In the Franco-Prussian War, the Guard Corps participated in the Battle of Gravelotte-Saint Privat on 18 August 1870. The attack on the broad plain was made hastily and without supporting artillery fire. Even the subsequent envelopment of the enemy by the Royal Saxon Army troops could not therefore be exploited. The Guard Corps, under the leadership of August, was assigned to Albert, Crown Prince of Saxony, and participated in the Battle of Sedan, and in part in the Siege of Paris. Chief of Staff during the later campaign was still Ferdinand von Dannenberg, by now promoted to Major General.
