The Second Silesian War took place from 1744 to 1745. The Austrians had lost Silesia to Prussia in the Battle of Mollwitz. This was the time when the Austrians, under the command of Field Marshal Otto Ferdinand von Abensberg und Traun, attempted to gain control of Silesia once again. The Prussians were again led by King Frederick the Great, who had continued the expansionist policy of his father.
The Battle of Hohenfriedberg on June 4, 1745, was fought through a “series of separate actions”, with each part of the Prussian army fighting its own uncoordinated battle. Because the Saxons and Austrians were unable to support each other during the battle, they “Allowed the Prussians time to recover from their own tactical lapses and win a victory that was significant enough to give the battle’s name to one of Germany’s greatest marches”, After the Prussian victory, Frederick did not pursue the opposing armies.
In the Battle of Soor on September 29, 1745, Frederick's Prussians faced an Austrian army led by Prince Charles Alexander of Lorraine with 39,000 men. Frederick tried to obtain Graner-Koppe from Prince Charles where the Prussians met with cannon fire. The Prussians won after a closely fought battle consisting of a series of attacks and regimental fighting.
Whilst Frederick was sure the war was over, Empress Maria Theresa had not given up her claims to Silesia. “She became even more determined to put Prussia in its proper place by force of arms”. Seeking peace with France and Russia, she hoped to beat Prussia and gain control of Silesia once again. Frederick was informed of her movements to regain control and “responded with a pre-emptive strike” against her Saxon allies. This was the Battle of Kesselsdorf which was won by the Prussian general Leopold I, Prince of Anhalt-Dessau; the Saxons were led by Frederick Augustus Rutowsky.
The signing of the Treaty of Dresden on December 25, 1745, ended the Second Silesian War between Austria, Saxony, and Prussia. Maria Theresa recognized Frederick the Great’s sovereignty over Silesia and the Duchy of Glatz in return for "Frederick's agreement to support the election of her consort Francis Stephen as Emperor of Germany". recognition of Francis]] as Holy Roman Emperor”.
