Greetings,
Mr. m. I doubt it. Perhaps if you were at Mexican Wells...
It celebrates the defeat of the French rearguard as they were leaving Mexico. The unit was a French Foreign Legion contingent. They fought to the last two men. The Mexicans offered them surrender and safe passage to honor their bravery. The last two men demanded to march out under arms and bearing the body of their dead Sergeant or they would continue to fight. They did so. The Sergeants skeletal hand is carried to this day when the Legion marches in review.
