I want to know the answer to the following question:
How would one characterize the encounter with the Russian army in 1757?
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: no
