From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
HCA is advised that the emperor of Mexico has conferred upon him the title of Commander of the order of Notre Dame de Guadaloupe. When the emperor is executed in the following year, HCA is informed that if he shows himself in Mexico wearing this order he would be shot, but that it is safe to wear it in Austria.
