• Occupied by an American army under Doniphan, February 28, 1847. Doniphan had been sent by General Kearny to relieve General Wool, who had been dispatched on an expedition against Chihuahua in October, 1846. Wool had, however, failed of his destination. Doniphan took possession of Chihuahua without difficulty, experiencing no opposition. He retained possession of the city and then abandoned it, finding that Wool did not seem likely to join him. His troops were led to New Orleans and there disbanded.
