Angelica treasures up their history in her mind, as useful to the purpose which she had in hand, and on the door of the tower opening, to admit a new victim, slips the ring into her mouth and escapes.

Being again at liberty, she sets out for the garden of Dragontina, and, entering it unseen, disenchants Orlando, Brandimart, and the rest, by a touch of her talisman. These she conjures to assist her in the recovery of her kingdom, and all depart together for Albracca.

In the meantime a revolution had taken place in the citadel of that metropolis. Truffaldino, always false, had surprised Sacripant, and the other wounded princes in their beds, and cast them into prison. This done, he sent a messenger to Agrican, with an offer to deliver the fortress into his hands. Agrican, however, received the proposal in a manner little expected by Truffaldino, whom he reviled as a traitor and a coward; declared that he would never be indebted to fraud, for that which he could have by force; said he knew the extremities of the garrison, which must soon be his, and declared, that as soon as the place was in his possession, he would hang up Truffaldino by the heels.

Soon after this, Orlando, with his friendly squadron of knights (nine in number), with Angelica in the midst of them, arrives before Albracca; and charging through the camp of Agrican, arrives at the foot of the citadel: this is, however, kept against them by Truffaldino, who appears upon the walls, and declares that he will only admit Orlando and his followers, on their swearing to protect him for ever from the vengeance of Sacripant and the others; whom, for his own safety, he has been under the necessity of casting into prison. Orlando indignantly refuses; but, conjured by Angelica, consents; as do the others who accompany him; and after the oath has been taken as enjoined, the squadron enters the fortress.

This, however, is found so destitute of food, that a sally is resolved upon for the purpose of provisioning it: it is to be made by Orlando, Brandimart, Adrian, Clarion, and Uberto of the Lion; while Gryphon and Aquilant remain at home for the protection of Angelica and the citadel.

Orlando and his friends having made the warder lower his drawbridge, ride boldly towards the enemy's camp; and Agrican, marking their scanty number, bids his squadrons stand apart, and leave a fair field for himself and Orlando, who engage in a desperate duel. While they are employed in this, with little vantage on either side, and to their mutual astonishment at finding themselves so equally matched, a loud larum is heard from the citadel, which announces the arrival of succours.

This was an army, raised by Galaphron, for the relief of Albracca; the vanguard commanded by a vassal giant; the second body by Marphisa, a young Indian queen, who had made a vow in her infancy, never to lay aside her armour, till she had taken three kings prisoners, to wit, Charlemagne, Gradasso, and Agrican; while the rear-guard was conducted by Galaphron himself. The van-guard, led by the giant, is immediately engaged with the besiegers; and its leader, armed with an immense hammer, deals such destruction amongst their ranks, that all is speedily in confusion and disarray.

Agrican, witnessing the rout of his followers, now entreats Orlando, for his lady's love, that their combat may be suspended till the morrow, in order to give him an opportunity of rallying the fugitives. This Orlando not only grants, but offers to assist him in his design. The offer is, however, courteously declined by Agrican, who, flying in pursuit of the giant, unhorses him, and leaves him desperately wounded to the daggers of his followers. He himself charges the troops who come under the giant's conduct; and the tide of battle is turned.

No attempt to stop the confusion of the vanguard is made by Marphisa, who this time was retired from the field, and sleeping under a tree.

But first the queen her chamber-wench bespoke.
"Attend to my command," Marphisa said,
"And when thou seest our Indian army broke,
"And Galaphron, its royal leader, dead,
"When all these things shall be, 'twere time I woke,
"Then, bring my steed and rouse me from my bed.
"But till these things shall be, such care delay,
"'Tis then this single arm shall change the day."
