The Battle of Cuautla was a battle between the forces of Emiliano Zapata and the federal army of the Mexican government that took place in the state of Morelos from May 11–19, 1911, during the Mexican Revolution. It has been described as the "six of the most terrible days of battle in the whole Revolution". Eventually, the remains of the defending "Golden Fifth" regiment, the Fifth Cavalry Regiment of the Federal Army, withdrew and Zapata took control of the town.[2] The Zapatista victory convinced Porfirio Díaz to come to terms with Francisco Madero, agree to the Treaty of Ciudad Juárez and resign as president.
