At the news that the enemy was in sight he rose, and, in spite of the remonstrances of his comrades and superiors, insisted on taking his post, saying he preferred death in the service of God and the King to health.

His galley, the Marquesa, was in the thick of the fight, and before it was over he had received three gunshot wounds, two in the breast and one in the left hand or arm.

On the morning after the battle, according to Navarrete, he had an interview with the commander-in-chief, Don John, who was making a personal inspection of the wounded, one result of which was an addition of three crowns to his pay, and another, apparently, the friendship of his general.
How severely Cervantes was wounded may be inferred from the fact, that with youth, a vigorous frame, and as cheerful and buoyant a temperament as ever invalid had, he was seven months in hospital at Messina before he was discharged.

He came out with his left hand permanently disabled; he had lost the use of it, as Mercury told him in the "Viaje del Parnaso" for the greater glory of the right.

This, however, did not absolutely unfit him for service, and in April 1572 he joined Manuel Ponce de Leon's company of Lope de Figueroa's regiment, in which, it seems probable, his brother Rodrigo was serving, and shared in the operations of the next three years, including the capture of the Goletta and Tunis.
