Note The area where the main exterior filming took place was also used for the new shots for the end credits (necessitated as the end credits for the previous two series had been filmed in black and white). A reminder of this episode was therefore present for the rest of the series' run, with the cast walking past the trees in front of which the Spanish Captain is briefly seen standing holding a megaphone, and the shot of the platoon running across an open heath was used at the very end of all subsequent episodes under the producer's credit.
