In June of 2494, traitorous members of the Colonial Military Administration armed insurrectionists on Eridanus II under the leadership of UNSC Marine-turncoat Colonel Robert Watts. The insurgents executed a campaign of bombings, kidnappings, and assassinations of politicians which negatively impacted Eridanus II's shipping industries. Additionally, the insurgents garnered a fleet of ships supplied by the CMA and begun preying on shipping vessels.
In December of 2494, the Eridanus Government officially requested aid from the UEG's United Nations Space Command. The UNSC finally responded in January of 2496 by launching Operation: CHARLEMAGNE. During the following engagements, the UNSC defeated the rebel forces and the Eridanus Government regained control of Eridanus II. However, in 2513, Watts had formed the United Rebel Front and his forces had regained enough strength to attempt to overthrow the Eridanus Government again, hoping to use Eridanus II as a base of operations and drag the CMA into a costly guerilla war. The UNSC anticipated the URF's intents and launched Operation: TREBUCHET. The UNSC was eventually able to decimate most of the URF forces on Eridanus II before they could establish a stronghold on the planet, though many of Watts' rebels managed to flee to the Eridanus system's asteroid field.
