Planetary HistoryEdit

Reunification WarEdit

Nexus Ri was a world on the border between the Outworlds Alliance and the Draconis Combine when Operation UNION HOLD began in 2581. With the intention for forcibly incorporating the Outworlds Alliance into the Star League following the mass rejection of the Pollux Proclamation in 2575 by the major Periphery states, the invasion of the Outworlds Alliance saw two corps of Star League Defense Force troops and a mixed brigade of DCMS forces begin systematically occupying Alliance worlds. Nexus Ri escaped the attentions of the Outworlds Alliance Task Force until September 2582.[5]

Outraged by the manner in which the Federated Suns managed to annex a number of Outworlds Alliance worlds in defiance of the plans of General Amos Forlough, commanding officer of the Outworlds Alliance Task Force, Coordinator Hehiro Kurita responded to what he perceived as an affront to his honour by recalling the various regiments of the Galedon Regulars due to act in support of Forlough's planned strike on Ki Zoban and instead instructed Sho-sho Masao Igushi to target worlds along the Combine/Alliance border. The Coordinator also removed all of the materiel the Combine had supplied to the task force equipment caches to support the Galedon regiments, disrupting or preventing months of planned SLDF combat operations. While Forlough raged over Kurita's actions, Sho-sho Igushi deployed three regiments of Galedon Regulars against the worlds of Kazanka, Nexus Ri and Zlatousi.[5]

When the 4th Galedon Regulars faced the Alliance forces on Nexus Ri, they found that the Alliance defences were stronger and deeper than originally anticipated. The 4th had the support of paired regiments of armor and infantry, and all of the 'Mechs on Nexus Ri belonged to the 4th, with the exception of a handful of old, light Alliance 'Mechs. The mass executions on Medron, Valentina and other occupied worlds by both Combine and Star League forces had increased militia recruitment tenfold; while the Alliance 2nd Armored Division was already in place on Nexus Ri, it was backed up by a local militia which provided both armor and heavy infantry support. While the militia units lacked experience, they had been trained well by advisors from the AFFS provided by the Federated Suns under the Tancredi Accord, and had superior numbers on their side.[5]

Rather than a swift rout of light militia forces as had happened on worlds like Schirmeck, the battle for Nexus Ri rapidly became a conventional war; the Mechs of the Galedon Regulars made swift gains initially, but were facing twice their number of tanks and infantry and the Alliance forces consistently surrounded the Combine 'Mechs, preventing them from breaking out to attack the civilian population. The Combine forces still made daily gains, and were supported by weekly supply shipments, but the Alliance forces resisted for the remainder of 2582; by the time the 2nd Armored Division had been reduced to a ghost of it's former self and forced to retreat off-world on the 12th of January 2583, the resistance offered by the Alliance forces on Kazanka, Nexus Ri and Zlatousi had forced the Combine forces to burn through a supply reserve meant to support the entire campaign against the Alliance for a year in just three short months.[5]

Nexus Ri was lost to the Outworlds Alliance, and would remain an occupied world under the 4th Galedon Regulars until the 1st of August 2585 when it and 13 other worlds were formally ceded to the Draconis Combine as a part of the terms laid out within the Treaty of Cerberus. Despite being a loss for the Alliance, the battle for Nexus Ri helped buy time for the Alliance to build up it's forces and further fortify inner worlds for the battles that would come in later years of the invasion.[6]
