Plan of Agua Prieta

He did not have a military record in the Mexican Revolution, and critics saw the choice as a way that Carranza could continue to wield power even though no longer president of Mexico.

[4] The Plan of Agua Prieta outlined a series of charges against the Carranza regime, to articulate their grievances in written form to be distributed and to rally others to join their cause.

Others joined as well, including Lázaro Cárdenas of Michoacan, who had served under Calles in the Revolution, and held a command in Veracruz state at the time.

[6] The plan empowered De la Huerta to appoint interim governors in those states that aligned with or were defeated by the Liberal Constitutionalist Army.

Support for the Plan was widespread across the country: more than three-quarters of the Army rejected Carranza and joined the rebellion.

As De la Huerta's Liberal Constitutionalist Army made rapid progress toward Mexico City, Carranza refused to negotiate or surrender and fled the capital by train in May 1920, headed for the port of Veracruz, where he intended to set up a temporary seat of government as he had earlier during the Revolution.

The train was attacked repeatedly as it left the capital and, arriving at Aljibes, Puebla, was unable to continue because of sabotage to the tracks.
