Query: What characteristic of Saxony caused Europe to be mad?
Context: The Prussians then occupied Saxony; after the Siege of Pirna, the Saxon army surrendered in October 1756, and was forcibly incorporated into the Prussian army. The attack on neutral Saxony caused outrage across Europe and led to the strengthening of the anti-Prussian coalition. The only significant Austrian success was the partial occupation of Silesia.
