In 2268, Commodore Enwright ordered the USS Enterprise to his station. He contacted the Enterprise before they could initiate contact. When asked by CaptainJames T. Kirk what the reason for the diversion was, Enwright told him that the explanation was beaming aboard the Enterprise as they spoke and might have already materialized.
The voice of the unseen commodore was provided by James Doohan.
According to the first draft of the script, dated 30 November1967, Enwright beamed aboard the Enterprise along with Wesley to brief Spock and James T. Kirk in the transporter room. The character was ultimately cut by the final draft, and his lines were given to Wesley.
According to the aforementioned first draft, he was described as follows: "Enwright is fiftyish, perhaps visibly too heavy for his uniform. He is an administrative officer, and a good one, but he's never been a command pilot."
