But even before the departure of Rodrigo, Cervantes had been laying other plans. He had, somehow or other, managed to make acquaintance with the Navarrese gardener of a Greek renegade named Azan, who had a garden stretching down to the sea-shore, about three miles east of Algiers, where Cervantes was then imprisoned. This gardener had contrived to use a cave in Azan's garden as a hiding place for some escaped Christians, and as far back as February 1577 about fifteen had taken refuge there, under the direction of Cervantes. How they remained for so many months undiscovered, and how they were all fed, no one can tell; but this part of the duty had been undertaken by a captive renegade called El Dorador, or the Gilder, to whom their secret had been confided. Meanwhile, Rodrigo had proved faithful to his trust. He had equipped a frigate for sea, under the command of a tried soldier, Viana by name, who was familiar with the Barbary coast. It set sail at the end of September, and by the 28th had sighted Algiers. From motives of prudence the boat kept to sea till nightfall, when it silently approached the shore. The captives hailed it with joy, and were in the act of embarking, when a fishing craft full of Moors passed by, and the rescue vessel was forced to put to sea. Meanwhile, Cervantes and the fugitives in the cave had to return disheartened into hiding, and await another opportunity. But once lost, the opportunity was gone for ever. Before any fresh scheme could be concerted, El Dorador had betrayed the hiding place of the Christians and their plan of escape to the cruel Dey or King Azan, who saw in the information a means to satisfy his greed. According to the law of the country, he was enabled to claim the escaped slaves as his own property (except Cervantes, for whom he paid 500 crowns), and with a company of armed men presented himself before the cave. In this dreadful strait Cervantes' courage never faltered. He told the trembling captives not to fear, as he would take upon himself the entire responsibility of the plan. Then, addressing Azan's force, he proclaimed himself the sole contriver of the scheme, and professed his willingness to bear the punishment. The Turks were struck dumb at valour such as this, in the presence of the most dreadful torments, and contented themselves with ordering the captives into close confinement at the bagnio, hanging the gardener, and bringing Cervantes bound to receive his sentence from the Dey Azan himself. The threats of impalement, torture, mutilation of every kind, which Cervantes well knew to be no mere threats, had no effect upon his faithful soul. He stuck to the story he had told, and the Dey, 'wearied by so much constancy,' as the Spanish historian says, ended by loading him with chains, and throwing him again into prison.
