Having obtained the required items and made your escape from the château in the Wings of War, you must now escape occupied France and return to Blighty.
It is thought that Salamander Software ceased trading before they could release this game, though in the last days of Salamander it is possible that some copies were sold by mail order. At the time of writing one version of the game is known to exist. This version has been described as a pre-release version because it lacks several programming tricks that Salamander used at that time on their released programs, however it could be that this version is the mail order version with the lack of the usual programming tricks explained by the desperate state of Salamander at that time. How close this version is to the original vision of the final product is not known.
If the game had been released in full then the packaging might have cleared up a mystery - at the end of Wings of War you escape with six items, these items are not mentioned in The White Cliffs of Dover even though they are the reason for your mission. Perhaps in the time-frame between the two games you rendezvoused with a Lysander, the aeroplane having enough space to take the items but not you as well, leaving you to make your own way back home.
