In compliance with orders from Santa Anna, Mexico's Minister of War [[José María Tornel]] issued his December 30 "Circular No. 5", often referred to as the Tornel Decree, aimed at dealing with United States intervention in the uprising in Texas. It declared that foreigners who entered Mexico for the purpose of joining the rebellion were to be treated as "pirates", to be put to death if captured. In adding "since they are not subjects of any nation at war with the republic nor do they militate under any recognized flag," Tornel avoided declaring war on the United States.<ref>Calore (2014), p. 56</ref><ref>Todish  ''et al.''
