For all those celebrating 5th may here the information:
The Battle of Puebla (Spanish: Batalla de Puebla; French: Bataille de Puebla) took place on 5 May 1862, near Puebla City during the Second French intervention in Mexico. The battle ended in a victory for the Mexican Army over the French Army. The French eventually overran the Mexicans in subsequent battles, but the Mexican victory at Puebla against a much better equipped and larger[5] French army provided a significant morale boost to the Mexicans and also helped slow the French advance towards Mexico City.
The Mexican victory is celebrated yearly through a festival on the same date as the battle. It is primarily celebrated in the Mexican state of Puebla,[6][7][8][9] where the holiday is celebrated as El Día de la Batalla de Puebla (English: The Day of the Battle of Puebla).[10][11][12] There is some limited recognition of the holiday in other parts of the country. In the United States, this holiday has evolved into the very popular Cinco de Mayo holiday, a celebration of Mexican heritage.
