Insurgency on Elysia

The Insurgency on Elysia was a major series of engagements on the Outer Colonies planet of Elysia during the waning years of the Insurrection. Since the Insurrection was mainly fought away from urban centers, civilian casualties were minimal. To prevent Elysia from losing it's reputation as a peaceful, paradise planet, ONI and the UNSC would completely classify the Insurrection.

Background
Prior to the beginning of hostilities, Elysia had enjoyed relative peace during the Human-Covenant war. Being a planet in the Outer Colonies, the population lived under constant fear of invasion, and had limited contact with the Inner Colonies to prevent Elysia from being discovered.

Due to this disconnect, rural societies on Elysia would take up arms as they believed the UNSC was ill-equipped and ill-prepared to defend the planet from a potential Covenant threat. Upon the UNSC demanding their disarmament, hostilities would begin.

The Insurrection
Insurrectionist activities began on the 7th of September, 2536. Lead by Michael Christiansson, Kayode Adetola and Carlos Smith, all three being prominent secessionists on Elysia or Society, they secured significant victories in the opening month of the Insurrection as the UNSC Garrison on the planet did not expect such a seemingly stable planet to descend into war. The Insurrection would have captured significant areas in the rural regions of the planet, and were posing a direct threat to the capital city of Carpentaria by the 3rd of November.

The UNSC had organised both a significant military and militia force by the 3rd of November, and lead by Devin Weeks, were able to successfully hold off a series of attempts by the Insurrection to attack Carpentaria. The offensive would drain Insurrectionist resources and lead to them taking significant casualties, with their military presence on the planet being significantly weakened. Exploiting their loss of momentum, the UNSC launched a counterattack which would last until the 20th of January, 2537, by which the UNSC would have successfully captured or destroyed all major Insurrectionist bases on Elysia and caused the ringleaders to retreat off-world. Major military operations ended on the 22nd of January, when organised groups collapsed without leadership.

Aftermath
Following the 20th of January, minor insurgencies continued on Elysia until the First Battle of Elysia, in which the very few remaining Insurrectionists would join the UNSC and assist in their defense of the planet. Following the UNSC victory on Elysia, all remaining Insurrectionist factions on the planet entered into a peace agreement with the UNSC.
