Roland then goes to help the besieged Blois and wins the battle with the leader of the Saracens. In reward, he is granted by the king of France the hand of his royal daughter. But Roland refuses to accept that offer not disclosing the reason. When he finally confesses his nightly tryst to the Bishop of Blois, the bishop and a group of monks intervene on Esclarmonde's arrival, performing an exorcism and in a crucial moment manage to tear off her veil and thus reveal her identity. Feeling betrayed, Esclarmonde, in her bravura aria "Ah Roland, tu m'as trahie, et me voilà... Regarde-les ces yeux", rebukes Roland for his faithlessness. The confrontation scene proceeds with Roland trying at the last moment to use his sword to defend her from the monks. Suddenly, the magic sword shatters to pieces, and Esclarmonde, surrounding herself with a ring of fire and demons, curses Roland and disappears.
