Shoreditch Incident

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

A Human military force, the Intrusion Countermeasures Group led by Group Captain Gilmore, and the the Doctor also intervened at this time. (DW: Remembrance of the Daleks)

The conflict was later naamed "the Shoreditch Incident" by Human authorities aware of alien intervention in Earth affairs, such as UNIT. (MA: Who Killed Kennedy) The Shoreditch Incident was also the title of a book on the incident written by ex-UNIT officer Hamlet Macbeth. (source?)
