THE FACTS ABOUT Cinco de Mayo
Cinco de Mayo is not Mexican Independence Day, a popular misconception. In 1861, Benito Juárez—a lawyer and member of the indigenous Zapotec tribe—was elected president of Mexico. At the time, the country was in financial ruin after years of internal strife, and the new president was forced to default on debt payments to European governments.
In response, France, Britain and Spain sent naval forces to Veracruz, Mexico, demanding repayment. Britain and Spain negotiated with Mexico and withdrew their forces.
France, however, ruled by Napoleon III, decided to use the opportunity to carve an empire out of Mexican territory. Late in 1861, a well-armed French fleet stormed Veracruz, landing a large force of troops and driving President Juárez and his government into retreat.
The Battle of Puebla
Certain that success would come swiftly, 6,000 French troops under General Charles Latrille de Lorencez set out to attack Puebla de Los Angeles, a small town in east-central Mexico. From his new headquarters in the north, Juárez rounded up a ragtag force of 2,000 loyal men—many of them either indigenous Mexicans or of mixed ancestry—and sent them to Puebla.
The vastly outnumbered and poorly supplied Mexicans, led by Texas-born General Ignacio Zaragoza, fortified the town and prepared for the French assault. On May 5, 1862, Lorencez gathered his army—supported by heavy artillery—before the city of Puebla and led an assault.
The battle lasted from daybreak to early evening, and when the French finally retreated they had lost nearly 500 soldiers. Fewer than 100 Mexicans had been killed in the clash.
Although not a major strategic win in the overall war against the French, Zaragoza’s success at the Battle of Puebla on May 5 represented a great symbolic victory for the Mexican government and bolstered the resistance movement. In 1867—thanks in part to military support and political pressure from the United States, which was finally in a position to aid its besieged neighbor after the end of the Civil War—France finally withdrew.
The same year, Austrian Archduke Ferdinand Maximilian, who had been installed as emperor of Mexico in 1864 by Napoleon, was captured and executed by Juárez’s forces. Puebla de Los Angeles was renamed for General Zaragoza, who died of typhoid fever months after his historic triumph there.
