In 2365, he was assigned to the USS Yamato. He served under Captain Donald Varley as a first officer. He recorded a number of captain's logs, which were later seen in a list sorted by stardate on Captain Jean-Luc Picard's monitor on aboard the USS Enterprise-D.
According to Varley, after he ordered a course to Iconia, Garber questioned the wisdom of his captain in giving this order as it violated the Romulan Neutral Zone. Later, he was killed when his ship self-destructed. (TNG: "Contagion", okudagram)
