Query: According to the Russian-Austrian pact of 1746, what would happen to Silesia in the event of hostilities with Prussia?
Context: On June 2, 1746, Austria and Russia concluded a defensive alliance that covered their own territory and Poland against attack by Prussia or the Ottoman Empire. They also agreed to a secret clause that promised the restoration of Silesia and the countship of Glatz (now Kłodzko, Poland) to Austria in the event of hostilities with Prussia. Their real desire, however, was to destroy Frederick’s power altogether, reducing his sway to his electorate of Brandenburg and giving East Prussia to Poland, an exchange that would be accompanied by the cession of the Polish Duchy of Courland to Russia.
