US Intervention in Mexico: 1914 or 1916?

Correction: The Mexican Punitive Expedition (1916–1917)

The US did not intervene in Mexico in 1914.

The Mexican Punitive Expedition (US invasion/occupation) began in March 1916, led by General Pershing, pursuing Pancho Villa after his raid on Columbus, New Mexico. It lasted until early 1917.

1914 saw the Tampico Affair and Veracruz occupation (April–November 1914), but the major cross-border expedition started in 1916.
