Very unlikely. Frederick II of Brandenburg (in history books at that time, also called Prussia - because yes, the area around the Polish city Królewiec once was a part of it, and they even were called kings of Prussia - three of them, that is) had to fight three great powers, not counting the lesser ones. He was competent as a general, but there is a superiority of numbers (which his enemies had) when strategery won't help you anymore. When his last army was trounced between Austrians and French, and he committed suicide, the "kingdom of Prussia" died as well.
