Lagash

Lagash was an Outer Colony located on the towards the very edge of Human space. Though a lush and habitable world, Lagash was rife with poverty which led to it becoming a hotbed of insurrectionist activity. It was the site of several protracted campaigns against local insurgents by the UNSC, especially during Operation: TREBUCHET, where it saw vicious urban combat as UNSC Army Troopers and Marines fought street to street with local rebel forces, a bloody melee that led to several high profile massacres committed by both sides. UNSC operations on the planet and the naval blockade in orbit only worsened matters as poverty increased and more people joined the insurgents.

In early 2526, Lagash and the other worlds in the Vevina sector fell under attack by the alien hegemony known as the Covenant. While harsh fighting was occurring on Harvest and several neighboring worlds, a minor Covenant fleet entered the system and laid siege to the planet. The only thing that prevented the immediate destruction of the world was, ironically, the heavy presence of UNSC forces in the system to combat the rebels. After managing to fight back against the initial wave, Covenant reinforcements only several weeks later resulted in the almost complete destruction of the UNSC forces present and the glassing of the world's population centers.

Following the war's end in March, 2553, Lagash was selected as one of dozens of worlds suitable for potential recolonization. A terraforming force was dispatched, and by late 2556, refugees began returning to the world.
