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. On December 11, 1865, Billaut with a force of 500 men took control of the city. By January 31, 1866 Billaut was ordered to leave Chihuahua, but he left behind 500 men to maintain control.
