (1795-1873) who was a Bavarian general who served in the Austro-Prussian War and Franco-Prussian War. 

During the Austro-Prussian War Bavaria joined the Austrian side and Hartmann as lieutenant-general commanded the 4th Royal Bavarian Division in engagements against the Prussians at Rossdorf and Hettstadt. After the defeat of Austria and its allies, Hartmann was retained in his command. In January 1869 Hartmann was promoted to General der Infanterie.

When the Franco-Prussian War broke out, Bavaria fought on the side of its erstwhile enemy Prussia. Hartmann was given command of the II. Bavarian Army Corps, which was together with its sister Corps - I. Bavarian Army Corps under von der Tann - part of the III Army, led by the Crown Prince of Prussia. Hartmann lead the II Corps in the battles of Wissembourg, Wörth and Sedan. When the German armies neared Paris he fought in engagements at Corbeil, Bourg-la-Reine, Petit-Bicètre and Moulin de la Tour. On 19 September 1870 Hartmann defeated General Ducrot in an engagement at Sceaux.

In July 1871 he was further ennobled a Freiherr. After the end of the war he kept command of his corps until his death.

The photo dates around 1870 and was developed by 'F. Jamrath & Sohn' from Berlin. Interesting original photograph!
