Mainwaring is extremely annoyed that all the platoon - except Godfrey, who was too slow - have used up all their ammunition firing in vain at a low-flying German aeroplane. An inquiry is ordered - along with a new case of ammunition, which duly arrives. The captain in charge of the inquiry, which takes place in the church hall in competition with choir practice, feels it a waste of his time but talks the men through what happened. Jones says he gave the order to shoot. Mainwaring corrects him by saying 'Fire', which the platoon does, making a hole in the roof.
