Dad's Army 1970 S04E08

Episode: The Two and a Half Feathers. An elderly ex-soldier called Clarke comes to join the platoon and, by coincidence, it turns out that he and Jones were in the same regiment in Sudan back in the 1890s. However he paints a picture of a cowardly Jones who left him to his fate when he was captured by Dervishes, and soon after Jones receives two feathers, signifying cowardice, through the post. The corporal then tells his story in a flashback where all the participants look like members of the present platoon.
