I want to know the answer to the following question:
What good fortune from Russia assisted Frederick the Great?
All the background I'm provided with is that "Frederick the Great’s personal reputation was enormously enhanced, as his debt to fortune (Russia’s volte-face after Elizabeth’s death) and to the British subsidy were soon forgotten while the memory of his energy and his military genius was strenuously kept alive.". Is that enough to answer the question?
Answer: yes
