(Elwyn Brook-Jones), whose sons want to marry them which, with Canford's collusion, had been O'Reilly's plan all along. The officers go to muster their forces, while Harry and Canford go to visit the Emir. Gates gets there on her own and enters the palace by helping to carry in the laundry. To the Emir's displeasure, the girls are defending themselves quite well. Harry, Canford and Gates offer to reason with the girls, and are allowed to visit them for five minutes: when they can't provide results, the Emir's men attack again, again with little success. Just as this fight is ending, the army arrives but is promptly captured. Things look bleak, when they hear the St. Trinian's school song in the distance, followed by the arrival of the fourth-form girls in army vehicles, who smash their way into the compound, forcing the Emir and his forces to run away. Back in Britain, the girls and Sgt. Gates are hailed as heroes. In Barset, Gates, after 16 years of being engaged, is about to get married, when the ceremony is interrupted with news that the girls are again burning down the school, and Kemp-Bird runs off, even as Gates is walking down the aisle. As the film ends, the staff at the Ministry and the officers at the East Arabian army camp are all doing a pastoral dance to calm themselves.
