Six days after Pancho Villa and his cross-border raiders attacked Columbus, New Mexico, U.S. general John J. Pershing led a punitive expedition into Mexico to pursue him.

Francisco "Pancho" Villa was a Mexican revolutionary. He was a key figure in the Mexican Revolution, which forced out President and dictator Porfirio Díaz and brought Francisco I. Madero to power in 1911. When Madero was ousted by a coup led by General Victoriano Huerta in February 1913, Villa joined the anti-Huerta forces in the Constitutionalist Army led by Venustiano Carranza. After the defeat and exile of Huerta in July 1914, Villa broke with Carranza. Villa dominated the meeting of revolutionary generals that excluded Carranza and helped create a coalition government. Emiliano Zapata and Villa became formal allies in this period. Like Zapata, Villa was strongly in favor of land reform, but did not implement it when he had power.

Columbus is an incorporated village in Luna County, New Mexico, United States, about 3 miles (5 km) north of the Mexican border. It is considered a place of historical interest, as the scene of a 1916 attack by Mexican general Francisco "Pancho" Villa that caused the United States to send 10,000 troops there in the Mexican Expedition. Columbus's population was 1,664 at the 2010 census.

General of the Armies John Joseph Pershing, nicknamed "Black Jack", was an American army general, educator, and founder of the Pershing Rifles. He served as the commander of the American Expeditionary Forces (AEF) during World War I from 1917 to 1920. In addition to leading the AEF to victory in World War I, Pershing served as a mentor to many in the generation of generals who led the United States Army during World War II, including George C. Marshall, Dwight D. Eisenhower, Omar Bradley, Lesley J. McNair, George S. Patton, and Douglas MacArthur.

The Pancho Villa Expedition—now known officially in the United States as the Mexican Expedition, but originally referred to as the "Punitive Expedition, US Army"—was a military operation conducted by the United States Army against the paramilitary forces of Mexican revolutionary Francisco "Pancho" Villa from March 14, 1916, to February 7, 1917, during the Mexican Revolution of 1910–1920.
