With a large uprising in the Eridanus system, The United Earth Government began its assault in 2513 and ended combat operations sometime in 2526, being the largest Conflict in nearly four hundred years.
Citizens largely perceived this battle as positive, that and widespread support lasted for Atleast three years, until 2516, when the UNSC lost large amounts of grounds to Insurrectionist armies. The UNSC's response was to send more troops to the planet, instead of negotiating like many politicians on Earth called for.
