That doesn't make sense. Explain.
Good reading - notice the end of the second paragraph. :
Etymology
The term is derived from Nicolas Chauvin, a semi-mythical soldier under Napoleon Bonaparte who is supposed to have served in the French Revolution (1789–1800) and the Napoleonic Wars. Despite the unpopularity of Bonapartism in Restoration France, Chauvin was said to be an ardent supporter and was often seen wearing a violet in his lapel, the symbol of his deposed Emperor. According to the myth, he remained fanatically loyal despite his poverty, disability, and the abuse he suffered.
Many writers and historians falsely attribute to Chauvin the exploits of other Bonapartists. It is claimed that he served in the Old Guard at Waterloo, which is unlikely considering his age and the severity of his disabilities. When the Old Guard was surrounded and made its last stand at La Belle Alliance, he supposedly shouted in defiance to a call for their honorable surrender: "The Old Guard dies but does not surrender!", implying blind and unquestioned zealous devotion to one's country [or other group of reference]. This apocryphal phrase was in fact attributed to the Old Guard's commander, Pierre Cambronne who later asserted that his actual reply was "Merde!" ("s**t!").[2]
The origin and early usage indicate that chauvinisme was coined to describe excessive nationalism, which the original French term continues to do. The term entered public use due to a satirical treatment of Chauvin in the French play La Cocarde Tricolore (The Tricolor Cockade).
