Austro-Prussian War
The pretext for the conflict was found in the dispute between Prussia and Austria over the administration of Schleswig-Holstein, which the two of them had conquered from Denmark and agreed to jointly occupy at the end of the Second Schleswig War in 1864. When Austria brought the dispute before the German Diet and also decided to convene the Diet of Holstein, Prussia declared that the Gastein Convention had thereby been nullified and invaded Holstein. When the German Diet responded by voting for a partial mobilization against Prussia, Bismarck claimed that the German Confederation was ended. Crown Prince Frederick "was the only member of the Prussian Crown Council to uphold the rights of the Duke of Augustenburg and oppose the idea of a war with Austria which he described as "fratricide"". Although he supported unification and the restoration of the medieval empire, "Fritz could not accept that war was the right way to unite Germany."
Battle of Strehla
The Battle of Strehla was a military engagement fought during the Seven Years' War between the Kingdom of Prussia and Austria. The battle was fought near the town of Strehla in Saxony, Germany.
In August 1760, Fredrick the Great of Prussia and his army made ready to repel further Austrian incursions into Prussian territory. When the Austrian offensive did come, it came in Prussian-occupied Silesia. However, a second Austrian army of 25,000 men also began advancing upon Frederick's holdings in Eastern Saxony, putting the Prussians in danger of being caught in a large pincer movement. To counter this threat, Frederick dispatched Lt. General Johann Dietrich von Hülsen and 12,000 men to hold the west bank of the Elbe river at the town of Strehla while Frederick dealt with the Austrians in Silesia. Five days before the engagement at Strehla, Frederick and his army defeated the Austrian forces in Silesia at the Battle of Liegnitz, effectively rendering the Austrian plan to pincer the Prussian forces defunct.
