Allo! Allo!

We learnt that RAF airmen Fairfax and Carstairs are from 402 Squadron.

Madame Fanny tells Edith that Vincent Van Gogh (whom she liked to call "Bobby") was in love with her, and threatened to emasculate himself if she would not marry him. She says she later recieved an ear in the post. If you don't know already, Vincent Van Gogh (1853-1890) was a real-life Dutch post-Impressionist artist who suffered mental problems, leading to his suicide aged 37. Legend says he cut his own ear off during a seizure on Christmas Eve 1888, wrapping it in newspaper and giving it to a prostitute at the local brothel he frequented. The inference here is that Madame Fanny was that prostitute.

Herr Von Smallhausen was educated at Oxford University, in England.

This is the only episode of series three where you see the exterior of the cafe in the studio, and it's apparent that a few more changes made to the set - there are now long brown doors behind Rene, whereas before there was a window. The doors are also surrounded by a large amount of ivy. Also, the chairs and tables are arranged differently.

The title of this episode alludes to the 1963 film "The Great Escape" (starring Steve McQueen) in which several hundred British prisoners of war plan a mass escape.

Though generally wildly unrealistic, this episode actually lists a technical adviser in the credits. Air Commodore E.S. Chandler A.F.C. apparently advised on the scenes in the POW camp.

This is the last episode with Francesca Gonshaw (Maria). Her departure, however, is not explained in this episode.
