The Battle of Portmán, sometimes referred to by other names such as the Battle off Cartagena and the Battle of Escombrera Island, was a confrontation during the Cantonal Rebellion between the naval forces of the Canton of Cartagena and those of the central government of the Spanish First Republic on 11 October 1873 in which a Cantonal squadron attempted to break a central government blockade of Cartagena. The battle took place in the Mediterranean Sea off Cape Palos near Portmán, Spain. Although no ships were lost on either side, the Cantonal squadron failed to break the blockade and retreated into port at Cartagena.
