It was a unit composed of European immigrants who deserted or defected from the US Army during the Mexican-American War (1846-1848). They are unique in the sense that they showed sympathy for the Mexican cause, and were a formidable fighting force which is considered the single unit which caused most casualties to the American side during the war. After being defeated due to sheer numbers (8,500 Americans vs. 3,800 Mexicans) and lack of ammunition during the Battle of Churubusco (August 20, 1847), most of them were executed. Nowadays, they are considered heroes in Mexico.
