XIII
The holy priests within Biserta's wall,
Pray with their grieving people, and in tears,
Aye beat their bosoms, and for succour call
Upon their Mahomet, who nothing hears.
What vigils, offerings, and what gifts withal
Were promised silently, amid their fears!
What temples, statues, images were vowed,
In memory of their bitter woes, aloud!

XIV
And, when the cadi hath his blessing said,
The people arms and to the rampart hies.
As yet reposing in her Tithon's bed
Aurora was, and dusky were the skies;
When to their posts, their several troops to head,
Here Sansonetto, there Astolpho flies.
And when they hear Orlando's signal blown
Assault with furious force Biserta's town.

XV
Washed by the sea, upon two quarters, were
The city walls, two stood on the dry shore,
Of a construction excellent and rare,
Wherein was seen the work of days of yore:
Of other bulwarks was the town nigh bare;
For since Branzardo there the sceptre bore;
Few masons at command, and little space
That monarch had to fortify the place.

XVI
The Nubian king is charged by England's peer,
With sling and arrow so the Moors to gall,
That none upon the works shall dare appear;
And that, protected by the ceaseless fall
Of stone and dart, in safety cavalier
And footman may approach the very wall;
Who loaded, some with plank, with rock-stone some,
And some with beam, or weightier burden, come.

XVII
This and that other thing the Nubians bore,
And by degrees filled-up that channel wide,
Whose waters were cut off the day before,
So that in many parts the ooze was spied.
Filled is the ditch in haste from shore to shore,
And forms a level to the further side.
Cheering the footmen on the works to mount,
Stand Olivier, Astolpho, and the Count.

XVIII
The Nubian upon hope of gain intent,
Impatient of delay, nor heeding how
With pressing perils they were compassed, went
Protected by the sheltering boar and sow.
With battering ram, and other instrument,
To break the gate and make the turret bow,
Speedily to the city wall they post,
Nor unprovided find the paynim host.

XIX
For steel, and fire, and roof, and turret there,
In guise of tempest on the Nubians fell,
Which plank and beam from those dread engines tear,
Made for annoyance of the infidel.
In the ill beginning, and while dim the air,
Much injury the christened host befell;
But when the sun from his rich mansion breaks,
Fortune the faction of the Moor forsakes.

XX
The assault is reinforced on every side,
By Count Orlando, both by sea and land:
The fleet, with Sansonetto for its guide,
Entered the harbour, and approached the strand;
And sorely they with various engines plied,
With arrows and with slings, the paynim band;
And sent the assailants scaling-ladder, spear,
And naval stores, and every needful gear.

XXI
Orlando, Oliviero, Brandimart,
And he, in air so daring heretofore,
Do fierce and furious battle on that part,
Which lies the furthest inland from the shore:
Each leads a portion of those Aethiops swart,
Ordered in equal bands beneath the four,
Who at the walls, the gateways, or elsewhere,
All give of prowess shining proofs and rare.

XXII
So better could be seen each warrior's claim,
That in confused in combat there and here.
Who of reward is worthy, who of shame,
To a thousand and to watchful eyes is clear.
Dragged upon wheels are towers of wooden frame,
And others well-trained elephants uprear,
Which so o'ertop the turrets of the foe,
Those bulwarks stand a mighty space below.
