Well, I seem to vaguely remember an episode where, because of his code-breaking skills, he was ordered back to England and the rest of Hogan's crew had to come up with the idea of how to get him out without ruining Colonel Klink's "perfect record" at Stalag 13.
I can't remember whether he was "transferred" to another camp from which Hogan's and his crew broke him out and got him to England or he was "killed" when "the car that he was riding in" exploded".
I have been watching the episodes on MeTV when I get the chance. Unfortunately, it isn’t every day.
I think I will have to check out the dvds and watch the episodes in order. I should have plenty of time to watch them when I drop Uverse in a month.
