The Correct Episode Order of “Return to the Planet of The Apes”

I have been watching the “Return to the Planet of The Apes” animated series, from 1975-1976, on Hulu. I realized they were out of order, so I went to IMDB to see what the proper order is. They are also out of order there, nor do they have a description of every episode. There was only one season, just thirteen episodes. I have pieced together, based on events in the series, what I think the order is supposed to be.

Series Description

Hulu Summary: Astronauts traveling aboard the NASA spacecraft Venture leave planet Earth in 1975 and return in the year A.D. 3979 only to learn that intelligent, technologically advanced apes now rule the planet. This relatively short lived series was based on “La Planète des Singes” (The Monkey Planet) by Pierre Boulle. Unlike its predecessors, Return to the Planet of the Apes is able to place the apes in a society that is not primitive and realize Boulle’s original style and setting. Filmation contributes its trademark animation and the great writing makes the show enjoyable.
