I want to know the answer to the following question:
What happened to Frederick's army at the Battle at Kunersdorf?
All the background I'm provided with is that "Frederick himself lost half his army in the Battle of Kunersdorf (now Kunowice Poland), the worst defeat in his military career and one that drove him to the brink of abdication and thoughts of suicide.". Is that enough to answer the question?
Answer: yes
