At a "Pastoral Fete" at Mr. Bantison's house outside Bath, Lady Mary is still smitten with Beaucaire, although she has many suitors. Lucy finally gets Molyneux alone, to get him to promise to be hers alone for the evening, when he is summoned away by Beaucaire. Lucy accuses him of going to another woman but he denies it in a romantic song. But the summons is a trick of Winterset. Once Molyneux has gone, he denounces Beaucaire as the barber. One by one all of the suitors attack Beaucaire, and are all wounded. An assault by the massed servants of his opponents threatens to defeat Beaucaire, when Francois and his fellow servants join in the battle and repulse the attackers. Lady Mary, believing herself deceived, storms off. Beaucaire is seriously wounded.
