Written by Douglas Camfield & Robert Kitts, the storyline for this six-part story was submitted to the production office on 18 September 1967, although Camfield & fellow BBC worker Kitts had developed the outline in 1965 due to Camfield's dismay at another sub-standard script, and would probably have been directed by Camfield himself. The story saw the Doctor arrive in Normandy just prior to the D-Day landings. It would feature a plan to stop the Nazis from using a form of matter teleportation. Only a draft script for episode 1 would be written. It went through several rewrites until 1967 when it was finally abandoned due to producer Innes Lloyd moving on and the writers both having other commitments. This story was given individual episode titles even though this practice had stopped with "The Savages" in 1966. Episode titles were listed as: "The Secret Army", "Chateau of Death", "Lair of the Werewolf", "Friend Or Foe", "Village of the Swastika", and "Crossfire".
