9 MAY--This Day in US Military History

1916 – President Woodrow Wilson mobilizes the National Guard of Arizona, New Mexico and Texas to patrol their borders with Mexico as Brigadier General John J. Pershing led an Army expedition into northern Mexico to try to capture or kill the bandit leader Pancho Villa and his group.

In March, Villa and his men raided the town of Columbus, NM, killing a number of soldiers and civilians before slipping back across the border. Soon these Guardsmen would be joined by Guard units coming from all the states to a total 158,000 men. While their main mission was to secure the border the Army used this partial mobilization to train the Guard in large unit formations almost impossible to conduct in normal peacetime exercises for just a few days. This training paid great dividends when America committed its Guardsmen to combat in France after our entry in World War I.
