May
The allied 1st Ceti Hussars uncover a cabal loyalist officers sabotaging their military readiness
Lucy convinces Katherine to fund Achernar Battlemechs and Corean Enterprises to start building battlemech production lines on loyalist worlds in Nunivak and Point Barrow Combat Regions to reward them - suggesting a carrot-and-stick method to keep the regions (both of which are fairly close to New Avalon) loyal to Katherine and also give her back up supply lines.
July
Corean Enterprises start building a small factory on Chirikof to manufacture the VLK-QD, using tooling being replaced as they gear up to build newer designs on New Avalon.
August
Achernar Battlemechs start building a small factory on Defiance to manufacture the DV-7D Dervish, using tooling being replaced as they gear up to build newer designs on New Avalon.

General Gray takes over control of the Broken Wheel Combat Region and seperates it into two PDZ.

November
Further reinforcements from the 1st Crucis Lancers arrive on Woodbine, rapidly swinging the tide in the Allies favour. The Third Regulars surrender by the end of the month. Elements from Kilbourne take over responsibility for their remaining equipment.

Having infiltrated elite infantry into loyalist positions, the 1st Ceti Hussars quckly demolish the Bryceland DMM. Elements from Woodbine and Kilbourne move in to rebuild the DMM while the Ceti Hussars head back to Kesai IV in light of the clashes between forces loyal to House Sandoval and the DCMS
August
Remainder of 1st Crucis Lancers arrive on Tsamma to reinforce Tancred Sandoval
Hansen's Roughriders and elements of the Warren CMM assault Panpour but are surprised by the Islamabad CMM, which rather than supporting them assault their flank.

April
Assembling members of the High Council of the Federated Suns, from worlds in the Chirikof, Minette and Woodbine Operational Areas on Minette, Lucy Davion persuades them to form a provisional government for what is dubbed the 'Outback March' and to remain neutral in the Civil War. At a stroke, Loyalist and Allied forces are denied more than a third of the territory of the Federated Suns. Katherine is furious, but having sent her last major reserve to New Syrtis, can't spare major forces to bring the region back in line although MIIO is turned loose. The Allies, on the other hand, are satisfied that the region is denied to Katherine.
July
1st Royal Cavaliers mistakenly employ chemical weapons against the Crucis Lancers on Tsamma, breaking the allied momentum and seriously harming Tancred Sandoval.
DCMS reinforcements reach Kesai IV pushing the Ceti Hussars further onto the defensive

Presenting the image of formed units, they demand the departure of the Royal Cavaliers and the Crucis Lancers from Tsamma. Badly battered, allied and loyalist alike comply. The demand is made in the name of Lucy Davion and Derrick Gray acting as Minister and Marshal, respectively, of the Outback March

3067
April
Formal surrender of Katherine Steiner-Davion ends the Civil War.
May
Yvonne Steiner-Davion grudgingly accepts actions of the 'Outback March' and its leaders. Albion Hussars are integrated into the AFFS and for the most part redeployed to cover the border regions of the Capellan and Draconis Marches, both of which need reinforcement badly. Surviving elements of the Royal Cavaliers (savaged on New Avalon) are redesignated 8th Albion Hussars. Derrick Gray is formally named commander of the Albion Hussar corps while Lucy Davion resigns her commission and is appointed to a committee considering the possibility of forming an Outback March.
