The Legend of the Headless of Montemor-o-Velho

Mr. Martinho and Mr. Gregorio remember:

In Montemor-o-Velho during the Moorish invasion, a fortress was besieged. When the supplies finished, them men sadly decapitated their families to prevent their capture and torture. With nothing to lose and willing to die, they won the battle. On their return, they miraculously found their families alive.
