Хуан Мануэль
The siege now developed into a stalemate. The Moors were not strong enough to break out of Gibraltar, nor to assault the Castilians from the north across their ditch. They also did not have the naval power required to outflank the Castilians by sea or to break the naval blockade of Gibraltar, which was bringing the garrison close to starvation. The Castilians did not have the strength either to storm Gibraltar or to drive away Mohammad IV's troops on the Sierra Carbonera. Alfonso XI also received the news that three powerful nobles – Juan Núñez III de Lara, Juan Alfonso de Haro and Juan Manuel, Prince of Villena – had revolted against him and were ravaging the king's own lands. Both sides thus found that they had pressing reasons to reach a peace agreement.
