In the novelization of Star Trek: The Motion Picture, written by Gene Roddenberry, Admiral Kirk states in his forward that during his five years in command of Enterprise, a total of 96 of his crew perished. No persons were killed in Star Trek: The Animated Series that depicted the remainder of the five-year mission, making the on-screen Enterprise death toll stand at fifty-seven (not counting revivals, and including the deaths of Leslie and Galloway).
