# First Army (Austro-Prussian War)

The First Army was a Prussian formation during the Austro-Prussian War. Being a wartime organization of the Prussian Army; it afterwards was demobilized.

## Formation

For the Austro-Prussian War the Prussians organized their forces into three, and eventually four, field armies. Helmuth von Moltke, Chief of the Prussian General Staff, assigned four corps to attack the area of the Austria-allied kingdoms of Hanover and Saxony. The command of the First Army was given to Prince Friedrich Karl of Prussia, a nephew of King William of Prussia. The young General der Kavallerie had served in the First Schleswig War and Second Schleswig War and already received the prestigious Pour le Mérite with oak leaves. Chief of Staff was to be Generalleutnant Konstantin Bernhard von Voigts-Rhetz, who was an intelligent but opinionated officer.

## Course of war

During the war the First Army did not operate effectively in the opinion of the war-directing General Staff. Prince Friedrich Karl's marching orders strained the army's supply lines and prevented a link with Second Army. Fortunately, the First Army was able to link up with the Army of the Elbe, commanded by Karl Eberhard Herwarth von Bittenfeld. On June 28 both armies operated against Mnichovo Hradiště which turned into the Battle of Münchengrätz. The prince then ordered the 3rd Division to march to Jičín. Even though the campaign was successful many men died before reaching the battlefields. The combined operation of two armies worsened the already bad supply situation. When the armies marched separately again the First Army was the first in the Battle of Königgrätz, fighting against the Austrians under Ludwig von Benedek until the Second Army of Crown-Prince Frederick William of Prussia arrived.
