On May 5, 1862, a small army of about 5,000 ill-equipped Mestizos and Zapotec Indians defeated the French army at Puebla, a small town in southern Mexico. The nearly miraculous Mexican victory temporarily stopped France’s progression toward Mexico City and its ultimate goal of an empire in Mexico. Unfortunately, the triumph was short-lived. As soon as Napoleon learned of the humiliating defeat, he deployed an additional 30,000 troops. Within a year, he'd taken over Mexico City and installed the Archduke Maximilian of Austria as ruler of the new empire.
