In 2270, Bemis, Spock, and security guard Latrobe crewed an Enterprise shuttlecraft. They were trying to locate a top-secret Starfleet weapon hidden in a missing shuttle from the USS Yorktown, which landed somewhere on sparsely populated Mevinna. Pyretimite on the class M planet disrupted scanners and communications, forcing flyover searches. After searching for nearly ten hours, they landed near an apparent crash site. Bemis confirmed that it was the crash site fifteen minutes later. He called Latrobe to point out something. Suddenly, both were disintegrated when a force field formed directly on them. It had been activated by renegade Andorians intent on stealing the weapon. (TOS - The New Voyages short story: "The Enchanted Pool")
- Bemis was not explicitly identified as a security guard, but given the nature of the mission, it was extremely likely.
