Juan Manuel, Prince of Villena
It was not until June that Alfonso was able to put a relief force into the field. His senior advisers had argued against staging a relief expedition on the grounds that it would mean fighting both Granada and Fes, which they saw as too much of a risky venture. After eight days of arguments in Seville, Alfonso got his way and was able to persuade his rebellious vassal Juan Manuel, Prince of Villena to support him against the Moors. He marched his army to Jerez, where they camped by the River Guadalete, four days' march from Gibraltar. It was, however, already too late for the defenders.
