Young Indy faces Sean Pertwee as a German captain. Pertwee's father Jon Pertwee later appeared as a German general in The Adventures of Young Indiana Jones: Attack of the Hawkmen (1995)
This episode makes up the second half of The Adventures of Young Indiana Jones: Trenches of Hell (1999) (chapter 8 of 22), the first half being the episode "Somme, Early August 1916".
This episode follows "Somme, Early August 1916" and was in turn supposed to be followed by a third season episode called "Berlin, Late August, 1916", in which Indy's escape back to the front was to be documented.
Indiana Jones is never identified by name in this episode, only by the pseudonyms 'Corporal Defence' and 'Lt. Blanc'.
