Narrative: On June 15, 1919, bandits fired into El Paso from the Mexican side of the
border. American troops moved to put down the bandits—an action that was mildly
protested by the Mexican government. In July, Secretary of State Robert Lansing
issued a formal warning to Mexico that if it could not protect American lives within its
borders, then a greater intervention was imminent. However, as the American military
maintained a presence, the protests from the Mexican government grew stronger. In
August the Mexican government urged the US military to pull out of northern Mexico
and threatened clashes with Carranza troops. On November 30, the United States
heavily fortified its border with Mexico in anticipation for clashes while Mexican
troops were ordered to fire on any American aircraft crossing its border. Small, unveri-
fied attacks occurred between troops, citizens, and bandits within this time frame, and
on February 25, 1920, the Mexican government issued a record of acts of violence
committed against Americans in Mexico, displaying the decreased level since the
formal warning by Secretary Lansing the previous year.
