Planetary History[edit]

Early History[edit]

Having become independent as a result of the Demarcation Declaration, Pollux was subsequently added to the resurgent Terran Hegemony; whilst some worlds joined the Hegemony during its early years as a result of diplomatic and trade incentives, many more were conquered in "campaigns of persuasion" launched by Director-General James McKenna, the first of which began in 2316 and ended with the capture of Towne in 2317. Pollux was one of the worlds added to the Hegemony during or around the time of this first military campaign.[29][1][30] By the end of the Reunification War Pollux was a member of the Tyrfing Province of the Terran Hegemony.[5]

Fourth Succession War[edit]

Following the sudden invasions of several League worlds by the Tikonov Free Republic and a daringly successful invasion of Callison by mercenaries employed by the Lyran Commonwealth in mid-3029, Captain-General Janos Marik found himself in the midst of an unanticipated crisis. In addition to the conquest of Callison, LCAF communications traffic and movements had spiked sharply, creating the impression of an impending offensive against the League. Faced with what he believed to be the plausible threat of a large-scale attack aimed at the region of the League near Terra, Janos was more concerned with saving the six or seven assorted BattleMech regiments present within the region than he was with retaining the worlds, as he believed that the offensive would most likely be aimed at snipping off the corner of the League closest to Terra - and to both the Federated Suns and the Tikonov Free Republic. Pollux was one of the systems abandoned by Janos, who would learn later that he had been deceived by an effective campaign of smoke and mirrors arranged by the Commonwealth General of the Armies, Edward Regis, to deter the League from launching an invasion of the Commonwealth while the LCAF was heavily committed to its invasion of the Draconis Combine.[31][32][33]

Operation Guerrero[edit]

Pollux was invaded in the second wave of Operation Guerrero by the Thirty-fourth Marik Militia. The defending militia was limited to one regiment of armor and one of infantry. The other five regiments that were on the planet either withdrew to the Lyran Alliance or joined the Free Worlds League. Free Worlds League troops took over within a week.[34]


On 14 September 3071, the pro-Blakist garrison on Pollux was raided by forces from the Free Worlds Resistance, the organization headed up by Alys Rousset-Marik and which was also responsible for raiding another Blakist garrison on Hamilton.[35][36] Pollux was raided again on the 23rd of September 3075, one of three worlds in the Protectorate to be raided simultaneously by unidentified forces. The raiders damaged the defending Protectorate and Militia forces, and were rumored to actually be drawn from the Word of Blake's own Shadow Divisions.[37][38]

Forces from the Free Worlds League front of Operation SCOUR liberated the nearby world of Graham IV in March 3078, and as they moved to liberate Pollux later in the month they received unexpected assistance and aid from an uprising that resulted in a popular revolt.[22] By June 3078 all of the Free Worlds League task force had gathered on Pollux to rest and refit prior to the coalition assault on Terra, with the exception of Group II, who were still bogged down in the conflict on Liberty.[39]
