http://en.wikipedia.org/wiki/Battle_of_Camar%C3%B3nThe Battle of Camarón occurred on 30 April 1863, between the French Foreign Legion and the Mexican army. In this battle the French Foreign Legion made its legend. A small infantry patrol led by Captain Jean Danjou, Lt Maudet and Lt Vilain, numbering 62 soldiers and 3 officers was attacked and besieged by a force that may have eventually reached 2,000 Mexican infantry and cavalry, and was forced to make a defensive stand at the nearby Hacienda Camarón, in Camarón de Tejeda, Veracruz, Mexico.
