Meanwhile, Gelimer remained blockaded by Pharas at the mountain stronghold of Medeus, but, as the blockade dragged through the winter, Pharas grew impatient. He attacked the mountain stronghold, only to be beaten back with the loss of a quarter of his men. While a success for Gelimer, it did not alter his hopeless situation, as he and his followers remained tightly blockaded and began to suffer from lack of food. Pharas sent him messages calling upon him to surrender and spare his followers the misery, but it was not until March that the Vandal king agreed to surrender after receiving guarantees for his safety. Gelimer was then escorted to Carthage.
