Because the Spreadsheet is so difficult to read, mainly owing to the bleed-through of the print, this partial spreadsheet containing the more relevant items has been created.

The shaded columns for El Paso and Nogales contain the war materiel that would have passed to the Villistas and Maytorenistas, respectively, of the Convention's forces. If Villa also smuggled arms and ammunition, as claimed by some Villistas, then they would have received even more. And, this does not include what Villa had imported from the end of the embargo in September 1914 up to March 15, 1915, or the materiel that Carranza permitted Villa to receive through Tampico during the summer of 1914 per the Torreón Accords.

Any suggestion that the Conventionist Army lost the Mexican Revolution in 1915 because of an arms embargo selectively imposed by the United States is a lie.

National Archives and Records Administration. U.S. Adjutant General’s Office, Record Group 94, Entry 25, “Villa’s Revolution,” File 2212358, box 7643, September 10, 1915 spreadsheet “Report of Exportations of Arms, Ammunition and Munitions of War through Border Ports into Mexico, March 15, 1915, to September 4, 1915,”

According to the prevailing narrative among Leftists in the academy, the United States of America systematically denied the sale of war materiel to the Conventionists, including the forces of Pancho Villa, Emiliano Zapata, and José María Maytorena.  See for example: John Mason Hart, Revolutionary Mexico: The Coming and Process of the Mexican Revolution (Berkeley and Los Angeles, CA: University of California Press, 1997), pp. 290-301; and Francisco Pineda Gómez, Ejército Libertador, 1915 (México: Ediciones Era, S.A. de C.V., Consejo Natural para la Cultura y las Artes, 2013), pp. 217, 307, 373.

However, as the following spreadsheet PROVES beyond the shadow of a doubt, the  U.S. Army not only  permitted the transit of arms and ammunition to Villa and Maytorena, but kept a running total of what crossed the border to all factions.
