As Ferracute would not accept this doctrine, but sprang to his feet proposing a continuation of the fight, the struggle was renewed.
"Quath Ferragus: 'Now ich wot Your Christian law every grot; Now we will fight; Whether law better be, Soon we shall y-see, Long ere it be night.'" _Roland and Ferragus_.
Roland, weary with his previous efforts, almost succumbed beneath the giant's blows, and in his distress had recourse to prayer.

He was immediately strengthened and comforted by an angelic vision and a promise of victory.

Thus encouraged, he dealt Ferracute a deadly blow in the vulnerable spot.

The giant fell, calling upon Mohammed, while Roland laughed and the Christians triumphed.
The poem of Sir Otuel, in the Auchinleck manuscript, describes how Otuel, a nephew of Ferracute, his equal in size and strength, came to avenge his death, and, after a long battle with Roland, yielded to his theological arguments, and was converted at the sight of a snowy dove alighting on Charlemagne's helmet in answer to prayer.

He then became a devoted adherent of Charlemagne, and served him much in war.
Charlemagne, having won Navarre, carried the war to the south of Spain, where the Saracens frightened the horses of his host by beating drums and waving banners.
