Aaron DeChavilier (13 October 2714 - 15 May 2801) was the Deputy Commanding General of the Star League Defense Force (SLDF) and the best friend of SLDF Commanding General Aleksandr Kerensky. DeChavilier is remembered in history not for his accomplishments in life, but for his death, that resulted in the infamous DeChavilier Massacre.[1]

Early Life and Military Service[edit]

Born on the Federated Suns world of Kestrel, Aaron DeChavilier's formative years and future path were shaped by the War of Davion Succession, the young boy closely following the course of the conflict and deciding to join the SLDF after watching them crush the invading Draconis Combine forces. DeChavilier was initially unable to gain admittance to the Star League military academies he had set his sights on, instead entering the Suns' Sakhara Academy for his first year with his impressive grades, especially with regards military studies, earning him a place in the Star League run Albion Military Academy's corps of cadets. Though having to repeat his first year because of his entry into a new academy, DeChavilier excelled, easily qualifying as a MechWarrior.[1]

Assigned to the 320th Dragoon Regiment upon graduation, by the end of his first year of active service the 320th had earned top honors in the 2736 Martial Olympiad with DeChavilier himself having the second-highest individual score, earning him a promotion to Lieutenant and position within the next class of the Gunslinger Program. He would also briefly meet his future friend Aleksandr Kerensky at the 2736 Olympiad. Over the next ten years DeChavilier quickly rose to first company and battalion command within the 320th Dragoon Regiment before receiving overall command of the 3843rd Battle Regiment. Facing some of the heaviest fighting against "bandit" forces during the Third Hidden War, his unit's fantastic performance and high level of morale even in the face of difficult and stressful pirate-hunting duties earned DeChavilier promotion to Lieutenant General and transfer to the SLDF's Citadel on Terra. Again encountering Kerensky during this period, DeChavilier was deeply unhappy at such a staff assignment and after a year was able to manage a transfer to the 149th BattleMech Division as assistant division commander, rising to command of the entire division itself in just a year's time.[1]

DeChavilier would serve in this position for four years, guiding the 149th through the turmoil and confusion following the death of First Lord Simon Cameron, before he was offered command of the XXI Corps, one of the three SLDF corps responsible for the defense of the Terran Hegemony. It was during his time with XXI Corps that now SLDF Commanding General Kerensky truly took note of DeChavilier, seeing in him a good tactician but more importantly a ceaseless motivator and peerless organizer, someone who was also intensely loyal, dedicated and unimpeachable. From that point on, the careers of both men became linked, ultimately becoming a deep friendship after Kerensky promoted DeChavilier to General and command of the First Army in 2758. In 2760 Kerensky advanced DeChavilier to the position of Director of the Regular Army, making him responsible for the training and motivation of the SLDF's millions of soldiers, pilots and MechWarriors.[1]

Star League Civil War[edit]

After the outbreak of the Periphery Uprising, DeChavilier would receive his final promotion, becoming Deputy Commanding General of the Star League Defense Forces. Charged with preparing the entire SLDF for war, DeChavilier followed Kerensky into the field, inspiring and leading his armies as they went to war against the rebellious Territorial States.[1]

In 2771, DeChavilier planned and organized Operation INTRUDER as part of the Hegemony Campaign. This plan called for all the surviving Regimental Combat Teams to start reconnaissance probes and raids into Amaris held worlds in a effort to gain intelligence and contact resistance groups; paving the way for Operation CHIEFTAIN the main assault.[2]

DeChavilier was placed in charge of Task Force Sun during Operation CHIEFTAIN in 2772, this gave him overall command of three Army Groups; the Fourth, the Nineteenth and the Twenty-first.[3]

Marriage and Children[edit]

Aaron DeChavilier married and had five children. Like General Kerensky, DeChavilier had left his family behind in their Unity City home on Terra after deploying into the Periphery, with his wife Cynthia and his three youngest children - Julia (born 2749), Benjamin (born 2750) and Kristina (born 2760) - killed by agents of Stefan Amaris searching for members of House Cameron in the wake of the Amaris Coup. His two eldest children, Major Roger DeChavilier (born 2739) and Colonel Angela DeChavilier-Banacek (born 2738) would both ultimately die during Operation CHIEFTAIN.[1]


By the time we got to them… These weren't human. They couldn't talk. They just lashed out at us… The doctors are already saying they will never again live aboveground in society. It would be better to put them down now. More humane than letting them live another minute. How the hell?
