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.

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.
