The friends pursued their route, and ere long Flordelis discovered, by signs which were known to her, that they were approaching the waters of Oblivion, and advised them to turn back, or to change their course.  This the knights would not hear of, and, continuing their march, they soon arrived at the bridge where Orlando had been taken prisoner.

The damsel of the bridge appeared as before with the enchanted cup, but Astolpho, forewarned, rejected it with scorn.  She dashed it to the ground, and a fire blazed up which rendered the bridge unapproachable.  At the same moment the two knights were assailed by sundry warriors, known and unknown, who, having no recollection of anything, joined blindly in defence of their prison-house.  Among these was Orlando, at sight of whom Astolpho, with all his confidence not daring to encounter him, turned and fled, owing his escape to the strength and fleetness of Bayard.

Florismart, meanwhile, overlaid by fearful odds, was compelled to yield to necessity, and comply with the usage of the fairy.  He drank of the cup and remained prisoner with the rest.  Flordelis, deprived of her two friends, retired from the scene, and devoted herself to untiring efforts to effect her lover’s deliverance.  Astolpho pursued his way to Albracca, which Agrican was about to besiege.  He was kindly welcomed by Angelica, and enrolled among her defenders.  Impatient to distinguish himself, he one night sallied forth alone, arrived in Agrican’s camp, and unhorsed his warriors right and left by means of the enchanted lance.  But he was soon surrounded and overmatched, and made prisoner to Agrican.

Relief was, however, at hand; for as the citizens and soldiers were one day leaning over their walls they descried a cloud of dust, from which horsemen were seen to prick forth, as it rolled on towards the camp of the besiegers.  This turned out to be the army of Sacripant, which immediately attacked that of Agrican, with the view of cutting a passage through his camp to the besieged city.  But Agrican, mounted upon Bayard, taken from Astolpho, but not armed with the lance of gold, the virtues of which were unknown to him, performed wonders, and rallied his scattered troops, which had given way to the sudden and unexpected assault.  Sacripant, on the other hand, encouraged his men by the most desperate acts of valor, having as an additional incentive to his courage the sight of Angelica, who showed herself upon the city walls.

There she witnessed a single combat between the two leaders, Agrican and Sacripant.  In this, at length, her defender appeared to be overmatched, when the Circassians broke the ring, and separated the combatants, who were borne asunder in the rush.  Sacripant, severely wounded, profited by the confusion, and escaped into Albracca, where he was kindly received and carefully tended by Angelica.

The battle continuing, the Circassians were at last put to flight, and, being intercepted between the enemy’s lines and the town, sought for refuge under the walls.  Angelica ordered the drawbridge to be let down, and the gates thrown open to the fugitives.  With these Agrican, not distinguished in the crowd, entered the place, driving both Circassians and Cathayans before him, and the portcullis being dropped, he was shut in.
