Captain Mainwaring independently, although not always with the best of results. In "A Man of Action", Walmington is cut off when a bomb damages the railway and waterworks. Mainwaring imposes martial law and takes power from the Mayor. Under his law people need permits to take a bath and looters will be shot. He changes position when this power is taken from him by an official from GHQ, describing such an act and the imposition of martial law as "monstrous". Mainwaring often claims to know something, only to be proven wrong almost immediately. Men under him, however, are mostly devoted to him.
