Düppeler Schanzen
The Prussian Army crushed Danish forces in the Battle of Dybbøl during the Second Schleswig War (1864), allowing Prussia and Austria to claim Schleswig and Holstein, respectively. Disputes orchestrated by the Prussian Minister President, Otto von Bismarck, led to the Austro-Prussian War (1866). The needle guns of the Prussian infantry were highly successful against the Austrians, who were defeated at Königgrätz. Under the leadership of Moltke, the Prussian Army then proved victorious over France in the Franco-Prussian War (1870). Unlike the Austrians, the French had the powerful Chassepot rifle, which outclassed the Prussian needle gun. However, the Prussian artillery was effective against the French, who were frequently flanked or surrounded by the mobile Prussians. Patriotism in Prussia from the victories began to undermine liberal resistance to absolutism.
