I want to know the answer to the following question:
Millions of Muslims left the empire and migrated to what places?
All the background I'm provided with is that "This resulted in around 400,000 Muslims fleeing with the retreating Ottoman armies (with many dying from cholera brought by the soldiers), and with some 400,000 non-Muslims fleeing territory still under Ottoman rule.". Is that enough to answer the question?
Answer: no
