Two others episodes of the same season ('The Prince from the Phone Company', 'Hello, Zollie') have characters mention strategic plans for the ongoing North African Campaign (June 1940-May 1943). An episode of season 1 ('How to Cook a German Goose by Radar') mentions the Allied invasion of Sicily (July-August, 1943) as a recent event. The characters learn of the end of this battle in a season 4 episode ('Guess Who Came to Dinner?'). For example one episode of season 5 ('The Big Gamble') and three episodes of season 6 ('To Russia Without Love', 'That's No Lady, That's My Spy', 'Kommandant Gertrude') mention the ongoing Battle of Stalingrad (August 1942- February, 1943).

But the events as depicted are not in order, the timeline jumps back and forth. The plots of several episodes even rely on said events.
