I want to know the answer to the following question:
How did Frederick respond to the loss of a supply convoy?
All the background I'm provided with is that "East Prussia had been occupied by Russian forces over the winter and would remain under their control until 1762, although Frederick did not see the Russians as an immediate threat and instead entertained hopes of first fighting a decisive battle against Austria that would knock them out of the war.". Is that enough to answer the question?
Answer: no
