History.com "Cinco de Mayo", includes multiple videos.
"Cinco de Mayo—or the fifth of May—commemorates the Mexican army's 1862 victory over France at the Battle of Puebla during the Franco-Mexican War (1861-1867). A relatively minor holiday in Mexico, in the United States Cinco de Mayo has evolved into a celebration of Mexican culture and heritage, particularly in areas with large Mexican-American populations. Cinco de Mayo traditions include parades, mariachi music performances and street festivals in cities and towns across Mexico and the United States."
...While many believe that the holiday of Cinco de Mayo is a celebration of Mexico's Independence Day, this is an incorrect assumption.
