The Prussian King Wilhelm I, Bismarck and General Helmuth von Moltke the Elder observe the largest encirclement in military history: On July 3, 1866, approximately 180,000 Austrians faced 200,000 Prussians. 1,500 guns were used. With the victory of the Prussian army, the way for a unification opened under Prussian leadership - without Austria
