While Ferdinand and the English allies kept the French busy in the Rhineland, Prussia had to contend with Sweden, Russia, and Austria. There remained a possibility that Prussia could lose Silesia to Austria, Pomerania to Sweden, Magdeburg to Saxony, and East Prussia to Poland or Russia: an entirely nightmarish scenario. In particular, East Prussia was cut off from the rest of Prussia by of Polish territory, and seemed an easy target, but some Russian court officials—notably Chancellor Alexey Bestuzhev-Ryumin—opposed Russia's entry into what seemed like a largely western European dispute. Bestuzhev-Ryumin did not trust the Prussians, but also had little liking for the French or the British. In this conflict, which grew out of the major realignment of European power diplomacy, it was difficult to determine if the enemy of an enemy was a friend.
