The battle that gave birth to the foreign legion
at the beginning, legion was mostly used as connon fodder and french regular army had little respect for legionnaires.
For those interested in the legion etrangere, i suggest that you read this:
http://en.wikipedia.org/wiki/Battle_of_Camar%C3%B3n
you will find countless websites talking of the battle of camerone (camaron in spanish)
After this infamous battle, which is celebrated each year by the legionnaires, the foreign legion gained huge respect in france.
this battle sounds like the antique battle where 100 soldiers for sparta could defeat 10,000 persians
