Exxilon Gambit

The Exxilon Gambit, known to the Time Lords as the Exxilon Incident, (PROSE: Dalek Combat Training Manual) was the final action of the Third Dalek War, (PROSE: The Secret Lives of Monsters) identified by the Time Lords as taking place in the late 27th century. (PROSE: Dalek Combat Training Manual) It took the form of numerous expeditions by opposing parties to the planet Exxilon to acquire the rare mineral of parrinium. (TV: Death to the Daleks)
Human historians postdating the Last Great Time War indicated that the Daleks' germ warfare campaign which culminated with the Exxilon Gambit came multiple centuries following the 26th century Dalek War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
== History ==
=== Origin ===
During the Third Dalek War, (PROSE: The Secret Lives of Monsters) the Daleks launched a form of germ warfare, infecting the Outer Worlds of the Earth Empire with space plague. The colonists living on the Outer Worlds discovered that the plague could be cured by parrinium. Though extremely rare on Earth, it existed in abundance on Exxilon. The Marine Space Corps dispatched a small team on an expedition to Exxilon to acquire the parrinium and save millions of lives.
Though the Earth Empire was at war with the Daleks, they did not seem aware that the Daleks themselves were the instigators of the plague. The Daleks, knowing of the expedition to Exxilon, sent their own squad to the planet, tasked with acquiring the parrinium before the humans did (TV: Death to the Daleks) in an attempt to turn the tide of the war. (PROSE: The Secret Lives of Monsters) Whilst another account noted that it was possible that Dalek-controlled worlds had also become infected with the plague, (PROSE: The Whoniverse) a group of Dalek-focused historians came to write that the worlds in Dalek territory were completely unaffected by the plague they had developed. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
A dissenting account claimed that the plague was merely an opportunity that the Daleks had exploited, and that they were immune to it as a result of their work in curing the Movellan virus which had earlier afflicted them. (PROSE: The History of the Daleks)
The Dalek expedition came in a small saucer and used modified silver Dalek drone casings with "multiphase" black sensor globes like the grey Daleks, designated by the Time Lords as the Type V Dalek. Their leader was distinguished by its amber luminosity dischargers. (TV: Death to the Daleks, PROSE: Dalek Combat Training Manual)
=== Alliances of convenience ===
Upon arriving on Exxilon, the Earth expedition became stranded as a result of the Great City of the Exxilons drawing away power from their ship. The crew was attacked by the native Exxilons. Some of their number were killed and Commander Stewart was badly injured. His second-in-command, Captain Richard Railton, took over as leader while waiting for a relief ship. When the Daleks arrived, their saucer also fell victim to the power failure. With neither side possessing advanced weaponry (even the Daleks' gunsticks no longer worked), the Daleks and the humans, at the insistence of the Third Doctor, who was also stranded, were convinced to work together for the duration of the power failure. The Daleks kept their true intentions a secret and claimed they were also victims of the plague.
Railton was killed by the Exxilons and the combined expedition surrendered to Exxilon captivity. Though Stewart wanted Lieutenant Peter Hamilton to take command, the Commander died before he could enforce it and Lieutenant Dan Galloway took charge instead. Dalek reinforcements arrived with functioning projectile weaponry and blackmailed the Exxilons into providing slaves for a parrinium mining operation, to be overseen by Galloway. In return, the Exxilon High Priest asked only that the Daleks and Marines help them eliminate the splinter group of Subterranean Exxilons. The Doctor was distanced from the standing alliance after attacking the High Priest to save Sarah Jane Smith. The two made contact with the Subterraneans.
=== Attack on the Great City ===
The Doctor agreed to help the Subterraneans free the Exxilons from the influence of the Great City, which was blamed for the fall of the advanced Exxilon civilisation. The Daleks also began planning to assault the city once it was identified as the source of the power failure and after its defences attacked Daleks and Exxilons at the dig site. The Doctor and Bellal ventured into the City, as did two Daleks on a separate mission, to interfere with its functions from within. Meanwhile, the Dalek leader recruited Galloway and Hamilton to attach explosive charges to the City's beacon from the outside. The twin actions led to the destruction of the City, and restored power to the expeditionary vessels. This also meant the end of the truce.
