Canto VIII. During this battle a great storm arises, and the Christians, who, notwithstanding their courage, have been worsted, beat a retreat, finding on their return to camp that one of their companions, defeated and mortally wounded, has despatched a messenger to carry his sword to Rinaldo. The Italian force thereupon accuses Godfrey of having done away with Rinaldo, but he not only succeeds in refuting such an accusation, but sentences his chief detractor to death.

Canto IX. Sultan Solyman of Nicae, who has joined Sultan Aladine of Jerusalem, now comes to attack the Christians by night, assisted by many fiends, but the archangel Michael warns the crusaders of what is coming and enables them to get the better of their foes by bringing back the troops which followed Armida to Damascus. In this encounter a Christian knight slays a page of the sultan, who, seeing this child dead, experiences such grief that, after avenging his death, he wishes to withdraw temporarily from the battle.

"Let Godfrey view once more, and smile to view
My second exile;—soon shall he again
See me in arms return'd, to vex anew
His haunted peace and never stable reign:
Yield I do not; eternal my disdain
Shall be as are my wrongs; though fires consume
My dust, immortal shall my hate remain;
And aye my naked ghost fresh wrath assume,
Through life a foe most fierce, but fiercer from the tomb!"

Canto X. The sultan, after journeying part way back to Egypt, pauses to rest, and is visited by a wizard, who spirits him over the battle-field and back to Jerusalem in a magic chariot. This pauses at a hidden cave, the entrance to an underground passage, by which they secretly enter the sultan's council chamber.

Ismeno shot the lock; and to the right
They climb'd a staircase, long untrod, to which
A feeble, glimm'ring, and malignant light
Stream'd from the ceiling through a window'd niche;
At length by corridors of loftier pitch
They sallied into day, and access had
To an illumined hall, large, round, and rich;
Where, sceptred, crown'd, and in dark purple clad,
Sad sat the pensive king amid his nobles sad.

Solyman, overhearing as he enters some of the nobles propose a disgraceful peace and the surrender of Jerusalem, hotly opposes such a measure, and thus infuses new courage into their breasts.

Canto XI. Meantime Godfrey of Bouillon, having buried his dead, questions the knights who were lured away by Armida, and they relate that, on arriving near the Dead Sea, they were entertained at a sumptuous banquet, where they were given a magic draught, which transformed them for a time into sportive fishes. Armida, having thus demonstrated her power over them, threatened to use it to keep them prisoners forever unless they would promise to abjure their faith. One alone yielded, but the rest, delivered as prisoners to an emissary from Egypt, were met and freed from their bonds by the brave Rinaldo, who, instead of accompanying them back to camp, rode off toward Antioch.

The Christians now prepare for their final assault, and, advised by Peter the Hermit, walk in solemn procession to the Mount of Olives, where, after singing hymns, all devoutly receive Communion. Thus prepared for anything that may betide, they set out on the morrow to scale the city walls, rolling ahead of them their mighty engines of war, by means of which they hope to seize the city.

Most of the Crusaders have laid aside their heavy armor and assumed the light gear of foot-soldiers the better to scale the walls, upon which Clorinda is posted, and whence she shoots arrow after arrow at the assailants. Wounded by one of the missiles flung from the wall, Godfrey seeks his tent, where, the physician failing to extract the barb, an angel brings a remedy from heaven which instantly cures the wound.

Canto XII. After awhile, seeing she does not do as much execution as she would like, Clorinda proposes to Argantes that they steal out of the city by night, and by chemical means set fire to the engines with which the Christians are threatening to capture the city. Willingly Argantes promises to accompany her in this perilous venture, but her slave, hoping to dissuade her, now reveals to her for the first time, the story of her birth, and informs her she is the daughter of a Christian. He adds her dying mother besought him to have her child baptized, a duty he had failed to perform, although repeatedly warned by visions to repair his neglect. But, although similar visions have frequently haunted the dreams of Clorinda herself, she persists in her undertaking to set fire to the war machines.
