to comply ("Some years ago") or incur the guilt of fratricide. The defiant Ida replies that, although Hilarion saved her life and is fair, strong and tall, she would rather die than be his bride ("To yield at once to such a foe"). Act III Princess Ida reviews her student troops' readiness to meet Hildebrand's soldiers in battle, but the terrified girls admit that they are afraid of fighting ("Death to the invader!"). Princess Ida is disgusted by their lack of courage and vows that, if necessary, she will fight Hildebrand's army alone ("I built upon a rock"). Her father, King Gama, arrives with a message that Hildebrand prefers not to go to war against women. He reveals that Hildebrand has been torturing him by keeping him in luxury and giving him nothing to complain about ("Whene'er I spoke sarcastic joke"). He suggests that, instead of subjecting her women to all-out war, she pit her three strong, brave brothers against Hilarion and his friends, with Ida's hand to depend on the outcome. Ida is insulted to be "a stake for fighting men" but realises that she has no alternative. Hildebrand's forces enter, together with Gama and his three sons ("When anger spreads his wing"). Hilarion, Cyril and Florian are still in their women's robes, and King Gama and his sons ridicule them. In preparation for battle, Gama's sons shed their heavy armour, saying that it is too uncomfortable for combat ("This helmet I suppose"). The fight ensues, with Hilarion, Cyril and Florian defeating Gama's sons ("It is our duty plain"). Her wager lost, Ida yields to Hilarion and bitterly asks Lady Blanche if she can resign her post with dignity. The delighted Blanche, who will succeed her as head of the university, assures her that she can. Ida laments the failure of her "cherished scheme", but King Hildebrand points out the flaw in her logic: If you enlist all women in your cause, And make them all abjure tyrannic Man, The obvious question then arises, "HowIs this Posterity to be provided?" Princess Ida admits, "I never thought of that!" Hilarion makes an emotional appeal, urging her to give Man one chance, while Cyril observes that if she grows tired of the Prince, she can return to Castle Adamant. Lady Psyche says that she, too, will return if Cyril does not behave himself, but Melissa swears that she will not return
