The Miracle Did Not Happen

 Seven Years' War ended. 1760 – Russian army takes Berlin. 1761 - fall of the main Prussian sea fortress of Kolberg. Prussian army was totally destroyed, main part of territory – occupied by Russians and Austrians. East Prussia had been officially incorporated into the Russian Empire. Only a miracle could save Frederick II and his kingdom.

 1762 – death of the Russian Empress Elizaveta Petrovna. New emperor Pyotr III makes peace with his idol Frederick and removes its troops from Prussia. Anti-Prussian union breaks up. Prussia and Great Britain wins the war.

 And what if the miracle did not happen? What if Elizaveta lived a little longer, and “Union of tree skirts” wins the Seven Years War?
