In December 1938 the "GERC" was scheduled to take part in General Vicente Rojo Lluch's "Plan P", an ambitious project of an offensive campaign in Extremadura that would have taken place at the same time as a disembarkment within the enemy lines in Motril, along with diversionary attacks in other places of Andalusia and the Madrid Front. However, in the face of the opposition of General Miaja and other Republican commanders to the implementation of the whole plan, it was not carried out to its full extent and the only action taken was the Battle of Valsequillo which resulted in failure shortly before having been initiated.
