21st birthday – in 1940. They agree to be faithful to each other until then, though to Mabel "It seems so long" ("Oh, here is love, and here is truth"); Frederic departs. Mabel steels herself ("No, I'll be brave") and tells the police that they must go alone to face the pirates. They muse that an outlaw might be just like any other man, and it is a shame to deprive him of "that liberty which is so dear to all" ("When a felon's not engaged in his employment"). The police hide on hearing the approach of the pirates ("A rollicking band of pirates we"), who have stolen onto the estate, intending to take revenge for the Major-General's lie ("With cat-like tread"). Just then, Major-General Stanley appears, sleepless with guilt, and the pirates also hide ("Hush, hush! not a word"), while the Major-General listens to the soothing breeze ("Sighing softly to the river"). The girls come looking for him. The pirates leap out to seize them, and the Pirate King urges the captured Major-General to prepare for death. The police rush to their defence but are easily defeated. The Sergeant has one stratagem left: he demands that the pirates yield "in Queen Victoria's name"; the pirates, overcome with loyalty to their Queen, do so. Ruth appears and reveals that the pirates are "all noblemen who have gone wrong". The Major-General is impressed by this and all is forgiven. Frederic and Mabel are reunited, and the Major-General is happy to marry his daughters to the noble ex-pirates after all ("Poor Wand'ring Ones" (reprise)).
