General Jacques Beauchamp (? - 1914) was the commander of the French Expeditionary Force during the 1914 Hundred Day War between France and the United States of Mexico.
General Beauchamp led the F.E.F. in its conquest of the Mexican port city of Tampico, Durango on 28 June 1914. After the arrival of reinforcements on 15 July, Beauchamp led the F.E.F. on a drive for Mexico City.
Beauchamp's drive on Mexico City was halted on the outskirts of Chapultepec by the arrival of General Emiliano Calles. In the Battle of Chapultepec on 28 August 1914, Beauchamp sent his cavalry to reconnoiter Calles' flanks. Calles sent a squadron of airmobiles to bomb Beauchamp's artillery. At the same time, Mexican soldiers attacked the F.E.F. from two sides, blowing up French machine gun emplacements and laying down a barricade of barbed wire around the French force. Within two hours, the Mexicans had succeeded in completely encircling Beauchamp's army with barbed wire. Beauchamp led three charged against the barbed wire barricades, each of which was driven back by Mexican mortars, machine guns, and airmobiles. Beauchamp himself was killed in the third charge, after which the French ended their attempts to break out of their encirclement.
The French drive on Mexico City ended the next morning, when Beauchamp's second-in-command, General Pierre Bordagary, surrendered unconditionally to Calles.
