North America 1916: Pancho Villa Expedition

The coalition that had deposed Huerta collapsed soon after taking Mexico City. A year of fighting followed, in which the once powerful general "Pancho" Villa was defeated and reduced to fighting a guerrilla campaign in the north. In 1916, he crossed the border and raided New Mexico. In response, the US sent a punitive expedition south under General Pershing in an ultimately futile and unpopular effort to hunt Villa down.
