out, and Mainwaring suggests rowing out there. Mr Alberts says they will be dashed to pieces on the rocks, but Mainwaring doesn't care - until Mr Alberts says that there is no boat in the first place. Walker arrives with the Lewis Gun, and Hodges suggests shooting it out, but Mainwaring says it will kill the men in the lighthouse. Walker suggests asking a friend of his at the power company to black out the entire county, but Mainwaring rebuffs the suggestion as it will draw too much attention, so instead they decide to put the nearby transformer out of action via the fuses, but only succeed in fusing the whole of the Jolly Roger Pier, but not the lighthouse. The disgruntled lighthouse keeper appears and informs them that it is powered by its own generator. As the telephone line to the lighthouse is cut off, Mainwaring rings the telephone exchange to try to get it reconnected, but struggles to make himself plain to the lady at the exchange. Walker talks to her and convinces her to reconnect the line, as the previous lighthouse keeper was a contact of his during his pre-war smuggling activities. Mainwaring rings Jones, and tells him to go down to the generator room and turn off the lighthouse from there. However, they are taking a long time about it and Hodges soon hears the sound of German bombers approaching. He eventually persuades them to shoot the light with the Lewis Gun. Mainwaring declares that he himself will do it as they are his men and readies the gun, not knowing that Godfrey is in the way. However, just as Mainwaring is about to fire, the generator is shut down just in time. Hodges remarks that they have not heard the last of this, and Wilson adds that they will all be a lot poorer once GHQ learns about it. Mainwaring assures him there is no evidence of their activities, until Walker points out the results of them attacking the transformer: a destroyed tin hat, three dirty uniforms and Mainwaring's cap falling apart.
