After the Peace of Dresden of 1745, the Prussians had completed the works on the fortifications of Neisse. The fortifications of Cosel had also been extended so that they could resist an attack. Schweidnitz had also been transformed from an important depot into a real fortress. Finally, important improvements had also been made to the fortifications of Glatz, while very minor improvements had been made to those of Brieg and Breslau.

|In 1747, Frederick II had concluded a defensive alliance with Sweden against Russia.
On June 5 1741, France and Prussia had signed a 15 years long alliance in Breslau. Thus this treaty would come to an end on June 5 1756.
In 1756, when the French Court learned of the alliance of Prussia with Great Britain, it decided not to renew its treaty with Prussia and concluded an alliance with Austria instead.
