Where is Poland? 
There is no reference to the Polish-Lithuanian Commonwealth (I added a couple sentences) despite the fact that the events were of great relevance to the Poles and several battles were fought in the western part of the country. The province of Silesia was ethnically Polish with German and Czech minorities, lied directly between Poland and Saxony whose king was elected king of the Commonwealth. A commentary by a knowledgeable historian would help: the country could field armies of tens of thousands yet remained neutral when its main ally - Saxony was being destroyed, while Prussia grew on the backbone of the old Polish provinces to attain the status of a major power.
