When the Austro-Prussian War of 1866 broke out Hindenburg wrote his parents: "I rejoice in this bright-coloured future. For the soldier war is the normal state of things…If I fall, it is the most honorable and beautiful death". During the decisive Battle of Königgrätz he was briefly knocked unconscious by a bullet that pierced his helmet and creased the top of his skull. Quickly regaining his senses, he wrapped his head in a towel and resumed leading his detachment, winning a decoration. He was battalion adjutant when the Franco-Prussian War (1870–71) broke out. After weeks of marching, the Guards attacked the village of Saint Privat (near Metz). Climbing a gentle slope, they came under heavy fire from the superior French rifles. After four hours the Prussian artillery came up to blast the French lines while the infantry, filled with the "holy lust of battle", swept through the French lines. His regiment suffered 1096 casualties, and he became regimental adjutant. The Guards were spectators at the Battle of Sedan and for the following months sat in the siege lines surrounding Paris. He was his regiment's elected representative at the Palace of Versailles when the German Empire was proclaimed on 18 January 1871; at 1.98 m (6 feet 6 inches) tall with a muscular frame and striking blue eyes, he was an impressive figure. After the French surrender he watched from afar the suppression of the Paris Commune.
