The Battle of Contreras, also known as the Battle of Padierna, took place during the August 19–20, 1847, in the final encounters of the Mexican-American War. In the Battle of Churubusco, fighting continued the following day.

Background

During the march on Mexico City, the U.S. army under Major General Winfield Scott found its way north blocked by a strong Mexican force at the "el peñon" (near the current airport of Mexico City). Scott settled down at "peña pobre" on the southwest og Mexico City, and from Zacatepet hill, sent a force west across the "pedregal", a lava field, to the town of San Jerónimo to flank the Valencia's Mexican position at "Rancho Padierna", on Contreras. Mexican commander and President Antonio López de Santa Anna dispatched the "Army of the North" about 5,000 soldiers under Gabriel Valencia to flank the Americans. The Battle of Contreras or Padierna began on August 19 of 1847, and culminated at dawn of August 20, on the outskirts of Mexico City, Padierna, among the neighborhood of San Angel, Contreras and Tlalpan (currently in the area between San Jeronimo, the neighborhood Heroes of Padierna, Anzaldo Dam in peripherals, and the area that today is ironically called "Placid Gardens" in Mexico City. Popular belief generally regarded this battle as a minor one, fought absurdly by the Mexican leadership. Even with the betrayals and quarrels dividing the leadship, there was no doubt as to the courage of the fighters in the field, and it was a battle that, if it had been well planned by the leadship of the Mexican side, could have changed significantly the last days of the war.

Battle

The U.S. attacked and routed Valencia's Army of the North at Contreras. Participating in the attack was Brigadier General Franklin Pierce leading a brigade of regulars. During the fighting Pierce was seriously wounded when his horse fell on him. The Mexican battalions formed part of the remains of the Northern Division (under the command of General Gabriel Valencia), the cavalry of Guanajuato, the forces of General Frontera (died in battle), the guerrilla of Reina (originally from the village of Contreras), and the reinforcement of General Perez from SantaAnna's army.

Aftermath

With the rout of Valencia, the main Mexican position at San Antonio fell back to Churubusco. After the U.S. forces took San Antonio, they began to merge with the forces from Contreras for a further attack on Churubusco.