=== Recovery of the parrinium ===
While most of the attention was focused on the City, Sarah Jane Smith and civilian scientist and geologist Jill Tarrant were able to store the mined parrinium aboard the Earth ship while replacing the Daleks' supplies with bags of sand. When the Daleks took off, they prepared to bombard Exxilon with plague missiles. However, Galloway took off with them as a stowaway and detonated a remaining explosive charge, obliterating the Dalek saucer. With the parrinium secure, Hamilton and Tarrant took it back to the Outer Worlds. (TV: Death to the Daleks)
=== Aftermath ===
The expedition constituted the last acts of the Third Dalek War. (PROSE: The Secret Lives of Monsters) Although the Daleks were defeated, the cost for Earth had been high, especially when combined with that of the Human-Draconian War and the Second Dalek War before it. The Earth Empire's vast population growth was brought to and end and with it, so was its expansionist phase. (PROSE: The Chase)
On the destruction of the Exxilon City, the Doctor considered it "rather a pity, in a way," as it meant the loss of one of the 700 Wonders of the Universe. (TV: Death to the Daleks) Following the Cyber Wars of the 250th Millennium, Webley would identify the Chess-playing Cyberman as the 699th Wonder of the Universe. (TV: Nightmare in Silver)
The success of the Marine's expedition led to the development of a diplomatic relationship between Earth and Exxilon. In exchange for further supplies of parrinium, Earth helped restructure Exxilon society into a democracy, with Bellal being elected leader and working to reunite the two factions of his people. Earth also supplied the Exxilons with technology, education and means of farming and fertilising the soil. Some of the Exxilons struggled to accept this new way of life, still feeling as if their loyalty belonged to the dead City, and remaining aggressive and suspicious. They claimed Earth had not helped Exxilon develop out of a benevolent desire but rather to secure the parrinium for themselves. Bellal did not object to this, but nevertheless acknowledged that the arrangement had led to mutual benefits. As they developed, Bellal was still able to maintain balance among his people while the Marine Space Corps continued mining parrimium. (AUDIO: The Dalek Protocol)
According to human historians postdating the Last Great Time War, the failure of the Exxilon initiative led the Dalek Supreme Council to launch a full-scale invasion of Mutter's Spiral before its civilizations could sufficiently recover from the plague. Having overran the Draconian Empire in their onslaught, the Daleks faced the human-led Combined Galactic Resistance in a conflict which was halted by the Good Dalek Incident, after which the Daleks turned their attention to time travel and the Outer Galaxies, where they fought another war. They eventually attempted a new invasion of the galaxy in the year 4000. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
While it remained unclear to historians whether the Daleks themselves also fell victim to the plague, (PROSE: The Whoniverse) a mutation of the space plague soon spread after it evolved and once again threatened the Outer Worlds. The Dalek Supreme admitted to the Fourth Doctor that this second wave was capable of penetrating Dalek force fields and infecting them as well. They contacted the Exxilon Gislen, an opponent of Bellal, and manipulated him into constructing another beacon on the City's ruins. The renewed power drainage disrupted the Marine Space Corps' mining operations before the Marines destroyed it, but the delay allowed the Daleks to catch up with the Earth fleet in a bid to capture the parrinium for themselves. When their sleeper agent, Mark Seven, resisted their control and threatened to destroy both fleets, the Daleks ultimately retreated. (AUDIO: The Dalek Protocol)
The events on Exxilon were recorded in a book by Hagan Garsonmous entitled A History of the Dalek Wars. (PROSE: The Secret Lives of Monsters) Another book about universal history seemed to attribute the plague and the Exxilon expedition as stemming from to the Dalek conflict that was sparked in the year 4000 by the attempt to develop the Time Destructor. However, its wider account seemed to offer a more general and not-necessarily linear account of the Dalek Wars as a whole. (PROSE: The Whoniverse) Nevertheless, by another account, Bellal was still leader of the Exxilons during the period the Space Security Service was active against the Daleks. (AUDIO: The Dalek Protocol)
A dissenting account claimed that the Exxilon Gambit fell within the Daleks' civil conflict against Davros, following his apparent death in the Duplicate Incident and before the Daleks discovered Davros on Necros. (PROSE: The History of the Daleks)
From the Doctor's perspective, the Exxilon Gambit was among his last encounters with the Daleks before the Time Lords sent his fourth incarnation to Skaro to interfere with their creation, after it was foreseen that there would come "a time when they will have destroyed all other lifeforms and become the dominant creature in the universe."
For the Doctor's companion, Sarah Jane Smith, Exxilon marked her first encounter with the Daleks, who were introduced to her by the Doctor as "living, bubbling lump[s] of hate." She was still in the Doctor's company at the time of his mission to Skaro. By that point, her experience with the Daleks, who she would describe as "the most evil creatures ever invented", left her with enough of an impression that she urged him to destroy them at their beginning. (TV: Genesis of the Daleks) Decades later, when faced with a full-scale Dalek invasion of Earth, she broke down in tears out of fear for the life of her son, Luke Smith. (TV: The Stolen Earth) Nevertheless, she would join with the Tenth Doctor and the Children of Time to defeat the Daleks once more. (TV: Journey's End)
Some of the Daleks survived, but were classified as insane and taken to the Dalek Asylum where they were stored in intensive care. The Eleventh Doctor encountered these Daleks when he was sent to the planet by the Parliament of the Daleks to help destroy it before the prisoners could escape. (TV: Asylum of the Daleks)
In the post-Time War universe, this incident was covered as a part of known Dalek history in The Dalek Conquests, a documentary which was itself produced following the Van Statten Incident on Earth in 2012. (AUDIO: The Dalek Conquests)
== Behind the scenes ==
* DWM 77's History of the Daleks dates the Dalek time travellers to c. 3767.
* The Discontinuity Guide claimed that the Daleks' Exxilon Gambit followed their unrecorded first encounter with the Third Doctor, which occurred somewhere between the 23rd and 25th centuries, but preceded the Draconian Gambit.BBC.co.uk 'Discontinuity Guide' article on Dalek History: Part One in the original series of Doctor Who It is further noted that, since the Fourth Doctor inadvertently changed Dalek history so that Davros survived, this event would have occurred vastly differently if it happened at all in the new timeline.BBC.co.uk 'Discontinuity Guide' article on Dalek History: Part Two in the original series of Doctor Who
* A History of the Universe and aHistory arbitrarily date the events of Death to the Daleks to 2600 as it takes place after (or at the end of) the Dalek Wars. Likewise, The Dalek Handbook dates these events as taking place during the 27th century. Given that the Second Dalek War of the 26th century began circa 2540, (TV: Frontier in Space) lasted around 40 years (PROSE: Prisoner of the Daleks) and took place in the same period as the Third, (PROSE: The Chase) this dating seems reasonably accurate.
** This dating was later muddied, however, by The Dalek Protocol, which returns to Exxilon "many years" after Death to the Daleks. While the story does not give its setting, it involves the SSS who were active in the 41st century. Bellal's presence in the story makes it unlikely that over a millennia has passed since the Exxilon Gambit.
* The Dalek Handbook takes the appearance of the Daleks in the Exxilon Gambit as evidence that the taskforce were Daleks native to the 27th century time period whom had been subsumed into time travelling grey Dalek forces from the future, beyond the year 4000.
