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."
War of the Austrian Succession
The year 1743 opened disastrously for the forces of the new Holy Roman Emperor, Charles VII. The French and Bavarian armies were not working well together, and Field Marshal Broglie had been placed in command of the allied army in Bavaria. This created tension between Broglie and the Bavarian commanders. Broglie openly quarrelled with the Bavarian field marshal Friedrich Heinrich von Seckendorff. No connected resistance was offered to the converging march of Prince Charles's army along the Danube, Khevenhüller from Salzburg towards southern Bavaria, and Prince Lobkowitz from Bohemia towards the Naab. The Bavarians, under the command of Count Minuzzi, suffered a severe reverse at the town of Simbach near Braunau on 9 May 1743 at the hands of Prince Charles of Lorraine.
