'''Cleyell''' was a [[Human colonies|colony]] planet of the [[Unified Earth Government]] located among the [[Outer Colonies]].<ref name="HE17">'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 17|Issue #17]]''</ref>

{{Quote|This one, Cleyell, was recent. They hit the only city left on the planet. Those folks made it all the way through the war… for this.|An Orbital Drop Shock Trooper<ref name="HE17"/>}}

During the [[Human-Covenant War]], Cleyell was attacked and partially [[Glassing|glassed]] by the [[Covenant]]. However, the [[United Nations Space Command]] was evidently able to repel the Covenant forces, though only a single city on the planet survived the Covenant's assault. Cleyell remained untouched for the remainder of the Covenant War and the colony's remaining population continued to live on the planet.<ref name="HE17"/>

Following the Covenant War, although the Covenant had been dissolved, Cleyell was attacked in [[2556]] by a [[Covenant remnants|remnant]] of the former alien empire who subsequently glassed the remaining city on the planet. With hostile [[Kig-Yar]] raiders scavenging Cleyell's surface, the survivors contacted the [[Unified Earth Government]] for assistance.<ref name="HE17"/> In response, the UNSC launched [[Mission to Cleyell|a massive rescue operation]] to Cleyell<ref name="tanaka">[https://www.halowaypoint.com/en-us/universe/characters/holly-tanaka '''Halo Waypoint''': ''Holly Tanaka'']</ref> that included [[UNSC Marine Corps]]' [[Orbital Drop Shock Troopers]] and elements of the [[UNSC Army]]'s [[412th Engineer Command]] aboard {{UNSCShip|Cascadia}}. After arriving at Cleyell, upon the suggestion of [[Sergeant]] [[Holly Tanaka]], a [[lieutenant commander]] aboard ''Cascadia'' deployed Army and Marine search-and-rescue teams to rescue the stranded colonists on the surface,<ref name="HE17"/> rescuing dozens of colonists from death or [[Slavery|enslavement]] at the hands of the Kig-Yar.<ref name="tanaka"/><ref name="HE18">'''Halo: Escalation''', ''[[Halo: Escalation Issue 18|Issue #18]]''</ref>
