I want to know the answer to the following question:
In what battle did Murad II leave as the victory in 1448?
All the background I'm provided with is that "On 10 November 1444, Murad II defeated the Hungarian, Polish, and Wallachian armies under Władysław III of Poland (also King of Hungary) and John Hunyadi at the Battle of Varna, the final battle of the Crusade of Varna, although Albanians under Skanderbeg continued to resist.". Is that enough to answer the question?
Answer: no
