Lash's father was a welder on the UNSC Cradle and was killed when it was destroyed during the Battle of Sigma Octanus IV on July 17, 2552. Lash knew his father wanted an opportunity to be a hero during the war, and was glad in a sense that he got the chance to.
Battle of Earth and the Covenant Civil WarEdit
Shortly before the Battle of Earth, Captain Iglesias was injured and undergoing radiation treatment Earthside, forcing Lash to take command. Lash took the UNSC Dusk into the fight during the Battle of Earth .
Lash eventually had to take the Dusk into Slipspace to follow the UNSC In Amber Clad as well as the Prophet of Regret's Assault Carrier. Once they arrived at Installation 05, Lash witnessed the Civil War of the Covenant, as the Second Fleet of Homogeneous Clarity destroyed itself. Lash was the first Human to return to Earth and give details of the Covenant Civil War.
Battle of OnyxEdit
Lash was quickly ordered to take the Dusk to Onyx to provide the UNSC Stalingrad and its battle group with tactical data as well as observe the battlefield. Against Lash's better judgment, the Stalingrad's battle group charged into Onyx and was crushed by superior Covenant forces, forcing the Dusk to float adrift in space until they could escape. This opportunity came when Onyx exploded into a Shield World. Lash was able to escape the Battle of Onyx and keep his crew alive.
- Lash owns an ancient spring-and-gear wristwatch, which he received from his father upon his graduation from OCS. He always keeps it wound tight for luck, as his father had advised.
