Cause

Tensions between Prussia and Austria over the governance of the German Confederation and the administration of Schleswig-Holstein led to the outbreak of the Austro-Prussian War in June 1866. Austria's Ludwig von Benedek, unfamiliar with the Bohemian terrain and troops under his command, accepted command reluctantly, placing the Austrian army at a strategic disadvantage from the outset.

Event

On 3 July 1866, approximately 285,000 Prussian troops engaged around 240,000 Austrian forces near Hradec Králové in Bohemia. The Prussian First Army under Prince Friedrich Karl and guards forces under Wilhelm Hiller von Gaertringen drove into the Austrian centre at Swiepwald and Chlum, destroying 38 of 49 Austrian infantry battalions. Superior Prussian training, Moltke's tactical doctrine, and effective use of rail transport overcame deficiencies in Prussian artillery.

Consequence

The Austrian army was compelled to retreat by 15:00, before Prussian flanking forces could fully engage, effectively ending major resistance in the war. The decisive Prussian victory led directly to Austria's exclusion from German affairs and paved the way for Prussian-led unification of Germany, fundamentally altering the political order of Central Europe.
