I want to know the answer to the following question:
Where were the Zapatist forces from?
All the background I'm provided with is that "Zapatist forces, which were based in neighboring Morelos had strengths in the southern edge of the Federal District, which included Xochimilco, Tlalpan, Tláhuac and Milpa Alta to fight against the regimes of Victoriano Huerta and Venustiano Carranza.". Is that enough to answer the question?
