All this time his mind was busy with a fresh scheme, nothing short of a concerted insurrection of all the captives in Algiers, numbering about 25,000, who were to overpower the city, and to plant the Spanish flag on its towers. His measures seem to have been taken with sufficient prudence and foresight to give them a fair chance of success, bold as the idea was, but treachery as usual caused the downfall of everything. Why, under such repeated provocation, the cruel Azan Aga did not put him to a frightful death it is hard to understand, but in his 'Captive's Story,' Cervantes himself bears testimony to the comparative moderation of the Dey's behaviour towards him. 'Though suffering,' he says, 'often, if not indeed always, from hunger and thirst, the worst of all our miseries was the sight and sound of the tortures daily inflicted by our master on our fellow-Christians. Every day he hanged one, impaled another, cut off the ears of a third; and all this for so little reason, or even for none at all, that the very Turks knew he did it for the mere pleasure of doing it; and because to him cruelty was the natural employment of mankind. Only one man did he use well, and that was a Spanish soldier, named Saavedra, and though this Saavedra had struck blows for liberty which will be remembered by Moors for many years to come, yet Azan never either gave him stripes himself, nor ordered his servants to do so, neither did he ever throw him an evil word; while we trembled lest for the smallest of his offences the tyrant would have him impaled, and more than once he himself expected it.' This straightforward account of matters inside the bagnio is the more valuable and interesting if we recollect that Cervantes' great-grandmother was a Saavedra, and that the soldier alluded to in the text was really himself. It is impossible to explain satisfactorily the sheathing of the tiger's claws on his account alone; did Cervantes exercise unconsciously a mesmeric influence over Azan? Did Azan ascribe his captive's defiance of death and worse than death to his bearing a charmed life? Or did he hold him to be a man of such consequence in his own country, that it was well to keep him in as good condition as Azan's greed would permit? We shall never know; only there remains Cervantes' emphatic declaration that during the five long years of his captivity no man's hand was ever lifted against him. Meanwhile, having no more money wherewith to ransom his son, Rodrigo de Cervantes made a declaration of his poverty before a court of law, and set forth Miguel's services and claims. In March 1578, the old man's prayer was enforced by the appearance of four witnesses who had known him both in the Levant and in Algiers and could testify to the truth of his father's statement, and a certificate of such facts as were within his knowledge being willingly offered by the Duke of Sesa, the King, Philip II., consented to furnish the necessary ransom.
