I want to know the answer to the following question:
At its zenith, the imperialist forces controlled all but how many states in Mexico?
All the background I'm provided with is that "Maximilian was deeply dissatisfied with General Bazaine's decision to abandon the state capital of Chihuahua and immediately ordered Agustín B. Billaut to recapture the city.". Is that enough to answer the question?
Answer: no
