Battles of The Austro-Prussian War - Course of The War

Course of The War

The first war between two major continental powers in seven years, this war used many of the same technologies as the American Civil War, including railways to concentrate troops during mobilization and telegraphs to enhance long distance communication. The Prussian Army used von Dreyse's breech-loading needle gun, that could be rapidly loaded while the soldier was seeking cover on the ground, whereas the Austrian muzzle-loading rifles could only be loaded slowly, and generally from a standing position.

The main campaign of the war occurred in Bohemia. Prussian Chief of the General Staff Helmuth von Moltke had planned meticulously for the war. He rapidly mobilized the Prussian army and advanced across the border into Saxony and Bohemia, where the Austrian army was concentrating for an invasion of Silesia. There, the Prussian armies led nominally by King William I converged, and the two sides met at the Battle of Königgrätz (Sadová) on July 3. The Prussian Elbe Army advanced on the Austrian left wing, and the First Army on the centre, prematurely; they risked being counter-flanked on their own left. Victory therefore depended on the timely arrival of the Second Army on the left wing. This was achieved through the brilliant staffwork of its Chief of Staff, Leonhard Graf von Blumenthal. Superior Prussian organization and élan decided the battle against Austrian numerical superiority, and the victory was near total, with Austrian battle deaths nearly seven times the Prussian figure. Austria rapidly sought peace after this battle.

Except for Saxony, the other German states allied to Austria played little role in the main campaign. Hanover's army defeated Prussia at the Second Battle of Langensalza on 27 June 1866, but within a few days they were forced to surrender by superior numbers. Prussian armies fought against Bavaria on the Main river, reaching Nuremberg and Frankfurt. The Bavarian fortress of Würzburg was shelled by Prussian artillery, but the garrison defended its position until armistice day.

The Austrians were more successful in their war with Italy, defeating the Italians on land at the Battle of Custoza (June 24) and on sea at the Battle of Lissa (July 20). Garibaldi's "Hunters of the Alps" defeated the Austrians at the Battle of Bezzecca, on July 21, conquered the lower part of Trentino, and moved towards Trento. Prussian peace with Austria forced the Italian government to seek an armistice with Austria, on August 12. According to Treaty of Vienna, signed on October 12, Austria ceded Venetia to France, which in turn ceded it to Italy (for details of operations in Italy, see Third Italian War of Independence).
