Shoreditch Incident

The Shoreditch Incident was an event in which Imperial and Renegade Dalek factions battled in the eponymous area of London in November 1963. The area was evacuated to prevent civilian casualties. At that time, the Daleks were engaged in the Imperial-Renegade Dalek Civil War. Each side tried to procure the Hand of Omega.

Preparations by both sides
A Renegade Dalek faction (from approximately the 30th century, according to the Seventh Doctor) and an Imperial Dalek faction arrived in Shoreditch in 1963. (TV: Remembrance of the Daleks) At least one Renegade Dalek had come to London to seek the Hand of Omega, which the First Doctor had concealed in a coffin and consigned to an undertaker in or shortly before November 1963. (COMIC: Time & Time Again; TV: Remembrance of the Daleks)

The Imperials set up a concealed transmat in the basement of Coal Hill School to transport themselves there. They enslaved the headmaster, H. Parson. The Renegade Daleks employed George Ratcliffe and linked Judith Winters, a schoolgirl, to their Battle Computer so her young imagination could generate ingenious stratagems to defeat the Imperial Daleks. (TV: Remembrance of the Daleks)

On 22 November 1963, the Doctor returned in his seventh incarnation with Ace McShane in tow. From his perspective, several hundred years had passed since his departure, although he had visited the village's 1985 future in the interim. (TV: Remembrance of the Daleks, Attack of the Cybermen)

The course of the conflict
A human military force, the Intrusion Countermeasures Group, was led by Group Captain Ian Gilmore. Dr Rachel Jensen and her assistant Allison Williams were their scientific advisors. The troops had a brief battle with a Renegade Dalek at Foreman's Yard. For the most part, however, the group ensured the evacuation of the area to minimise human casualties and allow the Doctor to put his plans into motion. (TV: Remembrance of the Daleks)

An Imperial shuttlecraft landed in the yard of Coal Hill School. Aided by the Special Weapons Dalek, the Imperial Daleks won their battle on the streets of Shoreditch. The Imperial Daleks took the Hand of Omega, as the Doctor had planned all along. Davros (as "Emperor" of the Imperials) (TV: Remembrance of the Daleks) plotted to detonate the second sun of the Daleks' homeworld Skaro, (PROSE: The Stranger) making it go supernova, and giving the Daleks the power of unlimited time travel. In the Imperial Daleks' time zone, he did so. This action, however, destroyed the planet and the Imperial fleet. (TV: Remembrance of the Daleks)

The Dalek Prime later claimed that it was not Skaro, but another planet, Antalin, that was actually destroyed. (PROSE: War of the Daleks)

On Earth, the Doctor talked the last Renegade Dalek, the black Supreme Dalek, into self-destructing. (TV: Remembrance of the Daleks) However, Judith Winters, the young girl linked to his mind, was broken mentally for the rest of her life. (PROSE: In the Community)

Human reaction
From the viewpoint of many key scientific and military authorities in Great Britain, the conflict constituted undeniable evidence that aliens existed. The conflict was later named "the Shoreditch Incident" by these authorities. (PROSE: Who Killed Kennedy)

The Shoreditch Incident was also the title of a book on the incident written by ex-UNIT officer Hamlet Macbeth. (PROSE: The Left-Handed Hummingbird, Return of the Living Dad)

Alternate timeline
In an alternate timeline where WOTAN succeeded in taking over the minds of large portions of the population, Dalek artefacts from the Shoreditch Incident were recovered by the British, who began to make slight advances in time travel studies and, by 2006, hoped to use it to win World War III, which began as a result of the broken world left behind in WOTAN's wake. Because WOTAN had destroyed many great minds, the only people left to carry out any experiments were, as the First Doctor opined, "idiot[s]."

The First Doctor prevented these studies from taking place in October 1972 of this timeline by transporting the artefacts into the Sun. Nevertheless, the appearance of a Dalek manipulator arm caused alarm for both the Doctor and Susan, who, by this point in their personal timelines, had only encountered the Daleks once before. The Doctor concluded that the Daleks must have visited Earth at some point. (PROSE: The Time Travellers)

This timeline was ultimately totally averted when the First Doctor, later in his personal timeline, changed history by defeating WOTAN in 1966. (TV: The War Machines)
