Harold Lewis

Harold Lewis was a Captain aboard the UNSC Las Vegas during the Callisto Incident.

Background
Harris Lewis, on the Las Vegas, was sent to capture the Callisto. However, they were outmaneuvered, and Lewis was killed.

Hunt
After the UNSC Callisto was captured by Insurrectionists, the UNSC sent the UNSC Las Vegas, the UNSC Jericho, and the UNSC Buenos Aires to hunt it down.

Death
On March 2, 2494, they encountered the Callisto in the 26 Draconis System. They all fired six of their seven Ares missiles, and in response, the Insurrectionists maneuvered behind an asteroid, which it then detonated in the direction of the UNSC vessels using a nuclear warhead planted beforehand. The Las Vegas was seriously damaged, and Lewis was killed by the explosion, along with nearly all of the bridge crew.
