What is the climax of song Roland?

In the epic poem Song of Roland, the climax is the final battle between the Franks and the Saracens. The Saracens, led by King Marsile, have invaded France and are besieging the Frankish city of Zaragoza. The Franks, led by Charlemagne, have come to the city's aid.

The battle is fierce and bloody, and many knights on both sides are killed. Charlemagne himself is wounded, but he continues to fight. Finally, the Franks are victorious, and the Saracens are defeated.

The climax of the poem is significant because it represents the triumph of good over evil. The Franks, who are fighting for justice and righteousness, are victorious over the Saracens, who are fighting for greed and power. The battle also serves as a metaphor for the struggle between Christianity and Islam, which was ongoing at the time the poem was written.
